About Kodiak Ultra Marathons

The 8th annual Kodiak Ultra Marathons will take place August 14-15, 2020 in beautiful Big Bear Lake, California. Big Bear Lake sits at 7,000 ft in the San Bernardino Mountains of Southern California. The 100 mile distance will start and finish in the Big Bear Village and will circumnavigate the entire Big Bear Valley. The Kodiak also offers a 50M, 50K, Half Marathon, and 10K.

There will be six crew-accessible aid stations along the Kodiak 100 mile route, including the start/finish area in the Village. Pacers are permitted starting at Mile 55.8. No pacers in the 50M or 50K race.

We encourage all spectators to enjoy the start/finish area in the Village. We will have a beer garden, food and sponsor booths setup on Saturday. Bring your friends, family, kids...
