The BDO Kalamunda 100 provides one of Perth’s most challenging rides through the picturesque hills of Kalamunda, Pickering Brook and Mundaring. It is specifically designed to put your legs to the test and check your fitness before the epic Dams Challenge in March. Register as an individual, with your riding partner or in a team. The event is fully supported and includes water stations along the course, motorbike marshals, first aid, broom wagon and more.

“A Distance” encompasses two loops of the circuit totalling 100km and in excess of 1,900 metres of climbing. “B Distance” is a single loop of the route and takes in 50km of riding with over 950 metres of climbing.

The event is a personal challenge and NOT a race – no place-getter prizes are awarded.
