Race strategy
Hold a steady pace and save energy for every section.
- 528m 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 106km, then run your race pace.
- Start · 0.0km–1.6km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
- Settle in · 1.6km–12.1km · Climb of 505m, descent of 528m averaging 8%. 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 · 12.1km–81.1km · Climb of 558m, descent of 484m averaging 9%, descent of 321m averaging 12%. Plus 2 more climbs. 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 · 81.1km–146km · Descent of 679m averaging 5%, climb of 624m, climb of 501m. Plus 1 more climb and 3 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. 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 · 146km–157km · 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.
