What To Expect At Collie River MTB Marathon
70km Race Course
Some updates for the Collie MTB Marathon 70km race for 2025!
We're back out at Harris River Estate Winery for 2025! About 5km's north of Collie and at the heart of the Arklow MTB Trails Network. A fantastic place for the event village - with food vans and vendor displays.
For 2025 we've reverted back to a single loop from HRE winery and back with less road crossing points. You'll leave the winery and head across Harris River Road and straight onto the '220' trail heading North, then back down on the 'Far Lap' trail. From here you'll ride up 'Bull Ant' and then head out on a northern loop on some great old fire trail. Once back you'll continue down 'Bull Ant' and then along the Munda Biddi and up Arklow Road for a great little descent back down towards the Munda Biddi trail. From there you'll race along 'Pet Cemetry', across the creek crossing (yep! It's back for 2025!) and up the Munda Biddi and the top part of 'Jarrah Jaunt' before flying down Railway Rise. Towards the bottom of Railway Rise you'll take a hard right and join back onto the 'Arklow Adaptive' loop and head back to the HRE Winery using 'Mornington Glory' and 'Dead Cats' trails. Here you'll cross back over Harris River Road and do a quick lap of 'Rays Trail' before finishing in the winery grounds to the cheers of the adoring fans!
