This might simply be a commentary on a concept that most understand well, but in my humble opinion it bears reiterating from time to time...
I think one of the simple joys that ultrarunning allows us is a typical willingness to do stuff.
(I know.... "doing stuff" is a far too specific and technical term...)
Albeit indirect in most cases, something about an intentionally trained ability to rise to the occasion is a necessarily versatile quality.
This was illustrated to me in a running situation on Sunday; I had run a half (don't laugh...) that morning, and while eating afterward, when a friend mentioned wanting to go for "12 or so miles" that afternoon, I didn't even have to think twice (even with ulterior motives aside...).
Obviously, this example is a direct effect of the distance-running-specific training, but after contemplating it a bit further, it seems that we can extrapolate quite a bit from such training.
Just think of the last time a friend or family member asked you to come along for something outside your normal routine. What might have been an intimidating prospect to most was just "something else" or "something new" for you.
I also think it goes beyond the oft-mentioned dictum of "Well if I can run XXXXXX Epic Race/Run/Event, then I can do anything..."
I think it's more of a newfound outlook than a comparative look back.
Yes, success breeds success, but with the type of sport we're in, seeking out that next challenge or simply taking the blows as they come is ingrained in us.
This is something we all innately comprehend, but perhaps it's worth thinking about from time to time. It's got some pretty cool implications...
