About Mist 20K

Mist 20K is the 26.0km trail race at Amazean Jungle Trail by UTMB 2026 (Betong, Indonesia). The race starts on April 30, 2026.

Race strategy

Run easy on the first mountain, then go all out on the second.

  • Start easy and control your HR up to 13.4km.
  • Hold your race pace up to 16.7km, but stay in control.
  • 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–1.0km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.0km–13.4km · Climb of 366m, high point 702m. Plus 1 more climb and 1 descent. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace.
  • Work · 13.4km–16.7km · Plus 1 more descent. This is where the race is built: steady, solid effort.
  • Home · 16.7km–22.7km · 6.0km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.

Course

Poles

Poles bring little benefit here: only about 1.5km of pole-friendly terrain.

Quad damage

Quad damage risk is low (index 12 of 100): a few descents worth noting, none of them decisive.

  • 13.4–16.7 km · 318 m D−, -9.7% · 6.0 km ahead → your pace
