Successful Running? State of Mind, or State of Emotion?

What happens to your brain during runners high?
In the previous post I explained how research had demonstrated an endorphin driven runners high. Endorphins are the molecules produced in the pituitary gland and the hypothalamus that act as the bodies 'homemade' opiates. These act to relieve pain and produce a feeling of calm and well being. Endorphins are also produced and provide the feelings experienced when we eat spicy food, fall in love or have an orgasm.
The endorphin hypothesis for runners high holds that when strenuous exercise takes a person over a physical threshold, endorphin production is activated. Endorphins are released during long, continuous workouts, when the level of intensity is between moderate and high, and breathing is difficult. During a release of endorphins the person may be exposed to bodily harm from strenuous exercise after going past their body's physical limit. With runners this means that they can keep running despite pain, surpassing what they once considered to be their limit, in turn experiencing the phenomenon as pleasurable. It also goes someway to accounting for the crazy look in the eyes of runners and their behaviour after a heavy workout!
Boecker's research in 2008 showed for the first time that an increase in the release of endorphins occurred in certain parts of the athletes' brains after conducting scans of runners 2 hours after exercise (compared to their resting state beforehand). Thus more of the bodies own opiods were released in runners in the study, who also reported a significant increase in euphoria and happiness ratings compared to their resting state.
However, it is also suggested by researchers that endorphins are just some of the many chemicals that contribute to runner's high. Other candidates include epinephrine, serotonin, and dopamine. Yesterday, whilst researching this subject I found evidence in the New York Times proposing that the endocannabinoid system may be more responsible for runners high than endorphins.
The main thrust of this argument is that endorphins, are composed of relatively large molecules, “which are unable to pass the blood-brain barrier,” (Hill, 2011 in the article here). This contradicts Boecker's findings, and according to Dietrich and McDaniel (2004) “several prominent endorphin researchers have criticised the endorphin hypothesis for being “overly simplistic” and “poorly supported,” though it should be noted these views were made before Boecker's study. Instead, the endocannabinoid system, is proposed by researchers such as Hill as being more responsible for runners high as these molecules produced naturally by the body are small enough to be able to cross the brain blood barrier and thus account for the “unexpected psychological changes, such as euphoric sensation, a heightened sense of well being and a transcendence of space and time.” These are the same sensations experienced in the brain when people take marijuana, as the drugs active ingredient also binds to the same receptors.
Authors behind the endocannibinoid hypothesis for runners high (such as Dietrich and McDaniel) don't claim that their theory is 100% sound, and want researchers from a variety of backgrounds to investigate further. One criticism that can be levelled at a lot of the research is that it relies on findings from research on rats, and we cannot directly take results from such studies and apply them to humans. However, Dietrich and McDaniel, and another study by Dietrich in 2003 was researched on humans to go some way to prove the cannibinoid hypothesis.
I've emailed Dr Boecker to try and see if he is able to respond to the evidence presented by the New York times article and studies proposing the cannibinoid hypothesis. If he is willing to provide a view for the blog then I'll include this. As is, I think this is a fascinating area that has a long way to run (if you'll pardon the pun) in accounting for how as a species we subjectively experience elation and pain management in relation to endurance exercise. It may also go some way to account for what some people would term 'exercise addiction' and overtraining. In one of my next blogs, my colleague Andy Preston of UEL will write more on psychological coping strategies related to marathon running. As ever, please feel free to comment and feedback on the information I've given you here.

Runners high as motivation
I've been enjoying my running and training in the last fortnight after finally shifting a cold that lingered from Christmas. I can feel the improvement and I've been having good banter with my clubmates at training. I knew I had to put some hill work in today and used Jutland Street behind Piccadilly to get the stamina in the legs. This picture of the hill shoes before and after gentrification but you can see 15 reps of this bad boy would test anyones mettle! Most runners in Manchester know it and you often see others putting themselves through the workout!
Maybe because I needed to let my brain sort out a few things from the last few days (and rarely for me I had music on), but I didn't face this run with the usual trepidation. Maybe due to also having some strength built up in my legs from the last month it wasn't so daunting. By the time I finished and was jogging back home, I did feel the elation I've come to associate with runners high. As a psychologist with an interest in the neuroscience of the brain, I'm curious about the conditions you need to experience this feeling. In my MSc I did explore the idea of trying to do a study to 'induce' runners high in people, but the practicalities of an experiment limited it. I was inspired by a study by Prof Hans Boecker that managed to locate where in the brain runners high was experienced by marathon runners. This was seen via positron emission tomography (PET) scans in an experiment three years ago. But it is very difficult to specify 'if you do x, then y will occur.'
