Tightest radius per curve

56 curves sit at junctions and are left out of these figures, for example turns with a small radius.

Curve character

Of 65.2 km, 22.3 km run through curves. The rest is straight or a junction turn.

Tight: 1.7 km, 2.7 %; radius under 60 m
Medium: 10.3 km, 16.4 %; 60 to 180 m
Wide: 10.2 km, 16.2 %; 180 to 400 m
Straights and junctions: 40.8 km, 64.6 %

How it was measured

Route: a round trip from Chamonix, calculated on road data from 3 Jul 2026. Of several possible loops of the same length we show the one with the most rideable curves. Motorways are excluded.
Vehicle: The route is calculated for a motorcycle and runs on paved roads. A car can drive it too. On narrow stretches a car route can differ in detail.
Curve: a turn in one direction of at least 35 degrees. The DriveBattle app counts the same way.
Radius: the tightest curve radius inside the curve. Turns at junctions are flagged and do not count towards radius, tightest curve or passage.
Elevation: ground height along the route, smoothed over about 450 m. A climb counts from a 5 m height difference.
Calculated on 5 Oct 2026. The figures describe this route. The state of the road on the day you ride can differ.
