The 8th annual Kodiak Ultra Marathons will take place September 9-13, 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 50-mile distance and a 50K, which will be run along the same track as the 100-mile race. New in 2020 - Half Marathon and 10K races.

We will host an elite field for the 100M and Half Marathon races on September 11-12, 2020 in Big Bear Lake, CA. The 100M race will start at 6PM on Friday, September 11 and the Half Marathon will start on Saturday, September 12. The maximum capacity in each race will be up to 80 runners - 40 men and 40 women that meet qualifying standards. There is a prize purse of $22,800 in total, as part of the Spartan Trail World Championship.

In addition to the Elite Race, we will offer an Open Course race, an option for those adventurous runners out there looking to get out and run in a mostly self-supported environment, while racing toward an official finish time. The course will be marked, but there will be no formal aid stations. The ultra distances will require your own crew support. We’re excited to set up this unique format in this unique year. 

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

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 2020 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.
