I’ve found that if I decide I’m only going to run two miles, I’ll struggle at the end of those two miles, but if I decide to run four miles, I won’t start struggling until I get close to the fourth mile. This tells me I sometimes hold back, and that I’m often capable of more. It helps me employ more mental grit during my runs. It probably also means I’m capable of using that grit to resist the siren song of anything made of dark chocolate or goat cheese, but let’s not get ahead of ourselves.
