About HK20

HK20 is the 20.5km trail race at Hochkönig Ultraks 2026 (Maria Alm, Austria). The race starts on June 6, 2026.

Race strategy

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

  • 351m descent. Go easy, save your quads.
  • Final 530m descent. Save your legs to go all out on it.
  • Control your HR on the first mountain, save your quads on the way down from it until 7.2km, then run your race pace, and start the final descent from 14.7km under control, then go all out near the bottom.
  • Start · 0.0km–1.7km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.7km–7.2km · Descent of 351m averaging 9%. 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.
  • Work · 7.2km–14.7km · Climb of 488m, high point 1283m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 14.7km–20.4km · Descent of 530m averaging 9%. Build to the finish: leave whatever you have left out on the course. Very long descent: first half under control, then even, let go only near the end.

Course

The course climbs 1020m+. With 50m/km of climbing, this is a true mountain course with sustained climbs and descents. By gradient, 40% of the distance is uphill, 44% downhill and 15% flat. The longest climb runs 7.5km at an average 6.5% grade (488m of vertical). The longest descent runs 5.8km at an average 9.2% grade (530m of vertical). The steepest climb averages 21.4% over 1.1km. The steepest descent drops at 19.0% over 0.6km. Surface: 60% trail, 26% smooth, 7% technical, and 7% road. Flat-equivalent effort: 27.9 FlatKM.

Summits

The highest summit on the course is Natrun (1253m), 3.3km from the start.

Poles

Poles bring little benefit here: only about 3.9km of pole-friendly terrain.

Quad damage

Quad damage risk is low (index 16 of 100): a few descents worth noting, none of them decisive.

  • Control your HR on the first mountain, save your quads on the way down from it until 7.2km, then run your race pace, and start the final descent from 14.7km under control, then go all out near the bottom.
  • #1 · 3.1–7.2 km · 351 m D−, -8.6% · 13.2 km ahead → control
  • 14.7–20.4 km · 530 m D−, -9.2% · 0.0 km ahead → even, first half under control, let go at the end
