Last weekend, professional runner Johnny Gregorek became the second American ever to run an indoor mile in less than three minutes and fifty seconds. His final time of 3:49:90, completed at the pro portion of a collegiate conference at Boston University, clocks out to about 15.65 mph — insanely speedy — bringing him just .09 seconds behind the fastest indoor mile by an American man and 6th in line for fastest indoor mile in the world. The World Record was earned by Ethiopian Yamif Kejelcha the same race last week in Boston when he ran a 3:47:01. For reference, the fastest mile ever run was a 3:43:13, completed outdoors.
Gregorek, an Asics runner, ran for the Columbia University and the University of Oregon (home of the famous Hayward Field, where the 2020 Olympic Trials for Track and Field will be) until 2015, when he graduated. His dad, John Gregorek Sr., was a two-time Olympian in the 5000-meters and his mom, Christine Gregorek, is a two-time NCAA champion.
“After a race, if it went well, I will treat myself to something [like] burgers, fries, a beer,” Gregorek says. “Recovery for me usually involves getting a good meal in me, sleeping well and running very easy for a day or two after. After that mile, I immediately had dinner with friends and then tried to get a good night sleep. It can be a challenge after getting so much adrenaline going. Now I’m still just jogging around easy because it’s my downtime for a week or two.”
Since it was Gregorek’s final indoor run for the season, we chatted with him to find out what gear he finds most pivotal in his post-race recovery.
Polar M430

Monitoring your heart rate after a race is a great way to keep track of your fitness level — the faster your number returns to normal, the better. Gregorek uses his Polar M430 all the time. “It tracks my heart rate, and I’ll check in on that on easy days to make sure I’m keeping it low and recovering,” he says. Everyone’s resting heart rate is different, but ideally, you’re seeing lower numbers on your days off than when you’re in the middle of a HIIT workout.
