Shining a light on ‘the dark side of running'

A response to our 'Minds run free' cover feature.

12 May 2017

As avid runners and practitioners working in sport and exercise psychology, we were immediately drawn to the ‘Minds run free’ article by Christian Jarrett and Ella Rhodes in The Psychologist (May, 2017). The article provided readers with an interesting insight into the psychology of why people start to and continue to run. In particular, sections on ‘How do runners keep going’ and ‘The dark side of running’ stimulated much deliberation, closely aligning with research we are conducting at Staffordshire University.

As Jarrett and Rhodes emphasise, even though the psychological benefits of exercise are established, there lies a darker paradox that requires closer inspection. Here, the benefits of running (e.g. enhanced mood and self-esteem) may in some cases have psychological and physical implications (exercise dependence, eating disorders). To better understand this paradox, we draw upon rational emotive behaviour therapy (REBT), which is based on the Epictetus’ premise that ‘people are disturbed not by things, but by the views they take of them’. In REBT, these ‘views’ are encapsulated by the concepts of rational beliefs and irrational beliefs. Rational beliefs are non-extreme, flexible and logical, and lead to healthy emotional and behavioural responses to adversity. In contrast, irrational beliefs are extreme, rigid and illogical, leading to unhealthy emotional and behavioural responses.

In many of the athletes we have worked with, irrational beliefs often lead to maladaptive responses to setbacks, injury, rejection and failure. From our experience and research, in the face of factors prohibiting an individual’s ability to exercise, there are four main irrational beliefs that often underlie psychological distress:

  • Demandingness: ‘I want to, and therefore I must exercise’
  • Awfulising: ‘It would be terrible if I could not exercise’
  • Self-depreciation: ‘Not being able to exercise makes me a complete loser’
  • Frustration intolerance: ‘I can’t stand it when I don’t exercise’

When those dependent on running miss an opportunity to do so, their irrational beliefs (e.g. ‘I would like to run therefore I must, I can’t stand missing a run and it is terrible if I did’) result in unhealthy cognitions (‘I hate myself for not running’), emotions (e.g. anxiety, guilt) and behaviours (e.g. undereating).

In the high-performance athletes we have worked with, irrational beliefs, despite their maladaptive consequences, ironically can acutely provide the impetus and dogged determination for runners to withstand and tolerate the physical and psychological demands of running (training or competing). Indeed, for a runner during the deepest and most challenging moments of a race, an extreme, evocative and dogmatic belief such as ‘I must not fail, and I’m a loser if I do’ may provide a functional stimulus to continue no matter the cost (pain, injury).

However, what are the costs of such beliefs, and do the potential acute performance benefits outweigh the costs? On the Smarter Thinking Project blog, Martin Turner refers to the old story of Damocles and King Dionysius, drawing comparisons between irrational beliefs and the sword of Damocles (see There are also many accounts whereby extreme and dogged irrational beliefs come at the cost of runners’ physical health. Here runners may push their bodies beyond exhaustion during a race or overtrain – commonly associated with burnout (chronic physical and emotional exhaustion). Runners lose sight of personal wellbeing in the pursuit of personal success.

We do not wish to cast a dark shadow over what is undoubtedly a healthy and meaningful pursuit for millions; rather, considering the detrimental effects of irrational beliefs on psychological distress, we urge runners to keep a close eye on the relationship they have with running. Ensuring the lacing-up process is driven by a healthy preference rather than a dogmatic demand to run.