What I can confirm is that I have experienced runners high on a number of occasions, and the feeling of euphoria probably keeps me running - chasing that high when you've had a good session and all the conditions are present to reward the effort exerted. I was quoted for an article by a friend, Monica Shaw, about the subject and I will definitely look to research this in more detail as my career progresses.
In line with what I was writing about motivation for runners during training, I had forgotten about this feeling, as I can get caught up with the chase of improving times and PBs, but as I tell clients/runners, fundamentally you should enjoy your sport/running first, and then it is more likely such experiences will occur and the times will follow. I don't think it is a coincidence that I experienced runners high for the first time in a while after eating good food and having had 10 hours sleep.
What about you? Can any readers cite examples and conditions of when they've properly experienced runners high? What conditions do you think you need in order to experience it? Is runners high a motivation to keep running? Please let me know, I'm interested to hear your experiences.
Overall, if you get a bit sick of running do remember the enjoyment factor! It's easy to forget!

Mental strategies for marathon running - Part 2
In my last entry, I wrote about what Tim had to say on goal setting and how this can be used by athletes to help motivate themselves in training and in race scenarios. Crucially, goals have to be both realistic and achievable. Whilst accepting setbacks will occur, training should condition the athlete mentally and physically to reach the optimal performance level on the day. Tim said the role of coaches and sport psychologists is to help athletes 'get through the emotional, to reach the rational.' This is done by trying to 'control the controllables', which is why process goals are so important as these are under personal control, unlike outcome goals.
Within a marathon event, an athlete will have to confront and deal with fatigue, distractions (from the environment, themselves, and others), pacing and perceived exertion, and boredom and anxiety about negative emotional states. So the role of attention is hugely important. Where the mind is focused moment to moment has been shown to make a big difference in how runners cope with and manage pain.
The two most researched concepts have been i) Internal or external focus, and ii) Association and Disassociation. Internal focus is the process of focusing inward on yourself and your feelings during a run. External focus being the direction of attention to the events around you. Tim's examples of these being mile markers, lamp posts and even other runners backsides! i.e. Anything in the environment that can be seen and used.
Association and disassociation relate to how a person monitors their physiological symptoms. Associating is when you monitor how you physically feel. Disassociation relates to directing your attention away from negative physical symptoms.
During a race your attention will switch between all of these concepts. But using some tricks in training can assist in managing pain, in order to find what works best for you.
Evidence has shown that focussing externally whilst disassociating to be the most effective strategy to delay the onset of 'hitting the wall.' Hitting the wall (or 'bonking' in triathlons) occurs with some people in race conditions when the bodys natural glucose levels are depleted, leading to the body burning its natural fat levels, causing enormous physical and mental discomfort. Tim gave the example of concentrating the mind to choose an object in the envitonment to race towards. This way the race is broken down into smaller chunks. As stated, mile markers can be used to do this, though the relative distance between these can mean that as tiredness bites, you may struggle to 'get through' to the next mile. Focusing the mind to different, closer markers, such as lampposts can be a more effective strategy.
On a 10 mile tempo run this week, I tried this out. I was clocking between 7 and 8 minute mileing and being pushed by faster runners throughout. Taking Tim's advice, I ran 'micro' races to a point no further than 25 metres in the distance. Each time, I would run towards it, in my mind I would say to myself that I'd finished each 'race.' As I passed the object I would repeat the process over again. I have to say, I found this strategy helpful. As the run wore on my quads were aching but this strategy meant it felt like I didn't have so far to go, even though I knew I was tricking myself. It meant I could maintain my speed and not feel so tired. This doesn't work for all though. For Paula Radcliffe, as she passes a mile marker, she counts to 100 to focus her concentration. Others I have researched have 'chunked' London by famous landmarks as they go round the course.
Overall, the most successful runners I have met, regardless of their target finish time, have all managed to re-focus their mind on the race at hand, via a strategy that works for them in order to deflect or manage pain. Sometimes by attending to a discomfort and then trying to minimise it rationally can have quite a powerful effect. Usually I have found people describe how they 'chunk' their current position, i.e. 'I only have to make it to the next drinks station to top up on lucozade to ease the pain I am feeling.'
