Noting you are in Sheffield, the nearest event is SCeetles and then Scouse Showdown in Liverpool
I'm offended, Lucy! Forgetting about us up in York

We host both Beetleweight and Featherweight events up at Robodojo on alternating months, 20 mins-ish drive outside of York station. We're a club rather than a dedicated event, so our events are chilled out and beginner friendly. You'd get chance to discuss, get help from and generally learn from our other members as well as practice.

Regardless, whichever event you go to, everyone is willing to help!
