Odyssée 100K

Race strategy

Hold a steady pace and save energy for every section.

• Final 640m descent. Save your legs to go all out on it.
• Steep 26% wall. Control your pace and stay focused.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Ease into the early runnable section, then run your race pace, and go all out on the final descent from 71.9km.
• Start · 0.0km–1.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.3km–32.2km · Climb of 626m. 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 · 32.2km–42.4km · Plus 1 more descent. This is where the race is built: steady, solid effort. Running pays off here: run wherever you can.
• Fade · 42.4km–71.9km · Climb of 628m, high point 929m, climb of 553m, climb of 512m. Plus 2 more 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. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 71.9km–76.9km · Descent of 640m averaging 13%. 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. Hike the steepest pitches.
