It is reassuring to get some perspective based on some well-told personal experience.
My gut feeling is that some athletes out there (with or without coach guidance,) especially young ones, confuse "courage" with being "wreckless"; "self-awareness" with "excessive caution," or maybe even "cowardice."
A "race" or "sporting event" with a "conquest" or "life-threatening battle."
I am in no way negating the inherent risk with elite sporting activities. No less in running, where according to the NYT article posted on this board the number of deaths seems to me phenomenally high (and absurdly related to Healthcare costs!!)
But in a healthy mind, in a healthy athlete, that's all it should be: inherent risk. Not a desired death-wish of sorts.
Sort of like Free Climbing: apart from showmanship, there is no reason why you can't do exactly the same difficult slope, the same athletic climb without a safety buckle. You are stil free climbing. The difference is if you slip, and slip you can, you hang in mid air and do not fall and die.
As another poster wrote, I would also tend to associate excessive suffering with poor training and not with lack of character or sense of purpose. Beyond the elementary principles of supercompensation, there is infinite research indicating that rest is fundamental; it is part of training. It is part of getting stronger, better, faster. The body needs to recover. The mind needs to recover. Yes it will cost time. But this will only seem expensive to the insecure; to those who fear ageing, to those who fear the passing of Time. It, in reality, should be an investment for good days to come.
Good athletes need rest and nourishment. And i can't imagine that some emotional support would not be appreciated. Now, keep in mind that if you grew up poor in Kenya or Ethiopia, rest might mean only walking 5 miles to school instead of the usual 12. And not slacking on the couch. And good nourishment could be an extra bowl of milimili and some canned meat. Not pigging out on your favorite food because you know you are going to run it off.
While the sink-or-swim, kill-or-be-killed, conquer-or-be- enslaved could very well seem to be useful on military battlefields, does it work in Sports? Running? Professional or otherwise?
I sense too many talented people giving up. Too many others discouraged at the outset to even develop an interest. Too many talented individuals getting injured and losing motivation. Does it make sense? And all things considered, some might say way too many casualties...
