The course

The route

125km from the Verbier start to the finish climb at Grimentz (around 1,570m), with roughly 5,000m of ascent. That works out at about 40 vertical metres per kilometre, relentlessly up and down at altitude.

Training for the Grand Raid BCVS

Beina integrates directly with your existing tools to understand your current fitness, and synchronise your planned sessions.

Intervals.icu

A relentless Alpine climbing day

Typical sessions

Sustained Alpine climbs, one after another, that reward power-to-weight above all else.

Racing at altitude, where thin air saps your sustained power if you arrive unacclimatised.

Rocky, steep technical descents between valleys, ridden on increasingly tired legs.

Fast-changing mountain weather: cold exposed cols, hot valleys, possible rain or even summer snow.

What your weeks look like

Typical sessions

Long climb intervals: 3x15-20min at 88-95% FTP on a real climb, for sustained climbing power.

Big climbing days building toward 3,500m-plus of ascent, the key event-specific session.

Back-to-back mountain weekends: a big climbing day Saturday, then a 4-5hr ride Sunday, for cumulative fatigue.

Technical descents ridden at the end of a long climb, so you handle rocky ground fatigued.
