Race strategy
Hold a steady pace and save energy for every section.
- 494m descent. Go easy, save your quads.
- High point at 3029m. Control your HR at altitude.
- 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.
- Go easy on the first downhill, save your quads on the descents until 126km, 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–32.8km · Descent of 494m averaging 4%, climb of 823m. 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 · 32.8km–80.5km · Plus 1 more climb. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
- Fade · 80.5km–143km · Climb of 840m, descent of 960m averaging 6%, high point 3029m. 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. 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. At altitude your pace drops, and that's fine. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
- Home · 143km–156km · 12.3km 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.
