Race strategy

Hold a steady pace and save energy for every section.

• 471m descent. Go easy, save your quads.
• 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 53.6km, 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–13.4km · Climb of 855m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace.
• Work · 13.4km–53.6km · Descent of 471m averaging 8%, descent of 364m averaging 7%, descent of 420m averaging 5%. 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 · 53.6km–85.2km · Climb of 679m, high point 2361m. 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. 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 · 85.2km–91.4km · Climb of 631m. No heroics: settle back into your own effort and hold it to the line. Climb by heart rate or breathing, not pace.

Course

The course climbs 4700m+. With 51m/km of climbing, this is a true mountain course with sustained climbs and descents. By gradient, 43% of the distance is uphill, 35% downhill and 23% flat. The longest climb runs 13.4km at an average 6.4% grade (855m of vertical). The longest descent runs 9.7km at an average 7.9% grade (762m of vertical). The steepest climb averages 32.9% over 0.3km. The steepest descent drops at 26.4% over 0.2km. Surface: 47% smooth and 15% trail. Flat-equivalent effort: 136.9 FlatKM.

Poles

Poles bring little benefit here: only about 16.0km of pole-friendly terrain.

Quad damage

Quad damage risk is moderate (index 45 of 100), with 40% of the load in the first half: 3 descents deserve a plan and a couple of downhill sessions before race day.

• Control your HR on the first mountain, save your quads on the descents until 53.6km, then run your race pace.
