Follow event Run/Walk Off Road/Trail Relay

The Collie River Ultra Marathon from 17 to 19 September 2027 features a 100km, 80km relay and 50km in the stunning Collie River Valley, WA.

The details on this page are based on the previous event and subject to change; we will update this listing as more information comes to hand.

The 100km course follows the wild and beautiful Wiilman Bilya Trail and takes runners over the top of one of the most iconic dam wall murals in the Southern Hemisphere. You’ll run over bridges, circumnavigate Wellington Dam, through magnificent Yarri, Marri and Jarrah forest on single trails in a massive loop of unique trail.

The 80km relay (teams of 2 - 5) starts at the same point but halfway through the final leg, the 100km runners split off onto a different trail to collect a few more kms, before rejoining the Final Relay Leg to continue with the rest of the runners to the rewarding finish.

Relay leg lengths vary from 12km to 20.5km.
