In order to equalize the efforts in order to not burn some riders off too early, the weaker riders take shorter pulls and stronger riders take longer pulls, all at the same speed to minimize the change in pace. A rider finishing a pull usually rotates to the very back of the formation, and the rider who was formerly behind this rider takes over. A rider who needs more time to recover may take a longer time at the back of the formation while the other teammates rotate in front of this rider.
