Nothing to race. Everything to try.

Open Season

The race calendar is empty, the evenings are getting darker, and for once, nobody’s telling you what comes next. That’s not a gap in your year. It might be the best part of it.

This is when you do the work there’s never time for during race season: long, easy miles that build the engine you’ll run on in spring, jumps and bounds that put the spring back in your legs, and that first Hyrox session you’ve been curious about all year.

It’s also a season for moving without a plan, just to see where it takes you, in your body and in your head. So go explore. Everything’s in season.
