Multi-marathoners and the 100-Marathon Clubs
For many, the marathon is the ultimate sporting challenge. But what happens when you run not just one, but dozens or even hundreds of them? This pursuit of marathons is internationally supported by the existence of more than 30 national associations of 100-Marathon Clubs. These groups provide a structure that offers guidance, rules, and recognition of milestones such as reaching 100, 200, or more marathons. They also support the organization of events that go beyond a single race, such as bi, tri, quad, and even 10-in-10 or 20-in-20 marathons.
A recent study analyzed the mental health of 576 runners from these so‑called “100‑Marathon Clubs” (56% men, 44% women). These multi‑marathoners had completed an average of 146 marathons, with a mean age of 53.4 years.
More kilometers, more problems?
Although exercise is usually associated with psychological benefits, the results were surprising. Multi‑marathoners showed more symptoms of depression and anxiety than the general population of the same age, although in most cases without reaching clinical levels. However, 8% fell within the range of severe depression and high anxiety – a percentage higher than that found in the general population.
Age and gender influence
Older multi‑marathoners reported lower levels of anxiety and depression than younger runners, possibly because experience and perspective help them put challenges into context.
As for gender, female multi‑marathoners scored higher on depression than men, which aligns with trends in the non‑running general population. Anxiety levels, however, were similar between men and women.
Psychological profiles
The analysis identified four “types” of runners:
- Stable (33%): very low levels of anxiety and depression.
- Mild symptoms (41%): some dissatisfaction, but no major issues.
- Intermediate (18%): moderate and fluctuating symptoms.
- Critical group (8%): severe depression and anxiety, above clinical thresholds.
The data found are shown in the table below.
Notably, the group with the highest anxiety and depression symptoms (Class 3( was, curiously, the one with the greatest number of marathons: 279.
Conclusions
- Multi‑marathoners, despite the image of strength they can project, are not immune to sadness, apathy, or worry.
- Not everyone who runs 100 marathons feels equally: while the majority enjoy it, a small group experiences serious psychological difficulties.
- The multi‑marathoner is fertile ground for anxiety, overtraining, or exercise addiction.
- Just as we take care of physical recovery, we should pay equal attention to psychological recovery: rest, social support, and, if necessary, seeking professional help.
In short:
The challenge of reaching the 100‑marathon barrier is an epic adventure that can bring out both the best and the worst in each of us. The key is to listen not only to the body but also to the mind, and to run not just to add up races, but to enjoy the journey.
