Not to be confused with the Great Race between Oxford and Cambridge rowing crews, this traditional boat race sees a great flotilla of over 300 oar-powered craft take to the Thames for a river marathon race from London Docklands to Richmond. Any bridge upstream from the Docklands will afford a good view of the competing boats with the fleet expected to reach Tower Bridge 30 minutes after starting, Waterloo Bridge after an hour and finishing at Richmond after about two to three hours. Most of the craft will proceed upstream at a leisurely pace, so there will be hours between the leaders and the stragglers. For a list of the best viewing spots check the official site but Tower Bridge will probably be busiest, with Battersea Bridge and promenades giving great views. This is just part of a huge programme of events this month from the Totally Thames Festival. Check out our guide for more details.
