To take the lead on a paceline or echelon.

This means riding on the front of a paceline or peloton. To “take a pull” means you’re the person working the hardest since you’re not getting any benefits from drafting. In a rotating paceline, take a short pull, drift to the side, and then roll to the back of the line and let the next person pull.

Draft until it’s your turn to be on the front again. This is a tactic used by groups for maximum efficiency on long rides or when there’s a strong headwind.
