Tightest radius per curve

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

Curve character

Of 123.1 km, 48.8 km run through curves. The rest is straight or a junction turn.

Tight: 1.7 km, 1.4 %; radius under 60 m
Medium: 19.7 km, 16.1 %; 60 to 180 m
Wide: 27.4 km, 22.5 %; 180 to 400 m
Straights and junctions: 73.4 km, 60.1 %

Key figures of the route

How it was measured

Route: a round trip from Thun, 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 Thun?

There are three lengths: 60, 120, 200 km. The calculated routes measure 62.0, 123.1, 202.9 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 Thun have?

On 120 km we count 277 curves, 235 of them away from junctions. That is 191.0 free curves per 100 km.

How tight is the tightest curve?

On 120 km the tightest radius is 17 m, at km 36.0. The median radius of all curves is 80 m.

How much climbing does the route have?

On 120 km it is 1937 m of ascent. The highest point is 1752 m, the lowest 537 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.
