Estimated finish times
The route is about 137 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.

|---|---|
| 10 mph | 13h 40m |
| 12 mph | 11h 24m |
| 14 mph | 9h 46m |

| 18 mph | 7h 36m |
Most recreational riders average 12–16 mph on rolling terrain in a group, and less on hilly routes.
