UPDATE: Dan Church will be on Paternity leave for 2 weeks and Emily L will cover these sessions so no one misses out. Thanks for your understanding. A great way for players aged 10-18yrs to progress from Mini Green tennis: slightly larger rackets, soft balls and full-sized courts. Enables players to develop a rounded game, learning a range of techniques and tactics. These sessions are still primarily games based but now with a focus of the kids taking more ownership of their learning.
