Ride the Stelvio indoors: real climbs in 3D on your smart trainer

· 5 min read

Indoor riding is better when the road is real. Every climb in Domestique Hub's trainer is baked from the actual elevation of a real pass, and your smart trainer feels each gradient as you reach it.

Real passes, real gradients

The library includes the Passo dello Stelvio and the great Dolomite roads — the Giau, the Fedaia, the Pordoi, the Sella, the Gardena, the Falzarego and Valparola, the Mendola, the Jaufenpass and the Timmelsjoch — with more beyond Italy. Filter them by length, total ascent or steepness, or search by name or country.

Each ride is out and back. At the top you turn round, and the descent is the climb you have just done in reverse, at its real gradient.

The gradient goes to the trainer

In simulation mode the road's own grade at your position is streamed to the trainer as you ride into it, smoothed so it is not fighting you every metre. On a structured session the target watts take over instead, because two things cannot set the resistance at once — and you can now write those sessions yourself.

On iPad the climb is split into sections, each with its length, gradient and gain — and an estimate of how long it will take you.

The climb, section by section

Long climbs are hard to pace from a single number. So every course is split into sections — hairpins, steep ramps, the easier stretches between them — each with its length, average gradient and metres gained. The current section is highlighted, the panel shows the distance and the metres left to the top, and as you finish each section it records your time, average speed and power for it.

The club on the same road

Anyone riding the same road is on it with you, each rider on their own bike in their own kit, and the group column shows their power and heart rate exactly as it does outdoors. A solo turbo session becomes a club one.

No trainer? Try it anyway

Without a trainer paired, a ride runs as a demo with simulated power, clearly labelled as such and never saved as a real activity — so you can see the roads before you buy a trainer. And on a treadmill the same screen runs with the rider on her feet rather than on a bike.
