The Great River Race is a spectacular boat race covering 21.6 miles from Millwall in the East to Richmond in the West. Almost 300 boats take part, from dedicated athletes who come every year to beat their records to those who simply enjoy laughter, fancy dress and making money for their charity. It’s a great fun day out for both competitors and spectators. Watch from anywhere along the course, or come to Ham riverside for food, bar and a disco.
Catch the race from London’s iconic bridges. For the full schedule please visit The Great River Race.
