In-House Fundraiser @ CrossFit O'Fallon

The CFO team will be hosting a fun in-house competition from 8-11am.  The cost is $10 per athlete to compete.

Don’t be afraid to participate, we will be doing a partner WOD mash up. No more volume than you would do in a normal Saturday workout. It will be a team competition, draft style – everyone’s name in a hat and we draw them out.

Just a fun time to build community and help support the CFO Regionals Team!
