The NWCCA series of races as pointed out by fishbulb are just about half way through with 6 of the 11 race series completed. A great series of races for all levels and ages and very well supported. Nice and friendly competition and family orientated. You can enter on the day and you pay a little extra for a British Cycling day licence if you aren't registered with them.Its a bit more expensive than most fell races, £14.00 plus a couple of quid for the day license.Give it a try, highly recommended
