A 26 hour tennis marathon will be played by coaches at the Wilton Tennis Club in Wimbledon for Sport Relief.
Wilton club coaches Jack Hankey and Darius Adomonis will play a non-stop doubles match for 26 hours and 385 seconds, the equivalent time to the amount of miles of a marathon run.
It will start on Saturday, March 29, at 3pm and end at 6.30pm on Sunday, March 30.
Get involved by becoming an umpire or a ball person or playing against the pair by donating to Sport Relief on the website.
There are lots of activities planned for the weekend event at the club in Wilton Grove, Wimbledon.
