Ultra maraton

Race strategy

Hold a steady pace and save energy for every section.

• 267m 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.
• Ease into the early runnable section, save your quads on the descents until 39.7km, then run your race pace.
• Start · 0.0km–1.6km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.6km–21.3km · 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 · 21.3km–57.5km · Descent of 267m averaging 7%. Plus 2 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.
• Fade · 57.5km–96.0km · Climb of 386m, high point 533m. Plus 2 more climbs and 3 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. Running pays off here: run wherever you can. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 96.0km–106km · 10.3km 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.

Quad damage

Quad damage risk is moderate (index 44 of 100), with 49% of the load in the first half: 1 descent deserves a plan and a couple of downhill sessions before race day.

• Ease into the early runnable section, save your quads on the descents until 39.7km, then run your race pace.
• #1 · 35.7–39.7 km · 267 m D−, -6.8% · 66.7 km ahead → control
• 68.7–72.8 km · 283 m D−, -6.9% · 33.5 km ahead → your pace
• 75.7–83.0 km · 396 m D−, -5.4% · 23.3 km ahead → your pace
• 89.9–93.4 km · 347 m D−, -9.9% · 12.9 km ahead → your pace
