The first-person: I. The will, the self, the subject of the experience of all those miles all those miles all those mornings all those trails all those routes all those repeats all those shoes all those blisters all those recoveries all those stretches all those runs. The experience of running is always private.

The holy running trinity of body, mind, and soul—unified not in every run but in enough runs.

Minutes. Likely not for you.

Miles they say a pair of running shoes is good for. (If you’ve been running in the same pair since 2009 and feel fine, don’t sweat it.)
