About mozart Marathon

mozart Marathon is the 44.0km trail race at mozart 100 by UTMB 2026 (Fuschl am See, Austria). The race starts on May 23, 2026.

Race strategy

Run the climb at race pace, build your speed on the downhill, and go all out at the finish.

  • 500m descent. Go easy, save your quads.
  • Steep 27% wall. Control your pace and stay focused.
  • The finish is runnable. Save your legs to run it all the way.
  • Ease into the early runnable section, save your quads on the descents until 27.3km, then run your race pace.
  • Start · 0.0km–2.0km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.0km–20.4km · 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. Running pays off here: run wherever you can.
  • Work · 20.4km–27.3km · Descent of 500m averaging 7%, high point 1090m. This is where the race is built: steady, solid effort. This descent is hard on the legs: short steps, stay in control, poles if you have them. Hike the steepest pitches.
  • Home · 27.3km–43.6km · 16.3km 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.

The longest climb runs 4.0km at an average 9.7% grade (383m of vertical). The longest descent runs 6.9km at an average 7.2% grade (500m of vertical). The steepest climb averages 34.5% over 0.2km. The steepest descent drops at 31.1% over 0.2km. Surface: 53% trail, 37% road, and 6% smooth. Flat-equivalent effort: 51.6 FlatKM.

Summits

Poles

Poles bring little benefit here: only about 1.9km of pole-friendly terrain.

Quad damage

Quad damage risk is low (index 19 of 100): a few descents worth noting, none of them decisive.

  • Ease into the early runnable section, save your quads on the descents until 27.3km, then run your race pace.
  • #1 · 20.4–27.3 km · 500 m D−, -7.2% · 16.3 km ahead → control
