Not to be confused with the Great Race between Oxford and Cambridge rowing crews. This traditional boat race sees a great flotilla of oar powered craft take to the Thames for a semi-competitive 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, Westminster Bridge 15 minutes later and getting to Richmond around 2pm. Most of the craft will proceed upstream at a leisurely pace, so there may be hours between the leaders and the stragglers. For a list of the best viewing spots, check the official site.
