About riding in Germany
Germany offers well-marked cycling infrastructure, rolling hills and low mountain ranges such as the Black Forest, plus flatter northern plains. Weather is generally mild but changeable. Spring through early autumn is the main season.
Estimated finish times
The route is about 133 miles. Here is the moving time at a steady average speed. It is a flat-ground baseline: climbing, wind, stops at aid stations and group riding all move the real number, so treat it as a starting range.
| Average speed | Moving time |
|---|---|
| 10 mph | 13h 18m |
| 12 mph | 11h 05m |
| 14 mph | 9h 30m |
| 16 mph | 8h 19m |
| 18 mph | 7h 23m |
Most recreational riders average 12–16 mph on rolling terrain in a group, and less on hilly routes.
