Ultra-Trail des Paiens

Race strategy

Hold a steady pace and save energy for every section.

• 484m 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.
• Control your HR on the first mountain, save your quads on the descents until 77.6km, then run your race pace.
• 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–15.7km · Climb of 543m, descent of 484m averaging 7%. Ease in: hold back more than feels necessary. The race is still ahead. 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.
• Work · 15.7km–59.3km · Descent of 322m averaging 12%, climb of 643m, descent of 893m averaging 5%. Plus 1 more climb. 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 · 59.3km–98.1km · Climb of 622m, high point 817m, descent of 710m averaging 7%, climb of 501m. Plus 1 more climb and 2 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. This descent is hard on the legs: short steps, stay in control, poles if you have them. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 98.1km–109km · 11.3km 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.
