About riding in Slovenia
Slovenia is a compact country with alpine climbs, quiet valley roads and a short stretch of Adriatic coast. Traffic is light on many routes, and late spring through early autumn is the best time to ride.
Estimated finish times
The route is about 83 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 | 8h 20m |
| 12 mph | 6h 56m |
| 14 mph | 5h 57m |
| 16 mph | 5h 12m |
| 18 mph | 4h 38m |
Most recreational riders average 12–16 mph on rolling terrain in a group, and less on hilly routes.
