Ride it in stages
Few riders hold 25 km on a trainer. Ride it a stage at a time: the cuts avoid the middle of the big climbs — a stage ends at a summit, in a valley or on the flat — and this page remembers what you have ridden and what comes next.
4 stages of about 6.2 km — none over 50 minutes at 165 W.

Times are at a steady 165 W — no stage takes more than 50 minutes. Cross a stage's finish line and it is ticked — feeling good? Keep pedalling and the ride carries on into the next stage. Progress is kept in this browser, and in your account when you are signed in.
Elevation profile

The climb from Prato is the side in the photographs. It starts quietly along the Solda river through Gomagoi and Trafoi, and then the valley ends and the road has no choice but to go up the headwall: hairpin after hairpin, each with its number on a stone, counting down from forty-eight.
The road was engineered in the 1820s and has barely changed since. The last third is above the treeline, with the whole ladder of bends visible below you and the pass — and the thin air — above. When the Giro d’Italia comes here it is usually the highest point of the race.
Why ride this route indoors?
- The pass is closed by snow for most of the year; indoors it is open in January.
- Two hours of near-constant gradient is a rare training stimulus, and the numbered bends make the effort easy to break into pieces.
- The altitude that makes the real summit so hard is the one thing you can leave out while you build the legs for it.

+What do I need to ride Passo dello Stelvio — Prato indoors?

+Can I ride Passo dello Stelvio — Prato in stages?
Yes. Few riders want more than 50 minutes on a trainer in one go, so Cycloscape offers its 25 km in 4 stages of about 6 km, none longer than 50 minutes at 165 W. The cuts avoid the middle of the big climbs — a stage ends at a summit, in a valley or on the flat. Start from any stage and, if your legs are good at its finish line, keep pedalling: the ride carries on into the next stage and every stage you finish is ticked. The page remembers which stages you have ridden and which one is next.
