How it was measured

Route: a round trip from Niort, 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.

Questions about the round trip

How long is the round trip from Niort?

There are three lengths: 60, 120, 200 km. The calculated routes measure 55.7, 124.9, 186.3 km.

Can I drive the round trip by car?

Yes. The route runs over paved country roads without motorways and can be driven by car and motorcycle. It is calculated for a motorcycle, so on very narrow stretches a car route can differ in detail.

How many curves does the round trip from Niort have?

On 120 km we count 134 curves, 77 of them away from junctions. That is 61.7 free curves per 100 km.

How tight is the tightest curve?

On 120 km the tightest radius is 29 m, at km 104.1. The median radius of all curves is 69 m.

How much climbing does the route have?

On 120 km it is 755 m of ascent. The highest point is 211 m, the lowest 21 m.

Can I ride this round trip with the app?

Yes. The round-trip generator in the DriveBattle app calculates loops from your location with the same method.

The round-trip generator is part of Premium. During the beta it is open to everyone.
