This is run by the Nottingham Tennis Centre (see links)
It runs during the winter months, we have several teams in the leagues.
It is a slightly strange fast and furious format!
Matches last for 90 minutes and involve teams of 4 players; 2 men and 2 ladies.
You play 45 minutes of straight doubles (upto 16 games) and then 45 minuites of mixed (upto 16 games). All games count towards the final score, so for example you can draw 32-32 or lose 64-0 it's never happened to us yet. Deuces are sudden death and the indoor courts are pretty fast.
There is one match each month from October through March on a Sunday or Monday evening duration from 19:00 to 20:30 or the late shift 20:30 to 22:00.
