The Head of the River Race is one of the London's longest running sporting traditions.

Every spring, 400 crews from around the globe take to the waters of London's famous river Thames to compete in this historic boating event.

The race was started in 1926 by Cambridge and Tideway oarsman Steve Fairbairn. It was conceived as a way for crews to practice long rows during winter, in preparation for the summer regatta.

The annual event now sees hundreds of boats, each manned by eight men, row over the 4.25 mile (6.8km) championship course from Mortlake to Putney. The race sees crews from all over the world competing, from Australia to Austria.

It is customary for the previous year's winner to start first. They are followed at 10-second intervals by other crews in finishing order and finally, the new entries start in alphabetical order.

The event is a great way for Londoners and visitors alike to celebrate the start of spring as they cheer on teams along London's picturesque river Thames.

Don't forget to pack your Pimm's and arrive early to grab a good viewing spot!

Where to Watch the Head of the River Race

The banks of the river Thames are brimming with spectators for the race. See the crews off from Chiswick Bridge, cheer them on from Barnes Bridge as they gather pace, or see the crews approach from the busy Hammersmith Bridge – alternatively, you may be lucky enough to find a spot on the river banks along the course or a seat in a cosy pub. All of these locations can become very busy, so get there at least 45 minutes before the race to secure a good spot.
