The Kodiak Ultra Marathons by UTMB 100 Mile course makes a complete loop that circumnavigates Big Bear Lake.

The Kodiak Ultra Marathons by UTMB® is a dream course with a lively Start and Finish downtown in The Village of Big Bear Lake. Runners will make a complete loop to circumnavigate the entire Big Bear Valley.

The first 50k concludes with a visit through the rarely crossed Siberia Canyon, followed by lots of cruisers along the north shore of Big Bear Lake, including over 20 miles of the Pacific Crest Trail. The real test will come in the second half where runners cross over Deadman’s Ridge and then summit Sugarloaf Mountain at nearly 10,000 ft. Finally, enjoy the cruise down Knickerbocker Road to finish downtown in the village. This is a true mountain 100-miler, with some technical footing and a lot of running above 7,000 ft.
