HOKA Kodiak Ultra Marathons by UTMB

HOKA Kodiak Ultra Marathons by UTMB is a multi-day trail running event in Big Bear Lake, California, held from 8 October to 11 October 2026. The event uses trails around Big Bear Lake and passes landmarks such as Sugarloaf Mountain and Siberia Canyon. The courses move through three climate zones: high desert, sub alpine, and semi-arid, and feature lake views from multiple points.

Distances offered include:

  • 100M (162 km) - 4850 m+ elevation, 8 Running Stones
  • 100K (99 km) - 3120 m+ elevation, 6 Running Stones
  • 50K (48.4 km) - 1339 m+ elevation, 4 Running Stones
  • 21K (19.5 km) - 575 m+ elevation, 2 Running Stones
  • 10K (10.5 km) - 280 m+ elevation

The 2026 edition is the UTMB World Series Americas Major. Runners at this Major collect double the Running Stones compared to other UTMB World Series events for the UTMB World Series Finals lottery. Each Major grants automatic qualification to 210 runners for the 2027 UTMB World Series Finals, including age-group winners and the top ten men and women in the 100M, 100K, and 50K categories.

The event also runs a festival in downtown Big Bear Lake with food vendors, a DJ, a parade, and activities for support crews. UTMB Community Bibs are available, with part of the funds supporting local charities and trail stewardship via the IRONMAN Foundation.
