Short race: go all out.

The longest climb runs 2.5km at an average 12.5% grade (316m of vertical). The longest descent runs 5.1km at an average 7.1% grade (362m of vertical). The steepest climb averages 21.6% over 0.5km. The steepest descent drops at 37.5% over 0.4km. Surface: 73% trail, 14% road, and 14% smooth. Flat-equivalent effort: 13.9 FlatKM.
Poles bring little benefit here: only about 0.8km of pole-friendly terrain.
There is too little runnable descent to damage the quads: plan the race around climbing and fuelling.
