Grainau Trail

Race strategy

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

• Start easy and control your HR up to 7.6km.
• Final 742m descent. Save your legs to go all out on it.
• Control your HR on the first mountain, and start the final descent from 7.6km under control, then go all out near the bottom.
• 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–7.6km · Climb of 727m, high point 1441m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace.
• Home · 7.6km–15.7km · Descent of 742m averaging 9%. Build to the finish: leave whatever you have left out on the course. Very long descent: first half under control, then even, let go only near the end.

• 7.6–15.6 km · 742 m D−, -9.2% · 0.0 km ahead → even, first half under control, let go at the end
