Great River Race 2026: London's 21-Mile River Marathon Returns from Millwall to Richmond
London’s greatest water carnival returns to the River Thames as the Great River Race 2026 sets sail for an unforgettable test of endurance, camaraderie, and maritime pageantry. Often dubbed London’s River Marathon, this spectacular 21-mile rowing contest challenges hundreds of traditional rowing craft and over 2,500 rowers, coxswains, and passengers to navigate the tidal waters from the Isle of Dogs all the way up to Richmond.
Whether you are pulling an oar in a classic Cornish pilot gig or cheering from one of London's historic bridges with a pint in hand, the Great River Race offers one of the most vibrant free spectator events in the capital's sporting calendar.

The Route: 21 Miles Through the Capital
Tracing the tidal curves of the Thames, the race offers competitors and spectators an unparalleled journey through the heart of Greater London.
- Starting Point: Millwall Riverside (Isle of Dogs, E14). The fleet launches in staggered intervals according to a carefully calculated handicap system, allowing slower craft to head off first and creating a thrilling, bunched finish.
- The Central London Stretch: Boats glide beneath London's most iconic spans, including Tower Bridge, London Bridge, and Westminster Bridge, framed by the Houses of Parliament and the London Eye.
- The Upriver Meander: As the race pushes past Putney and Hammersmith, the urban scenery gives way to leafy riverbanks, passing Chiswick, Kew, and Twickenham.
- The Finish Line: Below Richmond Bridge, culminating near Ham Riverside, where exhausted crews are greeted by roars of applause, brass bands, and well-earned festival refreshments.

The Fleet: Tradition, Colour, and Competition
To preserve the historic character of river transport on the Thames, the race strictly limits entries to traditional human-powered craft propelled by at least four oars or paddles. You can expect to see:
- Cornish Pilot Gigs: Sleek, fast wooden boats built to historic 19th-century specifications.
- Watermen’s Cutters: Historic ceremonial rowing craft crewed by Thames livery companies.
- Dragon Boats & Hawaiian War Canoes: Highly decorated vessels bringing international river traditions to the Thames.
- Whalers, Skerries, and Celtic Longboats: Rugged sea-going rowing boats manned by spirited coastal crews from across the British Isles and Europe.
- Fancy Dress Crews: Alongside elite rowers pushing for record times, dozens of crews tackle the 21-mile haul in full theatrical costume, raising substantial sums for charity.
