About MUZ30

MUZ30 is the 30.9km skymarathon at Mayrhofen Ultraks Zillertal 2025 (Mayrhofen, Austria). The race starts on September 6, 2025.

Race strategy

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

  • Final 1705m descent. Save your legs to go all out on it.
  • Steep 35% wall. Control your pace and stay focused.
  • Control your HR on the first mountain, and start the final descent from 15.2km under control, then go all out near the bottom.
  • 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–15.2km · Climb of 1620m, high point 2124m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Hike the steepest pitches.
  • Home · 15.2km–29.8km · Descent of 1705m averaging 12%. 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. Hike the steepest pitches.
