Feb. 11, 2012, was my first trail ultramarathon. The Psycho Wyco Run Toto Run 50K in Kansas had single-digit temperatures and below-zero wind chills at the start. It was the coldest ultra I ever ran.

Until last weekend.

One hundred and sixty-one miles.

It has been years since I’ve had a month like that. I’m talking pre-Strava, DailyMile stat tracking days. But that was my January running effort: 161 miles.
