Measured on the route line from OpenStreetMap data, which can be missing or out of date. Curvature is degrees of turning a mile, measured every 100 metres. On our routes they run from 6 on the E19 to 701 on the SP638.

Before you go

• The high cols (Iseran, Galibier, Cayolle) are normally open from June to October only. Check before you go.
• This follows the official line over the Col de la Cayolle. Many riders swap in the Col de la Bonette, between Jausiers and Saint-Etienne-de-Tinee, which is higher still.
• Cyclists in large numbers on every col in summer.
• Fuel up in the valley towns. There is none on the passes.

Split it into days

Pick the miles you like to ride in a day. Each day ends at the named place on the route nearest that distance, and you get a GPX file for each day.

This is your pace, not our estimate of how long the riding takes. Day lengths vary because each day ends at a named place.