Tim did mention mindfulness (a buddhist practice of directing attention to present moment experiences and accepting pain as inevitable) as an area researchers are interested in using as a strategy to cope with pain. Mindfulness is thus a series of ongoing negotiations to experience emotions into the present. This is something that hasn't been proved empirically to work so far, but I would be interested to see if it works for anyone. Similarly, I am personally exploring having brief sessions of EMDR to see whether a clinical method can be effective in coping with marathon pain. Eye Movement Desensitization and Reprocessing (EMDR) is a proven clinical treatment, most famously used with victims of PTSD to cope with emotional or distressing experiences. As far as I know it hasn't been adapted to be tried in dealing with marathon pain. I will let you know how that goes in due course, thought I accept it won't be a tool available to most people.
If you have successfully used mental tricks and tips to cope with discomfort, can I ask that you please add a comment below this entry and share it with others. Not all strategies work equally for everyone, but as those who are training for the Paris and London marathons are doing longer weekly runs, it is a good time for you to try out new ideas to see what works. I always remember a mantra an old colleague of mine says to themselves in long races. I like it and I have found it to work before:
"Everyone has to go through this s***! - you won't be the first, and you won't be the last!" Good luck!

Mental strategies for marathon running
Tim started by emphasising that successful marathon running is an exercise in managing pain. The next few entries to this blog will explore this position in more depth. If you are taking part in a distance race it is hoped this advice can help you and you can try some of the tips in training.
During a marathon all runners at some point will experience physical and mental strain and pain. By accepting this and having effective strategies with which to cope can help an athlete achieve their goals for the race. In this and the next blog entry, I'll outline advice to use during training on goal setting to help motivate athletes and how to use coping strategies to reach their potential on race day. Evidence across a range of sports has shown effective goal setting can have a positive impact come race day. On the flip side, unrealistic or poor goal setting has been shown to lead to a runner feeling disappointed with their performance at the finish if they miss their goal/s.
Tim cited Paula Radcliffe, who motivates herself for races by aiming to run faster than she's ever done previously before each race. However, that is only one type of goal that you can use to help you.
Such a goal is described as outcome oriented. In sport, there are 3 kinds of goal that can be set. These are outcome, performance and process goals. An outcome goal is a comparison against another, e.g. "I am going to beat Haile Gebrselassie." For a competitive athlete like Radcliffe, this is a powerful motivating force. However, for the majority of runners in a marathon, aiming to beat a particular foe (or friend!) can be very negative if unfulfilled. Research has shown outcome goals provoke greater anxiety, as they are both uncontrollable and potentially unrealistic - as my example about beating Gebrselassie shows!
What has been shown as healthier to concentrate on are performance and process goals. These are both in the control of the individual. A performance goal is a comparison to an absolute measure. In marathon most often this will be a time an athlete is aiming to achieve. However, these can be unrealistic and can be 'all or nothing' in the mind of the competitor which can lead to anxiety. The best way to use these goals is to use different measures of performance to motivate you for a race situation. So rather than aiming for a 4 hour finish, Tim recommended:
A 'should goal': What you expect to do as a minimum
A 'could goal': When a time comes together (e.g. a personal best)
A 'just might' goal: The ideal scenario
In my case for London I'm aiming to improve on my PB of 3:27. So taking Tim's advice as an example:
My should goal is: 3:30
My could goal is: 3:25
My just might goal is: 3:20
Though my training is going well, I didn't get to do as much pre-training before Christmas, so I'm being realistic with my goal setting. If I finish with 3:29:59 then I'll be happy, despite this being slower than my PB - given my conditioning. Beyond that, my satisfaction will increase with every minute I take off that finish time.
To reach these performance goals, an athlete can enhance their running with process goals. These are specific aspects of your overall performance that fall under individual control. Your posture, cadence, strategies for dealing with fatigue (e.g. attention), pacing and building up mental strength can all be practiced and built up through training.
Given the 3 months required to train, not only should you try and work at your speed, distance and physical conditioning, training runs should be used to sharpen up mental strategies in preparation for race day. If you've prepared well mentally through training, come race day, whatever scenario might occur (from bad weather, to other runners, having a 'bad day' in the race, physical discomfort or whatever), you have a repertoire that can be drawn upon.
In my entry tomorrow, I will outline specific mental strategies you can implement as your weekly mileage goes up, to help you get to an optimal level of performance come race day.

What is the difference between Sport Psychology & Coaching?
Over time I've refined what I write to cover sport psychology concepts and advice about coaching - tied into my experience as I've developed my practice with athletes in both fields. Crucially (and wrongly) I've taken for granted that everyone who reads this understands what I'm talking about!
So, to be absolutely clear, I'm going to use this post to define both, explain the similarities and differences between the disciplines and where the work of the two professions overlaps. I've shot an interview with Dr Tim Holder of St Mary's University in which he explains how the work of sport psychologists has altered working with coaches over the last 20 years in the United Kingdom.
But first, the definitions.
