In massed start bicycle races, riding in a group to avoid air resistance is profitable for racing cyclist to save their energy consumption. In this study, we estimated cyclists' power output and analyzed the relationship to the group size in a national championship of track cycling points race. The results show that the average velocity of the group increased as the number of riders in a group increased to some extent, but the average velocity of the large group decresed as the size of the group increased. These results suggest that the small groups are formed by cyclists intended to raise the pace and, on the other hand, the large groups are formed to save energy cunsumption by cyclists intended not to raise the pace.
