How it was measured

  • Route: a round trip from Jena, 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.

Calculated on 5 Oct 2026

There are three lengths: 60, 120, 200 km. The calculated routes measure 67.0, 130.3, 206.3 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 Jena have?

On 120 km we count 232 curves, 175 of them away from junctions. That is 134.3 free curves per 100 km.

How tight is the tightest curve?

On 120 km the tightest radius is 19 m, at km 75.6. The median radius of all curves is 75 m.

How much climbing does the route have?

On 120 km it is 1347 m of ascent. The highest point is 531 m, the lowest 146 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.
