The competition rules are based on the IUF Rulebook 2019 with some adjustments.

Competitions will be held in the following categories:

Open for male, trans and non-binary riders (and as an optional choice for female riders)
Female for riders assigned female at birth

each category will have the following sub categories:

Junior consisting of the age groups
'Kids' (0-9 years)
'Junior' (10-14 years)

Adult consisting of the age groups
'Adult' (15-34 years)
'Senior' (35-49 years)
'Master' (50+ years)

Flatland will be held according to similar rules to those we tested at Winter EUC 2025, meaning with shorter prelim runs and no Last Trick, but significantly more battles. However, we want to use the experiences from Winter EUC to further optimize the rules. The final version of the rules used at the GUC will be available here soon.
