What do I need to know?
Ridium's training read and the caveats before you trust the times.
Training read · Ridium AIThe Triple is an extreme high-altitude alpine road route of roughly 194 km with about 3,682 m of climbing, spending its entire length above 2,260 m and topping out near 3,657 m. The day is shaped by two huge category-HC passes early on plus two shorter category-3 climbs later, with gradients reaching about 18%.
- Altitude
The whole route sits above roughly 2,260 m and climbs to about 3,657 m, so if you live near sea level, plan how you will manage thin air; arriving several days early to acclimatize, when feasible, may help your effort feel more controlled.
- Climbing
Two early category-HC passes dominate the day: a roughly 23.6 km climb with about 1,043 m of gain to near 3,398 m, then a roughly 28 km climb with about 1,106 m of gain over Loveland Pass to about 3,653 m. With about 24 weeks of preparation available, building sustained tempo and threshold climbing of 60 to 90 minutes can prepare you for these long efforts.
- Endurance
With about 194 km, roughly 3,682 m of climbing, and an estimated finish time of up to about 14.5 hours, this is rated an extreme endurance route; long back-to-back rides on hilly terrain over many weeks can build the durability needed to keep moving all day.
- Pacing
Gradients touch about 18% and two later category-3 climbs near Frisco and Vail Pass arrive deep in the route, so holding back on the early HC passes and pacing to the finish venue cutoff at 8:00 PM can help you avoid blowing up in the final third.
- Fueling
A ride of this length and climbing load burns through stored energy, so practising a steady eating and drinking routine on your long training rides, and rehearsing it at the pace you expect on event day, can help keep your energy stable across the passes.
- Technical
Mountain descending is a key demand between the passes, with long alpine downhills on closed roads; practising relaxed braking and cornering on long descents beforehand can make the high-speed sections feel more controlled, especially when you are tired.
