NDH Hamsterley Enduro is on 15th Feb, laid back event but it does use some of the descend bike park tracks, so it depends on what sort of riding do you do?
I did my first race there last year, expected red grade stages but was a bit surprised to see we were on the DH stuff for 2 of the 3 stages.
It was wet and once 300 riders practise all morning it was quite churned up. Good fun though, even though I hadn’t really had much practise on that sort of stuff!
