I had no idea that there were any closed road rallies in England (or Wales or Scotland for that matter) - I'm sure I've read that the NI rallies are unique in the UK being on closed roads. But it turns out there is at least one, the Hills Ford Stages organised by Cheltenham Motor Club (which I'm not a member of - I think I'm a member of both Farnborough and Bath MCs but not the one close to where I live

)
https://hillsfordstages.co.uk/ is the link. I saw mention of it on the local news website. Here's Cheltenham MC's brief page:

Not sure if I've got time this weekend to get the bobble hat out and watch (bit last minute finding out about it), but it's good to know this exists.
