The HOKA Kodiak Ultra Marathons by UTMB® showcases Big Bear’s Holcomb Valley and Baldwin Lake areas. From the alpine forest with towering pines to the high desert with Joshua trees, you’ll experience several climates and varying vistas from the mountains to Big Bear Lake. The Holcomb Valley has a rich history that began when gold was discovered for the very first time in Southern California in 1860. The course will be a combination of beautiful singletrack and forest service roads. Lots of views of Big Bear Lake and the surrounding San Bernardino National Forest. While running through Holcomb Valley you will be between 7,000-8,000ft in altitude. Come prepared for a temperature swing from the high of the day to the low of the night that span up to 40 degrees F (20 degrees C).
