Two answers here:

Firstly for the BC champ event, we can only offer those allowed by BC.  There are only two categories, Senior, and Veteran.  Veteran are defined as 40+.

For all other events, we will have the following categories:

• Senior – 18 – 29^th year
• Master – 30^th to 39^th year
• Veteran – 40^th to 49^th year
• Grand veteran – 50^th to 59^th year
• Super Grand veteran – 60+
• Single speed

(Obviously if there are only a few competitors in a cat, we may throw you in with the youngsters or the elders!)
