Throughout the year, 14 races come together to make up the Commanding Officer’s Semper Fit Series. Run along the shoreline of the Pacific Ocean, up mountainous terrain, and even through swampy waters, the challenge is always new and exciting. Run one or run them all, it’s something you’ll never forget! The Commanding Officer’s Series is open to the public.

Frequent Racer Program

In the hopes of recognizing our frequent racers we have developed the MCBH Frequent Racer Card program. This program will allow participants to earn a custom MCBH medal for participating in 7 out of 11 races. This includes races that offer team categories such as our sprint triathlons, biathlon, BOAR run and/or 10K formation run. Frequent racer cards can be picked up at the registration tents at our events. For questions please email the Race Coordinator or call 808-254-7590.
