About Chedi 20

Chedi 20 is the 17.0km trail race at HOKA Chiang Mai Thailand by UTMB 2025 (Chiang Mai, Thailand). The race starts on November 29, 2025.

Race strategy

Run hard on the first mountain, but save energy for the second.

  • Steep 26% wall. Control your pace and stay focused.
  • The finish is runnable. Save your legs to run it all the way.
  • Control your HR on the first mountain, then run your race pace.
  • Start · 0.0km–1.4km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.4km–7.5km · Descent of 225m averaging 16%, high point 612m. Plus 2 more climbs. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Hike the steepest pitches.
  • Work · 7.5km–9.0km · Plus 1 more descent. This is where the race is built: steady, solid effort. Hike the steepest pitches.
  • Home · 9.0km–16.4km · 7.4km of runnable trail. Build to the finish: leave whatever you have left out on the course. Running pays off here: run wherever you can.

Course

By gradient, 23% of the distance is uphill, 18% downhill and 59% flat. The longest climb runs 5.0km at an average 5.8% grade (291m of vertical). The longest descent runs 1.4km at an average 17.5% grade (250m of vertical). The steepest climb averages 35.2% over 0.2km. The steepest descent drops at 26.4% over 0.9km. Surface: 39% road, 35% trail, and 26% smooth. Flat-equivalent effort: 26.5 FlatKM.

Poles

Poles bring little benefit here: only about 2.2km of pole-friendly terrain.

Quad damage

Quad damage risk is low (index 9 of 100): a few descents worth noting, none of them decisive.

On race day, start temperatures have historically ranged from 19°C to 25°C, with around 23°C at the highest point; the chance of precipitation is about 13%.
