Check with Farside on this – but any licensed racer may participate in the clinic. I took my 5yr old last year and I was 38 then and not the oldest participant.
Greg’s clinics are good for all ages. If you are a rookie, novice, expert, or even a pro you will definitely benefit from a Greg Hill clinic. There are only a couple of spots still available. You can pm or email me to add your name to the list.
