About Trail Tour

Race strategy

Run easy on the first mountain, then go all out on the second.

  • 268m descent. Go easy, save your quads.
  • Steep 30% wall. Control your pace and stay focused.
  • Control your HR on the first mountain, save your quads on the way down from it until 7.6km, then run your race pace, and go all out on the final descent from 35.1km.
  • Start · 0.0km–2.0km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.0km–16.9km · Descent of 268m averaging 9%, climb of 987m, high point 2091m. Plus 1 more climb. 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 · 16.9km–35.1km · Descent of 832m averaging 7%. This is where the race is built: steady, solid effort. 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.
  • Home · 35.1km–38.5km · Descent of 395m averaging 11%. No heroics: settle back into your own effort and hold it to the line. Hike the steepest pitches.
