Race strategy

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

• Final 2438m descent. Save your legs to go all out on it.
• Steep 26% wall. Control your pace and stay focused.
• Ease into the early runnable section, then run your race pace, and start the final descent from 26.0km under control, then go all out near the bottom.
• 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–6.6km · Ease in: hold back more than feels necessary. The race is still ahead. Running pays off here: run wherever you can.
• Work · 6.6km–26.0km · Climb of 1517m, high point 2434m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
• Home · 26.0km–43.2km · Descent of 2438m averaging 14%. No heroics: settle back into your own effort and hold it to the line. Very long descent: first half under control, then even, let go only near the end. Hike the steepest pitches.

• Ease into the early runnable section, then run your race pace, and start the final descent from 26.0km under control, then go all out near the bottom.
• 26.0–43.2 km · 2438 m D−, -14.2% · 0.0 km ahead → even, first half under control, let go at the end
