Ride it in stages
Few riders hold 10 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.
2 stages of about 5.1 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.

Sa Calobra is a dead end: the road was built in the 1930s to reach a cove, and the only way out is back up. It climbs from the water through a narrow cleft in the rock, then uncoils across the mountainside in more than twenty hairpins, with the sea behind you almost the whole way.
Near the top is the bend everybody knows — the ‘tie knot’, where the road loops a full circle and passes under itself. It is a steady, honest gradient from bottom to top, which is why it has become the benchmark climb of every spring training camp on the island.
Why ride this route indoors?
- On the island you have to descend it before you can climb it. Indoors you start at the sea.
- A steady gradient for well under an hour makes it an ideal repeatable test: the same effort, the same road, a number you can beat.
- It is the climb half the professional peloton uses to check its form in winter — a fair yardstick for yours.
Good to know
+Is this the official route of Sa Calobra?
No. It was recreated by Cycloscape from open map data (OpenStreetMap) following public descriptions of the route, for indoor training. It may differ from the official route or from current road conditions.
+What do I need to ride Sa Calobra indoors?
A smart trainer or a power meter, and a browser. Cycloscape connects over Bluetooth or ANT+ from the browser, sets the resistance of a smart trainer to the real gradient, and turns the route’s GPX into a 3D world. There is nothing to install.
+Can I ride Sa Calobra in stages?
Yes. Few riders want more than 50 minutes on a trainer in one go, so Cycloscape offers its 10 km in 2 stages of about 5 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.
+Is it free?
Yes. Riding it needs a free account — sign up in seconds with Google or a code by email, no card. Your result is saved and goes on the route’s leaderboard.
