About Kodiak 10K

Kodiak 10K is the 10.0km trail race at HOKA Kodiak Ultra Marathons by UTMB 2025 (Big Bear Lake, United States). The race starts on October 10, 2025.

Race strategy

Short race: go all out.

  • Hold your race pace up to 4.4km, but stay in control.
  • Control your HR on the first mountain, and go all out on the final descent from 4.4km.
  • Start · 0.0km–2.1km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Work · 2.1km–4.4km · Plus 1 more climb. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 4.4km–8.7km · Descent of 254m averaging 6%, high point 2330m. Kick for the line: give it everything you've got. Long descent: keep it even and let go only near the end.

Course

The course climbs 280m+. With 28m/km of climbing, this is a rolling, mostly runnable course. By gradient, 25% of the distance is uphill, 40% downhill and 34% flat. The longest climb runs 4.4km at an average 6.8% grade (296m of vertical). The longest descent runs 4.3km at an average 5.9% grade (254m of vertical). The steepest climb averages 25.8% over 0.4km. The steepest descent drops at 11.6% over 0.6km. Surface: 71% trail, 17% road, and 12% smooth. Flat-equivalent effort: 11.7 FlatKM.

Poles

The course is runnable enough that trekking poles are not needed.

Quad damage

There is too little runnable descent to damage the quads: plan the race around climbing and fuelling.

  • Control your HR on the first mountain, and go all out on the final descent from 4.4km.

Weather

On race day, start temperatures have historically ranged from 7°C to 20°C, with around 14°C at the highest point; the chance of precipitation is about 6%.
