In a road bicycle race, the peloton is the main group or pack of riders. Riders in a group save energy by riding close to other riders. The reduction in drag is dramatic; riding in the middle of a well-developed group, drag can be reduced to as little as 5–10%. Exploitation of this potential energy saving leads to complex cooperative and competitive interactions between riders and teams in race tactics. The term is also used to refer to the community of professional cyclists in general.

Peloton riding in a straight line to increase slipstreaming, thus reducing drag and conserving energy for cyclists behind, often for key riders such as sprinters or GC cyclists
A sprinter is a road bicycle racer or track racer who can finish a race very explosively by accelerating quickly to a high speed, often using the slipstream of another cyclist or group of cyclists tactically to conserve energy.
