E35 - North Face Trail

Race strategy

Hold a steady pace and save energy for every section.

• 326m descent. Go easy, save your quads.
• Steep 28% wall. Control your pace and stay focused.
• The finish is runnable. Save your legs to run it all the way.
• Control your HR on the first mountain, save your quads on the way down from it until 8.6km, then run your race pace.
• Start · 0.0km–1.5km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.5km–19.0km · Climb of 738m, descent of 326m averaging 13%, climb of 937m. 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. Running pays off here: run wherever you can. Hike the steepest pitches.
• Work · 19.0km–30.6km · Climb of 403m, high point 2339m, descent of 1382m averaging 15%. 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. Hike the steepest pitches.
• Home · 30.6km–35.6km · 5.1km 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.
