How it was measured

Route: a round trip from Písek, 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.

How much climbing does the route have?

On 120 km it is 931 m of ascent. The highest point is 591 m, the lowest 369 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.
