Sometimes I finish a really long run or a strenuous hike and think that I’ve exhausted myself to my very limits and can’t push anymore. And that might be true because once I wildly underestimated the amount of water I would need on a 10-mile hike and considered drinking from a (not so clean) stream at the end. That was miserable.
But I like to push myself and see what I am capable of, and doing that is a long process of learning and failing and eventually succeeding. I found some articles about some unbelievable races that are designed to push humans to their very limits.
As cool as it would be to participate in one of these, I think I’ll stick with my shorter races. But who knows?
