La Rock'Voizine

Race strategy

Hold a steady pace and save energy for every section.

• 257m descent. Go easy, save your quads.
• Final 580m descent. Save your legs to go all out on it.
• Go easy on the first downhill, save your quads on the descents until 4.1km, then run your race pace, and go all out on the final descent from 44.4km.
• 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–27.3km · Descent of 257m averaging 6%, high point 875m. 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. Running pays off here: run wherever you can.
• Work · 27.3km–33.1km · Plus 1 more climb and 1 descent. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
• Fade · 33.1km–44.4km · Plus 2 more climbs 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. 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 · 44.4km–49.9km · Descent of 580m averaging 11%. No heroics: settle back into your own effort and hold it to the line.
