About SKY 15K Promesas

SKY 15K Promesas is the 15.5km trail race at HOKA Val d'Aran by UTMB 2025 (Vielha, Spain). The race starts on July 5, 2025.

Race strategy

Short race: go all out.

  • Hold your race pace up to Cap de Blanhiblar, but stay in control.
  • Control your HR on the first mountain, then run your race pace, and go all out on the final descent from 12.6km.
  • Start · 0.0km–2.6km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Work · 2.6km–12.6km · Climb of 637m, high point 2402m. Plus 1 more climb and 1 descent. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 12.6km–15.4km · Descent of 377m averaging 14%. Kick for the line: give it everything you've got.

Course

The course climbs 790m+. With 51m/km of climbing, this is a true mountain course with sustained climbs and descents. By gradient, 39% of the distance is uphill, 50% downhill and 11% flat. The longest climb runs 8.7km at an average 7.3% grade (637m of vertical). The longest descent runs 3.4km at an average 9.6% grade (323m of vertical). The steepest climb averages 24.6% over 0.4km. The steepest descent drops at 29.1% over 0.2km. Surface: 45% trail and 37% smooth. Flat-equivalent effort: 22.7 FlatKM.

Poles

Quad damage

Quad damage risk is low (index 10 of 100): a few descents worth noting, none of them decisive.
