A head race is a type of rowing competition where boats race against the clock rather than directly against each other. Typically held on a river or lake, these races are often longer in distance, usually ranging from 2,000 to 5,000 meters. Each crew starts at staggered intervals, allowing them to focus on their own performance without interference from other boats. Head races are popular in the rowing community, especially during the fall season. They provide an opportunity for teams to test their speed and endurance in a time-trial format. Events like the Head of the Charles and the Head of the Schuylkill are well-known examples of head races, attracting crews from various levels and regions.
