There are a few...not sure how close any of them are going to be, as they are a bit sparse...the South West is a bit lacking...but improving!
Look up the Tiverton club (Grass & Astro), check the South West region section on here, as there is a club in Cornwall too...in Hayle (fully grass) I think, but not sure what's it's called...plus there are a few other little indoor clubs I think...hopefully people will post about them shortly.
And if you feeling a bit adventurous...as most racers in the South West need to be...there is always WORM in Weston-super-Mare (Somerset)...newly built...so new that we've only just laid the first track onto our new Astro surface last night, and will be confirmed race dates very soon...latest track pic & vid
***HERE***
And our website is
www.worm-racing.co.uk
Pretty sure we're the only fully AstroTurf track in the region
Also near Weston there's the new Yatton indoor club...they have a BIG space that they are starting work on now to turn into a permanent outdoor sized indoor track...should be ace once it's done!!! They have a smaller track setup in an upstairs area currently.
Hope it helps!
