Ride it in stages
Few riders hold 57 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.
6 stages of about 9.6 km — none over 50 minutes at 165 W.

Elevation profile

There are steeper climbs and there are higher roads, but very few places on earth let you start with your wheels next to the ocean and ride uphill, without a single real descent, to three thousand metres. The road leaves the surf town of Pāʻia, passes through Makawao’s ranch country and then winds up the flank of the volcano in long, even switchbacks.
The gradient is never brutal. What wears you down is the length: hour after hour of the same demand, through cane fields, eucalyptus, cloud and finally the bare cinder of the summit, inside Haleakalā National Park.
Why ride this route indoors?
- It may be the longest continuous paved climb you can ride — an endurance effort with no freewheeling at all.
- The moderate gradient lets you hold an aerobic zone for hours, which almost no real road allows.
- Indoors you skip the altitude, the cold summit and the flight to Maui, and keep the climbing.
Good to know
+Is this the official route of Haleakalā Sea to Summit?
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 Haleakalā Sea to Summit 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 Haleakalā Sea to Summit in stages?
Yes. Few riders want more than 50 minutes on a trainer in one go, so Cycloscape offers its 57 km in 6 stages of about 10 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.
