Everyone on here will recommend you race off-road, much more fun and there are loads of tracks in the Nottinghamshire/Derbyshire/Lincolnshire/Yorkshire area.
The YORCC club who run most of the events at RHR have an indoor venue in York.

Personally, I own the RHR track and am involved with running Worksop indoor racing.

I have been working on building an indoor dirt track at the RHR venue for a long time, who knows when it could be, maybe next year
