The race, which began in 1925, is the only true remaining handicap event in WA. It is steeped in tradition and is the premier road race on the Western Australian cycling calendar.
The handicap format gives everyone a chance to get to the finish line first.
It also includes the 2021 Under 15 and Under 17 Australian Cycling WA Junior Road State Championships.
The historic race begins in the WA coal mining town of Collie, 200km south of Perth, and heads through hilly terrain towards Mumballup for 21km before turning and heading towards the township of Donnybrook. This is the halfway point. Riders then turn and return back to Mumballup. The last 21km of the course is very arduous through the hills to the finish line in the main street of Collie. The riders will complete 104 kilometers in total.
