Race strategy

Short race: go all out.

• Hold your race pace up to 4.8km, but stay in control.
• Control your HR on the first mountain, and go all out on the final descent from 4.8km.
• Start · 0.0km–1.9km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Work · 1.9km–4.8km · Climb of 472m, high point 1439m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
• Home · 4.8km–9.5km · Descent of 470m averaging 10%. Kick for the line: give it everything you've got. Long descent: keep it even and let go only near the end.

Course

The course climbs 500m+. With 50m/km of climbing, this is a true mountain course with sustained climbs and descents. By gradient, 38% of the distance is uphill, 50% downhill and 12% flat. The longest climb runs 4.8km at an average 9.9% grade (472m of vertical). The longest descent runs 4.7km at an average 9.9% grade (470m of vertical). The steepest climb averages 26.2% over 0.4km. The steepest descent drops at 36.9% over 0.3km. Surface: 68% trail, 18% road, and 12% technical. Flat-equivalent effort: 12.3 FlatKM.

Poles

Poles bring little benefit here: only about 1.4km of pole-friendly terrain.

Quad damage

There is too little runnable descent to damage the quads: plan the race around climbing and fuelling.

• Control your HR on the first mountain, and go all out on the final descent from 4.8km.
• 4.8–9.5 km · 470 m D−, -9.9% · 0.0 km ahead → even, let go at the end
