Bumps race

A bumps race is a form of rowing race in which a number of boats chase each other in single file, each crew attempting to catch and "bump" the boat in front without being caught by the boat behind.

The form is mainly used intramurally at the University of Cambridge, since 1827, and at the University of Oxford since 1815. Bumps racing in fours is also the format of intramural rowing at Eton College and at Shrewsbury School. It is particularly suitable where the stretch of water available is long but narrow, precluding side-by-side racing. Bumps racing gives a sharper feel of immediate competition than a head race, where boats are simply timed over a fixed course. Few rowers worldwide use rivers as narrow as the Cam or the Isis, but bumps races are also contested elsewhere (see below).

Racing practice and procedures

Bumps races are typically raced in a series over several days. The starting order of each day's race is based on the previous day's results; the first day's starting order each year is determined by the results on the last day of the previous year. Each day the boats line up bow-to-stern, usually along the bank of the river, with a set distance between each boat and the next (usually about one and a half boat-lengths of clear water). The starting positions are usually marked by a rope or chain attached to the bank, the other end of which is held by each boat's cox. Boats wait along the bank, and may be poled out just in time for the start, to avoid drifting. At the start signal the cox lets go of the rope and the crew starts to row, attempting to catch and bump the boat in front while simultaneously being chased by the one behind.