What does an athletics coach do? According to the good people at Wikipedia, Coaching:
"...is the practice of supporting an individual, referred to as a client, through the process of achieving a specific personal or professional result." I had to use this definition, for when I looked at the UKA website (the body who administers coaching in the UK), it didn't have a definition I could use here!
What does a Sport Psychologist do? and how does this differ to coaching? One of my heroes in the field, Dr Mark Anderson of Victoria University (AU) says in his book'Doing Sport Psychology (Chapter 1 p.6):
“My job is to talk to athletes about how things are going for them to see if there are ways we can work together to make their athletic involvement more enjoyable...to help with some of the mental aspects of training and competition.” Not much different from a coach right? Indeed, Doherty (1976) says “Not all the successful coaches I have known have been effective teachers of techniques, but with no exceptions, all have been effective on this human side of the coaching coin.” But coaches have to do more than teach techniques. They have to motivate their athletes, build team cohesion, goal set, and assist in things that are clearly psychological (Brewer, 2000).
As Anderson and Brewer point out though, coaches have to be careful being sport psychologists as there may be a conflict of interest if they are simultaneously trying to help for both performance and clinical reasons. That is not to say that sport psychologists work solely on clinical issues (e.g. recovering from injury, retiring from competition, overcoming eating disorders, dealing with depressed or anxious athletes), though some do. More that coaches can't cover everything that their multidisciplinary role requires – e.g. they can advise on stretching/warm up as a physio would, but a physio can advise in greater depth as part of a multi-disciplinary coaching team. Ergo, a good sport psychologist can get to know an athlete in more depth about their motivation, their mental strength, anxieties and goals in a way a coach may not be able to.
In short, Anderson advocates letting coaches get on with enhancing their relationship with an athlete to aid their performance and achieve their 'overall coaching objectives', and allow access for sport psychologists to work with athletes to help the athlete understand about themselves and their (mental) strengths, enhance their mental skills, and where necessary, intervene in clinical issues as anyone would in a 'normal' therapeutic relationship.
The British Psychological Society (the organisation with whom I am an accredited probationary sport psychologist) outlines the following ways in which sport psychologists work: "Sport psychologists work with individuals, teams, and organisations in a wide range of contexts including:"
- Helping elite performers to develop preparation strategies to deal with the demands of competition and training
- Applying research into motor learning and psychophysiological processes to maximise practice and fitness regimes
- Assisting coaches, managers, and referees with enhancing their interpersonal and communication skills
- Counselling injured athletes during their rehabilitation
Where do sport psychologists do their work? "Some sport psychologists work as private consultants, or hold full-time positions with professional sports teams or national governing bodies of sport, but most combine their consultancy work with teaching and research in University departments." This is the area in which I am trying to move in my career.
To give you an example of what a 'real' sport psychologist does, I was kindly helped by Tim Holder of St Mary's University, who explained how the relationship between sport psychologists and coaches has developed over the last 20 years in the UK. I also asked him how the field is changing and what he is doing with the Endurance Performance and coaching centre at St Mary's University.
The goal of the centre is to "create a performance environment within which athletes are able to live and train together in high quality groups, whilst also offering a variety of educational opportunities.” At St Mary's student athletes train alongside international level athletes who use the facilities as their training base train and obtain support from coaches, nutritionists, sport psychologists, bio-mechanists and physiologists. Thus a multi-disciplinary team can help optimise the whole athletic experience. This is an approach that is on the increase, as described by Alberto Salazar with the US endurance teams use of a sport science team in the US's training for major competition.
Tim gives some interesting insights into the work he has done and how the work of coaches and sport psychologists has evolved. [Forgive the filming squashing Tim into the middle of the screen - this was my first attempt at filming via a phone for the blog!]. Afterwards I asked Tim, "Whats your view on Sport Psychologists conducting coaching as well? What warnings, from experience, would you give?"
Tim Holder: "From my experience sport psychologists can bring a great deal to a coaching situation particularly if they have a skill acquisition background as well. The only issue that can emerge is if you have a dual role as coach and sport psychologist - it is important then to be clear as to which role you are in (or which hat you are wearing) as expectations and responsibilities are clearly different."
This agrees with Mark Anderson's view, particularly for the sport psychologist who also coaches. Personally, I have spent the last six months coaching using some sport psychology techniques in the process (mainly addressing anxiety issues in athletes, and working on athlete confidence and preparation for competition). This is partly because I have been in training for coaching qualifications. Also I have been learning under the tutelage of head coaches at an athletics club and my role has been to support them coaching. Within this work (using the experience I have from my sport psychology training) I bring the appropriate level of psychology to enhance athlete performance. But fundamentally what I bring to all my work with clients, and at the core of my work, is care for the athlete. This covers the approach you take with the person, how you view them and their athletic potential, and ensuring that confidentiality and insurance are adhered to.
