Just wanted to throw out this reminder for Cat 5 riders.
Each coaching session at the Early Birds counts as 1 races of experience towards your Cat 4 upgrade. Each race also counts as a race of experience. This means if a Cat 5 does the coaching session and the race they get 2 races worth of credit towards the Cat 4 upgrade. A new Cat 5 that attends all 5 weeks and does the coaching and racing each week will qualify for an upgrade to Cat 4 at the end of the Early Bird series.
