These races are three rounds in already, so I'm a little late in sharing, but the final two rounds are coming up. Details here: https://my.raceresult.com/groups/5114/
It's an excellent race series on the north edge of Swindon that has been running for over ten years. Heartily recommended. After round 5 on 29th, there's a small presentation event in the on-site bar with frites and mayo for all.
I've been doing these races for years and am happy to help with any questions, although I unfortunately can't offer a lift. Other than a CX or gravel bike (no MTBs allowed), the only thing you need that is different is a decent front light as not all parts of the course are floodlit.
