Cold Weather Club

I’m a year-round outdoor runner, but this winter has really tested my resilience. I’ve been itching to try out the Mile High Run Club in Nolita, a studio that offers treadmill classes, and now it has an enticing new offering: the Ultra class, a 90-minute mix of endurance, interval and form-focused running, aimed at people preparing for a half-marathon or longer distance race. No more excuses!
