About Half Marathon 21K

Half Marathon 21K is the 21.0km trail race at Everest Marathon 2027 (Namche Bazaar, Nepal). The race starts on May 29, 2027.

Race strategy

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

  • 718m descent. Go easy, save your quads.
  • High point at 4334m. Control your HR at altitude.
  • Steep 34% wall. Control your pace and stay focused.
  • Go easy on the first downhill, save your quads on the descents until 9.5km, 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–10.7km · Descent of 718m averaging 8%, high point 4334m. 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. This descent is hard on the legs: short steps, stay in control, poles if you have them. At altitude your pace drops, and that's fine.
  • Work · 10.7km–13.1km · Plus 1 more descent. This is where the race is built: steady, solid effort. At altitude your pace drops, and that's fine. Hike the steepest pitches.
  • Home · 13.1km–19.5km · Climb of 372m. Build to the finish: leave whatever you have left out on the course. Climb by heart rate or breathing, not pace. At altitude your pace drops, and that's fine.

Course

By gradient, 25% of the distance is uphill, 65% downhill and 10% flat. The longest climb runs 6.4km at an average 5.8% grade (372m of vertical). The longest descent runs 9.5km at an average 7.5% grade (718m of vertical). The steepest climb averages 37.8% over 0.3km. The steepest descent drops at 34.0% over 0.8km.

Poles

Poles bring little benefit here: only about 1.4km of pole-friendly terrain.

Quad damage

Quad damage risk is moderate (index 20 of 100), with 56% of the load in the first half: 1 descent deserves a plan and a couple of downhill sessions before race day.

  • Go easy on the first downhill, save your quads on the descents until 9.5km, then run your race pace.
  • #1 · 0.0–9.5 km · 718 m D−, -7.5% · 10.0 km ahead → control
  • 10.7–13.1 km · 565 m D−, -24.0% · 6.4 km ahead → your pace
