← All eventsGrand Raid BCVS
~125km Alpine MTB marathon, Verbier → Grimentz, Valais, crossing three valleys. ~5,000m climbing — one of the biggest single-day loads in XCM, closer to an ultra. High passes, technical descents, hike-a-bike. Shorter starts + intermediate cutoffs. ~2,500 riders. Next edition ~21 Aug 2027 (approximate).
One of the biggest single-day climbing loads in mountain-bike marathon racing. This point-to-point Alpine crossing is closer to an ultra than a typical XCM.
Verbier to Grimentz, linking three Valais valleys over high passes above 2,000m. Rocky technical descents between them, with short hike-a-bike on the roughest ground.
Most riders are out for 8 to 13 hours. Intermediate cutoffs stop anyone off the pace, and the final climb into Grimentz punishes whoever went too hard early.
Is Grand Raid BCVS for you?
- Strong climbers with high power-to-weight. With this much ascent, every watt per kilo counts and every spare kilo is amplified.
- Big-engine endurance riders who can climb for hours without collapsing. This rewards all-day durability over one-hour sharpness.
- Confident technical descenders. The rocky Alpine descents make time, or cost it, and they come when your legs are already cooked.
- Self-sufficient riders comfortable being remote. The cols are exposed, and you carry your own food, fluid and spares between feed zones.
Training plan for Grand Raid BCVS
A training plan for Grand Raid BCVS isn't a generic base build. Beina reads the event's exact demands, looks at your specific profile and the time you actually have, and maps a highly adapted plan to the start line.
- 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.
- 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.
- Built from your current fitness and the time you actually have
- Adapts every week as Beina learns how you respond
- Syncs your sessions straight to Garmin and Wahoo
- One clear next session, never a wall of spreadsheet
