The Three Rivers Race is an annual event, held usually on the first Saturday of June. It covers the three rivers of the northern Broads - Bure, Ant and Thurne - the idea being, to visit specified points on each of the rivers and return to Horning as quickly as possible. For the very fast craft, this is a race of 8-9 hours, but there is always a trickle of yachts returning to Horning throughout Sunday!

This year, Horning Sailing Club will be celebrating the 50th Anniversary of the Three Rivers Race, with 172 boats taking part.

Norfolk Brass will be performing a concert on Swan Green beside the Swan Inn prior to the race, which starts at 11:00am.
