E101 Ultra Trail

Race strategy

Hold a steady pace and save energy for every section.

• Steep 41% wall. Control your pace and stay focused.
• 1496m descent. Go easy, save your quads.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Control your HR on the first mountain, save your quads on the descents until 36.9km, then run your race pace, and go all out on the final descent from 62.9km.
• Start · 0.0km–1.8km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.8km–13.9km · Climb of 1204m. 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.
• Work · 13.9km–36.9km · Descent of 597m averaging 12%, climb of 891m, high point 2392m, descent of 1496m averaging 16%. 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.
• Fade · 36.9km–62.9km · Climb of 1296m. Plus 1 more climb and 1 descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 62.9km–67.1km · Descent of 404m averaging 10%. 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.

Poles

Trekking poles are worth taking: about 12.5km of the course favours them.

Quad damage

Quad damage risk is high (index 52 of 100), with 52% of the load in the first half: 2 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 mountain, save your quads on the descents until 36.9km, then run your race pace, and go all out on the final descent from 62.9km.
• #2 · 13.9–18.8 km · 597 m D−, -12.2% · 48.3 km ahead → control
• #1 · 27.7–36.8 km · 1496 m D−, -16.4% · 30.2 km ahead → control
• 44.7–62.0 km · 1583 m D−, -9.2% · 5.1 km ahead → your pace
• 62.9–67.1 km · 404 m D−, -9.6% · 0.0 km ahead → even, let go at the end
