Join Kodiak Ultra Marathons

The San Bernardino Mountains are a high and rugged mountain range in Southern California in the United States. Situated north and northeast of San Bernardino and spanning two California counties, the range tops out at 11,489 feet (3,502 m) at San Gorgonio Mountain, the tallest peak in all of Southern California. The San Bernardinos form a significant region of wilderness and are popular for hiking and skiing. The mountains were formed about eleven million years ago by tectonic activity along the San Andreas Fault, and are still actively rising. Many local rivers originate in the range, which receives significantly more precipitation than the surrounding desert. The range’s unique and varying environment allows it to maintain some of the greatest biodiversity in the state. For over 10,000 years, the San Bernardinos and their surrounds have been inhabited by indigenous peoples, who used the mountains as a summer hunting ground.

The 4th Annual Kodiak 100 Ultra Marathon presented by CarboPro is situated in the San Bernardino Mountains of Southern California at an elevation of 7,000 feet. The cozy, cool, alpine village of Big Bear Lake is ready to host you and your crew. This course is the much anticipated complete loop around the entire Big Bear Valley with the most grand vistas and best climate you could ask for in an ultra. New for 2016, the course will be run in opposite direction (clockwise) around the lake. With nearly 17,000′ of vertical climbing and sustained running over 7,000′ in elevation, this course will challenge the best ultra runners on the planet. This is not your typical So Cal Ultra. The Kodiak is a true mountain hundred miler. The perfect mix of technical, steep climbs to 10,000′ summits, and a few runnable sections peppered in. Flowing single track. Epic canyon passages. Huge climbs. Welcome to the mountains.

Course Highlights

The Kodiak 100 Ultra Marathon is a dream course with a lively Start and Finish downtown in The Village of Big Bear Lake. Runners will circumnavigate the entire Big Bear Valley including a visit to the summit of Sugarloaf Mountain (9,963′) and a trip through the rarely visited Siberia Creek Canyon. This is a true mountain 100 miler, with technical footing and a lot of running above 7,000′.
