| hsrob said: Ironman triathlon (4km swim, 180km on a bike and a marathon back to back). It doesn't require concentration in the same way that Formula 1 does, but the amount of mental toughness, not to mention physical conditioning required is astounding to me. |
Ironically, Jenson Button, an F1 driver, participates in triathlons.
