What's It Take to Keep Up on the Group Ride?

A rider that weighs more than most went on a group ride over terrain with rolling to short, steep hills. The first plot shows the power riding with the group. It is characterized by short, intense efforts. The second plot shows the rider after leaving the group, riding alone. Notice the difference. In both segments of the ride, the average speed and average power are about the same.

Examining a typical effort from the group portion of the ride suggests the training efforts needed for improvement.
