Italian Alps, Italy · from Prato allo Stelvio
Passo dello Stelvio by bike
The Stelvio from Prato is one of the longest and highest paved climbs in Europe, famous for its wall of 48 numbered hairpins stacked up the mountainside. The gradient grinds steadily upward for over two hours of climbing for most riders, with altitude becoming a real factor above 2,000 metres.
Summit elevation: 2758 m

FAQ
How long is the Passo dello Stelvio climb?
From Prato allo Stelvio, the climb is about 24.3 km with roughly 1787 m of elevation gain at 7.4% average gradient (based on the simplified profile used by this simulator; published figures vary slightly by source).
How long does it take to cycle up Passo dello Stelvio?
It depends almost entirely on your power-to-weight ratio. Use the simulator on this page: enter your FTP and weight, and a physics model (air resistance, rolling resistance, gravity) estimates your time on the gradient profile.
How accurate is the time simulation?
The simulator uses a simplified segment profile and standard road bike assumptions (CdA 0.32, Crr 0.004, 8 kg bike). It does not model wind, drafting, altitude, surface or pacing errors, so treat the result as a realistic estimate, not a guarantee.
How should I train for Passo dello Stelvio?
Sustained climbs reward steady threshold and sweet spot work plus a power-to-weight improvement over weeks, not days. TrainCraft builds structured cycling training plans and adapts them when you miss sessions, using fatigue science (CTL/ATL/TSB).
