About mozart Marathon

mozart Marathon is the 45.0km trail race at mozart 100 by UTMB 2025 (Fuschl am See, Austria). The race starts on May 23, 2025.

Race strategy

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

  • Final 978m descent. Save your legs to go all out on it.
  • Steep 27% wall. Control your pace and stay focused.
  • Control your HR on the first climb, then run your race pace, and go all out on the final descent from 31.5km.
  • Start · 0.0km–1.9km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.9km–28.4km · 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 · 28.4km–31.5km · Plus 1 more climb. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 31.5km–44.2km · Descent of 978m averaging 8%, high point 1098m. No heroics: settle back into your own effort and hold it to the line. Long descent: keep it even and let go only near the end. Hike the steepest pitches.
