About riding in the United Kingdom
Britain's cycling is defined by rolling country lanes, short steep climbs and changeable weather. Conditions can shift quickly, so rain gear and layers are sensible even in summer. Sportives are popular from spring through early autumn.
Estimated finish times
The route is about 107 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 | 10h 42m |
| 12 mph | 8h 55m |
| 14 mph | 7h 39m |
| 16 mph | 6h 41m |
| 18 mph | 5h 57m |
Most recreational riders average 12–16 mph on rolling terrain in a group, and less on hilly routes.
