Red Course

Race strategy

Run hard on the first mountain, but save energy for the second.

• Big early climb with 1.1km gain. Hold your pace, save your legs for later.
• 523m descent. Go easy, save your quads.
• Final 910m descent. Save your legs to go all out on it.
• 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 23.7km, then run your race pace, and start the final descent from 51.8km under control, then go all out near the bottom.
• 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–17.1km · Climb of 1098m, high point 1107m. 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 · 17.1km–30.1km · Descent of 523m averaging 8%. This is where the race is built: steady, solid effort. 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 · 30.1km–51.8km · 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. 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 · 51.8km–58.7km · Descent of 910m averaging 13%. No heroics: settle back into your own effort and hold it to the line. Very long descent: first half under control, then even, let go only near the end.

Quad damage

Quad damage risk is moderate (index 34 of 100), with 28% of the load in the first half: 1 descent deserves a plan and a couple of downhill sessions before race day.

• Control your HR on the first climb, save your quads on the descents until 23.7km, then run your race pace, and start the final descent from 51.8km under control, then go all out near the bottom.
• #1 · 17.1–23.7 km · 523 m D−, -7.9% · 35.0 km ahead → control
• 30.1–32.5 km · 251 m D−, -10.5% · 26.2 km ahead → your pace
• 51.8–58.7 km · 910 m D−, -13.3% · 0.0 km ahead → even, first half under control, let go at the end
