The 9th annual Kodiak Ultra Marathons will take place August 20-21, 2021 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.

There will be a total of 13 aid station stops along the 100 mile route, including six crew-accessible aid stations. Pacers are permitted starting at Mile 55.8. Pacers permitted in the 100M race only. Visit Big Bear has generously granted the Kodiak a $10,000 prize purse! The Kodiak 100 miler is a 6 point UTMB Qualifier, while the Kodiak 100K is a 4 point UTMB qualifier. The Half Marathon will score you 1 UTMB point! 

New in 2021! The addition of 100K, Half Marathon, and 10K courses.


Want a taste of the Kodiak without the extremes of summiting the 10,000ft Sugarloaf Mountain and crossing over Deadman's Ridge? Or maybe you just want to avoid the climb up Seven Oaks. The 100K will start with the 100M race from the Big Bear Village and follow the same course all the way to Mile 59. 

Half Marathon & 10K

Start and finish downtown in the heart of the Big Bear Village. You will head into the forest and start climbing to the high point of the course at 8,000 feet. Enjoy the beautiful single track along the ridge, with amazing views of San Gorgonio peak in the background! A stunning course that will test you and thrill you at the same time. The final 3 miles are a cruise downhill along Knickerbocker Road, a dirt road above the town of Big Bear Lake with view of the lake to take in while you finish your trail run.

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 2021 Kodiak 100. (You MAY register now and complete your qualifier later. If you do not complete your qualifier, you will be downgraded to the 100K race). Alternatives to the 50-mile race finish will be considered - you must email us! There is no specific qualifier for the 100K race, however we highly recommend having completed at minimum a mountain 50K race. 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 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.

Kodiak 100K Finish Line

Cushenbury: Highway 18 & PCT


Note: Runners are responsible to arrange their transportation from the 100K finish line. There will be no shuttle service.

**If you are a solo runner and don’t have a planned ride back to the Start area, don’t worry. We have a wonderful runner community where we don’t leave anyone behind. If you finish and don’t get connected with another runner returning back to the Start around the same time, we will make sure no 100k finishers are left behind! We have a fully stocked aid station and finish line full of volunteers eager to help out. We do recommend putting some dry, warm layers in a drop back for Cushenbury if you may be hanging out for a little while.
