Ultra Extreme Marathon

Race strategy

Hold a steady pace and save energy for every section.

• 290m 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 31.1km, then run your race pace.
• Start · 0.0km–1.4km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.4km–24.9km · 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 · 24.9km–76.9km · Descent of 290m averaging 5%. Plus 2 more climbs and 1 descent. 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 · 76.9km–119km · Descent of 327m averaging 8%, high point 531m. Plus 3 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 · 119km–132km · 13.3km 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.

Poles

Poles bring little benefit here: only about 15.9km of pole-friendly terrain.

Quad damage

Quad damage risk is high (index 53 of 100), with 54% of the load in the first half: 1 critical descent. Downhill-specific preparation and a controlled early pace pay off here.

• Ease into the early runnable section, save your quads on the descents until 31.1km, then run your race pace.
• #1 · 24.9–31.1 km · 290 m D−, -4.7% · 101.3 km ahead → control
• 55.0–58.7 km · 252 m D−, -6.8% · 73.7 km ahead → your pace
• 92.3–95.8 km · 252 m D−, -7.2% · 36.5 km ahead → your pace
• 112.4–116.5 km · 327 m D−, -8.1% · 15.9 km ahead → your pace
