Description

Get ready for a functional fitness challenge built for all abilities.

Cerox is back, and this time, there’s no running. Just pure work.

You’ll take on 8 fitness zones designed to test your endurance, strength, and grit. Choose your level of challenge:

Cerox Iron:  The same zones as the classic Cerox event, but without the running.
Cerox Iron X: Twice the grind, none of the miles. Double the reps, double the work.

You can sign up as an individual or with a partner team. Teams can divide the zone work however they choose.

Estimated Wave Time:

11 AM: Iron X Individual

12 PM: Iron Individual

1 PM: Iron X Teams

2 PM: Iron Teams

Get your tickets now and be part of the action on November 15th!
