I’m thinking about doing a race or enduro but I’ve no idea which one to choose

There’s no way I could manage an endurance event, and I’ve only got one bike, a patriot, although I might be able to borrow a hardtail from my brother

Just looking for something that would be fun as a challenge to myself, not bothered about getting fast times, more something I could realistically complete

Brecon Beast is always a good day out.

CRC marathon series?

nmot races but events and certainly have the feeling of an event IME.

I enjoyed the Ruthin one even if all the whippets overtook me on the ups for me to overtake on the downs again, (well some of them anyway!)
