Mr. Hall has ran a lot of marathons, in fact one was sub 2:05.
Mr. Krupicka has ran a lot of 100 mile races, in fact he has ran at least one, that I read of, sub 15 hours.
This post is about something, from reading their writings and listening to YouTube videos, that I think they have in common.
Both made changes, for health reasons as I understand it.
Mr. Hall still runs some, but he has become a weight lifter.
Mr. Krupicka still runs, but also skis, climbs and bikes.
The point is, it sounds like they didn’t stop, they shifted to something else, but they keep going. I admire that in both of these men.
