Intervals.icu

What the mountain throws at you

Typical sessions

A mass start on snow off a 3,330m glacier: nerve and a clean line off the front

Around 2,600m of continuous descent that tests grip and arm-pump, not FTP

Snow, shingle, rock and alpine singletrack at speed, all high-consequence

Qualification heats that seed your start group, a genuine performance lever

What your weeks look like

Typical sessions

Long descent laps on shuttle or lift runs to build arm-pump resistance over a long descent

Consequential terrain days on loose, steep and snow or scree ground where you can access it

Short punchy repeats, 8 to 10 x 30 to 90 seconds hard, for the pedally lower trails and qualifying

Mass-start practice: a committed sprint start into technical terrain to rehearse the chaos
