Rule update day! Thanks for the input throughout the 2025 season from event organisers, our wider crew and the community. No massive changes this year but still worth reading the changelogs to see if they will affect you.
Do check with your organiser before competing whether they have any modifiers and if they’re aware of the updates, we try and keep a list of current UK ruleset modifiers at the bottom of each page linked below.
