The Thames Challenge Cup was instituted in 1868 for crews below the standard of the 'Grand' or the 'Ladies''. The event now has a number of exclusions to ensure that the 'Thames' is an event for typical club crews.
This was one of the three new eights events for women introduced in 2021. Like the 'Thames', the 'Wargrave' has a number of exclusions to ensure this is an event for typical club crews.
In the early days of the Regatta it was the custom for the challengers in each event to row trial heats among themselves, with the successful challenger contesting the final against the winners of the previous year. From 1847 The Wyfold Challenge Cup was presented to the winning challenger for The Grand Challenge Cup.
When this practice ceased in 1855, the trophy was made over to a new four-oared race for crews below the standard of The Stewards' Challenge Cup. The event now has a number of exclusions to ensure that the 'Wyfold' is an event for typical club crews.
This event was introduced in 1969 for lower-standard coxed fours, with a trophy presented by Nottingham Britannia Rowing Club to mark its centenary. It was originally open only to crews from the United Kingdom and the Republic of Ireland, but opened to overseas entries in 1988.
In 2004 a new student fours event, The Prince Albert Challenge Cup, was created. As a result, the 'Britannia' is now for club crews only, with similar restrictions to the other club events.
