The Summer Eights 2026

About the Summer Eights

Oxford’s iconic bumps regatta

The Summer Eights is one of two bumping boat races in Oxford’s rowing calendar, alongside the Torpids. The regatta takes place each May over four successive days, from Wednesday to Saturday of the fifth week of Trinity Term, drawing spectators and rowing enthusiasts from across the city and beyond.

Racing on the Isis

The races are held on the Isis, a stretch of the River Thames in Oxford. The river is generally too narrow for side-by-side racing, so crews compete in the traditional ‘Bumps’ format. In this style of racing, boats chase each other in single file, aiming to catch and ‘bump’ the crew ahead to move up the rankings.

For each division, twelve boats line up at the downstream end near Donnington Bridge, with each cox holding onto a rope attached to the bank, leaving roughly 1.5 lengths between boats. Racing begins with a series of cannon signals: a five-minute gun, a one-minute gun, and the starting gun.

When a bump occurs, both crews involved stop racing and move aside to allow the rest of the division to pass. The ultimate aim is to become Head of the River and retain the top position. It is also possible to over-bump, where a boat overtakes the one ahead if the two crews in front have already bumped, swapping places for the following day or next year.

Spectator experience

Expect the banks of the Isis to be packed with spectators, enjoying the excitement as oars slice through the serene waters. The atmosphere combines tradition, competition, and community, making Summer Eights one of Oxford’s most cherished sporting events.

The regatta is organised by Oxford University Rowing Clubs, the confederation overseeing all college crews and inter-collegiate contests within the University of Oxford. This includes the Oxford University Boat Club (OUBC), Oxford University Women’s Boat Club (OUWBC), the Oxford University Lightweight Rowing Club (OULRC), and the Oxford University Women’s Lightweight Rowing Club (OUWLRC).
