“ It can't be more than a quarter of a mile to the finish, but it seems to go on forever. Do I really have to do this? My legs are entirely dead. Would it really matter if I stopped here?But I know I'd regret it if I did, so I plod leadenly on, distracting myself...with the thought that, whatever troubles I may have been carrying around in my head before the race, I have now entirely forgotten what they were. This thought is rather refreshing. Whatever physical pains it has involved, this ordeal has utterly absorbed me, forcing my brain to focus on the kind of concerns for which it evolved - navigation, survival, balance, digging deep - rather than on the fretful urban anxieties to which it has become habituated. Reconnecting with your inner animal, I suppose you could call it; and it feels good. Especially when, blissfully, I catch sight of the finish. ”
