42 km Trail

Race strategy

Run the climb at race pace, build your speed on the downhill, and go all out at the finish.

• 311m descent. Go easy, save your quads.
• 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 8.0km, then run your race pace.
• Start · 0.0km–1.9km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.9km–8.0km · Descent of 311m averaging 8%. 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.
• Home · 8.0km–41.4km · 33.4km of runnable trail, high point 555m. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.
