Course Outline:

The ride starts off with a very pleasant ride from the Luke Harrop Circuit at Runaway Bay down past the beautiful beaches from Surfers Paradise through to Miami before heading inland to Mudgeeraba. It’s at this point that the tempo picks up as the riders head north through Highland Park, Mount Nathan and Pimpana where it is 30 kms of gruelling hills – one after another – until riders get to the 80 km mark where it returns to a more even level once again right through to the finish line back at the Luke Harrop Circuit, Runaway Bay.

There are two Rating 5 climbs on the event. The first is around the 38 km mark with a length of 2.81 km and an average grade of 3%. The second is at the 44 km mark  with a length of 2.40 km and an average grade of 2.7%.
