A block is an attempt in bicycle racing that is used to slow down or block the riders behind. The rider will take the lead position and ease up slightly for an individual attempting an escape. The teams employ such tactics.
Blocking is cooperation according to the rules. The riders can slow down, ride in front of their teammates, or create tiny openings for their teammate to lead. Blocking requires situational awareness, communication, and quality bike handling. Blocking is ideal in stage racing or crit racing, where tactical planning can alter the outcome. Blocking is not like draft errors since blocking is not about pushing someone away, but regarding intelligent blocking and racing technique.
