Orienteering Australia’s events, results and membership portal
Each class can be restricted by age ranges. There should be no minimum age on M/W21 ie a 17 yr old should be able to run/ride in that class.
If you are setting up an event you can edit the min/max ages for each class.
How do I ensure a 'youth' gets visability of higher age classes that he may want to 'ride-up' in e.g M21 i.e. does his year of birth restrict visability of classes to only those ones he eligible for?
