About riding in Pennsylvania
Pennsylvania is hilly nearly everywhere, from the Appalachian ridges through central valleys to rolling farmland in the south-east. Even routes that look moderate on a map can involve steady climbing. Late spring through fall is the riding season.
Estimated finish times
The route is about 900 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 | 90h 00m |
| 12 mph | 75h 00m |
| 14 mph | 64h 17m |
| 16 mph | 56h 15m |
| 18 mph | 50h 00m |
Most recreational riders average 12–16 mph on rolling terrain in a group, and less on hilly routes.