In the next blog I will be passing on advice from Tim to endurance runners (predominantly, but not exclusively around marathon) from the UKA open day about mental strategies to help in training and races. I hope you found this post helpful and I welcome any questions or feedback.

UKA Training Tips for Marathons - St Mary's Uni 30/1/2011
Speaker: Mick Woods (UKA Endurance Performance Coach to Stephanie Twell and Charlie Purdue)
Throughout Mick emphasised the importance of preparation for the marathon event, from the beginning of training, to the day itself. Having competed in over 70 marathons himself, including the first ever London Marathon in 1981, he had experience as both a coach and as a runner.
Mick emphasised the need for Marathon runners to have an endurance base from which to build. In an ideal situation, you will have a good 6 months of running before the day of your marathon. The building of a base level occurs by running increasing distances over 3 months prior to starting marathon training. Ideally this then leads straight into the beginning of the 16 week Marathon training cycle. At the beginning of the 16 week build up to the Marathon event, you should add in more speedwork than you have been doing already.
If you have run a marathon in the previous year, your body will have adapted so that you won't have to go back to the same training plan and level of mileage/effort that you did previously. At the 3 month point (16 weeks before race day) you should begin your full plan, the likes of which can be found online and in Runners World.
We were then shown a chart devised by Jeff Galloway (1981) which Mick deemed the most accurate guide to the amount of weekly miles an athlete should be completing to reach a desired target time in the 16 week cycle:
3 hours - 45 to 55 miles/week
3 hours 10 - 40 to 50 miles/week
3 hours 20 - 38 to 48 miles/week
3 hours 30 - 35 to 45 miles/week
4 hours - 30 to 40 miles/week
So: In the case of a runner aiming for 3 hours 30, they should start their first of 16 weeks at around the 30 miles per week total mileage, and then build up to covering just over 45 in their biggest week. For all, the longest run should be about 25% of your total mileage. Before anyone says anything, I know this means that if our 3 hour 30 runner did 22 miles as their longest run, in theory this would mean they would cover 88 miles in total! Obviously this shouldn't be attempted. Instead, the role of quality running was emphasised, and so (in this case) the other 27 miles should be made up of speed/tempo work, maybe a hill run, and a steady run. Certainly by the time of taper core work should be much more prominent than at week 1 of the cycle. See my blog post for Alberto Salazar's views of using weights during marathon training.
Mick then gave us the golden answer to a question I'm often asked as a coach.
"At what speed should I run my long runs?!'
Answer: You should maintain a steady pace throughout and run 30 to 60 seconds SLOWER than your target time marathon pace.
e.g. If you want 3 hours 30, you need to run 8 minute miles in the race. In your long runs you should keep your speed between 8.5 and 9 minute mileing.
I'll put my hand up and say that for the last year I have been running my long runs at the same speed I race. This year I will follow this advice. However, in the last half hour, see if you can up your speed on a regular basis. I am also ignoring my new coaches advice to only run for 2 hours maximum prior to race day. I think it a foolish approach in retrospect.
"How long should your longest run (of the whole 16 weeks) be?"
Answer: About as long as your intended time (with a margin taken off).
e.g. If you are aiming for 3.20, you should run for about 3 hours on your longest run. Use this as a guide for your longest training runs. The importance of the time on your feet is that you should fully experience the physical and mental conditions of what it feels like for that length of time near to the race (however experienced you may be). Once you've done your longest run, then really really rest in your taper!
Many examples were given of good runners who couldn't resist the urge, with all their training under their belts, and with their engines 'revving', going out and either doing too long a run in the 3 week taper, or too fast in a speed session during this rest time.
A few extra tips:
Throughout training:
1) Monitor your weight. If you lose a lot, then you may be depleting your glycogen levels which you will need to ease past to 'the wall' in the race.
2) Make sure you take iron, vitamins C and D supplements - particularly in the taper as your immune system will be recovering from your max milling the week before and thus susceptible to sniffles/illness.
3) Within your 20 mile runs, include at least 1 race.
If you are over 3 hours in your projected time, aim to run your 20 mile race at just under marathon pace but faster than your normal long run. If you feel comfortable and able to in a 20 mile race, go at marathon pace in the last 20 to 30 minutes to build in speed as well as stamina.
If you are sub 3 hours, aim to run it just a bit faster than marathon pace.
