Kodiak Ultra Marathons is a premier event of Open Air Big Bear, a non-profit organization with the mission to advance and celebrate outdoor sporting events and activities in Big Bear Lake.


Thanks to our sponsors:

The 7th annual Kodiak Ultra Marathons will take place August 16-18, 2019 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 50-mile distance and a 50K, which will be run along the same track as the 100-mile race. The 100 miler will start at 6PM Friday (that's right - a night start!). The 50 miler will start at 4AM on Saturday on Holcomb Valley Road near Lake Baldwin, and finally the Back 50K will start at 6AM am at the base of Sugarloaf Mountain.

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.

Proceeds from the Kodiak benefit the San Bernardino Search & Rescue, Big Bear Valley Trails Foundation, Mountain Top Radio Association, and the Big Bear Middle School Interact Club.

NOTE-ITRA has changed their scale in 2019


To qualify to start the 100 mile race you must have completed a minimum of a 50 mile race distance within the races' official cut-off time, within the last 2 years. You can finish a 50M race at anytime before the 2019 Kodiak 100. (You MAY register now and complete your qualifier later. If you do not complete your qualifier, you will be downgraded to the 50M race). Alternatives to the 50-mile race finish will be considered - you must email us! All participants must use good judgment as to their fitness level for this event. You must be sufficiently prepared for all trail and environmental conditions. These are tough mountain courses that should not be underestimated!


Big Bear is located at 7,000ft and has a "high desert" climate. This means warm to hot days with cool and cold nights. The sun is strong up here! Typical temperatures during this time of year are highs in the low 80s and lows in the high 40s. A temperature swing of 30-40 degrees is not uncommon. The course has many exposed sections with little shade. When the sun drops below the ridge, you'll experience the temperature change in less than an hour. Come prepared for all conditions.
