The course

The route

A single mass start at roughly 3,400m on the glacier, then a mostly downhill dash of around 2,400m of vertical over 26km. Snow and ice at the top give way to bike-park tracks, singletrack, rock and fire road in the valley.

What the mountain throws at you
Typical sessions
A chaotic mass start on snow and ice at 3,400m, a thousand riders funnelling off the glacier together.
Roughly 2,400m of near-continuous descent on snow, shingle, rock and fast bike-park trail.
Non-stop braking that fatigues grip and forearms, with arm-pump a real risk on the lower trails.
Short pedally sections toward the valley where a burst of fitness protects your speed.
What your weeks look like
Typical sessions
Long technical descents, repeating runs of 1,500m or more until the hands fatigue, to build descending durability.
Loose-terrain skills: steep, off-camber and braking-control drills for snow and shingle-like ground.
Full bike-park days for gravity volume and confidence.
Punchy intervals, 6 to 10 by 30 to 60 seconds, plus start-scramble drills for a calm getaway off the line.
