The course

The route

The full route stacks a few long Alpine ascents for 3,600m of climbing over 88km, high point above 2,000m, linked by technical exposed singletrack descents through Grindelwald's high alps. Shorter 55km and 30km options run the same terrain.

What the Eiger throws at you

Typical sessions

3,600m of climbing over a few long, sustained ascents: the day is won on the climbs.

Technical, rocky, exposed high-mountain singletrack descents, ridden on deep-fatigue legs.

Racing above 2,000m, where you lose a few percent of power and descents turn genuinely cold.

A 5 to 9 hour day for most riders, with fast-changing Alpine weather and long gaps between feeds.

What your weeks look like

Typical sessions

Tempo and threshold climb repeats: 3 to 4 x 15min on a long climb for sustainable climbing power.

Big climbing days: 4 to 6 hour rides banking 2,000 to 3,500m of ascent.

Descend-under-fatigue: technical descents saved for the end of a long ride, mirroring the race.

Sweet spot on gradient: 2 to 3 x 15min at 88 to 94% FTP to lift your threshold without frying you.
