The TERRA Club Championship comprises approx 10 rounds per year (weather permitting) and each round is made up of 3 X 10(minimum) lap races at the Hidden Valley Motorsport Raceway.
TERRA grades all racers into A, B and C grade for the Club Championship.
A racers grade is not dependent on the type or capacity of the bike they ride. TERRA grading is determined by the rider lap time. This has led to great racing as it is common to see 400cc bikes racing side by side with 600cc and at times 1000cc machines.
