Estimated finish times
The route is about 104 miles per riding day (2 days, ~207 miles total). 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.

|---|---|
| 10 mph | 10h 21m |
| 12 mph | 8h 38m |
| 14 mph | 7h 24m |
| 16 mph | 6h 28m |
| 18 mph | 5h 45m |
Most recreational riders average 12–16 mph on rolling terrain in a group, and less on hilly routes.
