About Serra de Tramuntana

Serra de Tramuntana is the 138km ultra trail at Mallorca by UTMB 2025 (Pollenca, Spain). The race starts on October 31, 2025.

Race strategy

Hold a steady pace and save energy for every section.

  • Steep 33% wall. Control your pace and stay focused.
  • 515m descent. Go easy, save your quads.
  • The finish is runnable. Save your legs to run it all the way.
  • Long race. Control your HR and effort. Early mistakes cost the most.
  • Control your HR on the first climb, save your quads on the descents until 120km, then run your race pace.
  • Start · 0.0km–1.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.3km–17.4km · 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 · 17.4km–70.1km · Descent of 417m averaging 9%, descent of 272m averaging 12%, descent of 515m averaging 11%. Plus 3 more climbs. This is where the race is built: steady, solid effort. 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. Running pays off here: run wherever you can. Hike the steepest pitches.
  • Fade · 70.1km–128km · Descent of 466m averaging 9%, climb of 651m, descent of 1484m averaging 8%, high point 1212m. Plus 1 more climb and 2 descents. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. 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. Running pays off here: run wherever you can. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 128km–136km · 8.4km 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.

Course

By gradient, 38% of the distance is uphill, 37% downhill and 25% flat. The longest climb runs 7.7km at an average 5.7% grade (444m of vertical). The longest descent runs 19.5km at an average 7.6% grade (1484m of vertical). The steepest climb averages 35.0% over 0.2km. The steepest descent drops at 32.9% over 0.5km. Surface: 53% trail, 20% road, 14% smooth, and 11% technical. Flat-equivalent effort: 187.6 FlatKM.

Poles

Poles bring little benefit here: only about 16.6km of pole-friendly terrain.

Quad damage

Quad damage risk is high (index 59 of 100), with 41% of the load in the first half: 5 critical descents, the last of them run on already damaged legs. Downhill-specific preparation and a controlled early pace pay off here.

  • Control your HR on the first climb, save your quads on the descents until 120km, then run your race pace.
  • #2 · 20.4–25.2 km · 417 m D−, -8.6% · 111.2 km ahead → control
  • #5 · 46.5–48.7 km · 272 m D−, -12.5% · 87.7 km ahead → control
  • #1 · 54.3–59.2 km · 515 m D−, -10.6% · 77.2 km ahead → control
  • #3 · 70.1–75.6 km · 466 m D−, -8.5% · 60.8 km ahead → control
  • #4 · 100.4–119.9 km · 1484 m D−, -7.6% · 16.5 km ahead → control
  • 125.1–128.0 km · 282 m D−, -9.6% · 8.4 km ahead → your pace
  • Plus 1 more notable descent not listed: your pace.
