About Kodiak 50K

Kodiak 50K is the 48.0km trail race at HOKA Kodiak Ultra Marathons by UTMB 2025 (Big Bear Lake, United States). The race starts on October 8, 2025.

Race strategy

Run the climb at race pace, build your speed on the downhill, and go all out at the finish.

  • Start easy and control your HR up to Snow Summit.
  • Hold your race pace up to 42.8km, but stay in control.
  • Ease into the early runnable section, then run your race pace, and go all out on the final descent from 42.8km.
  • Start · 0.0km–1.5km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.5km–9.9km · Plus 1 more climb. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
  • Work · 9.9km–42.8km · 32.9km of runnable trail, high point 2491m. This is where the race is built: steady, solid effort. Running pays off here: run wherever you can.
  • Home · 42.8km–45.8km · Descent of 234m averaging 8%. No heroics: settle back into your own effort and hold it to the line. Long descent: keep it even and let go only near the end.
