Welcome to the CORCscrew Enduro


Our Friends at CORC (Collingwood Off Road Cycling) are ready to put on an enduro that will showcase the awsome community in this region and the equally awesome trail network at the Highlands Nordic/Duntroon trail system. Springboarding off the past success of two enduros that have been run at this event thus far, they are looking to continue the party and add some new trails.

The trail netowrk is just 15 minutes south of Collingwood and runs along the Niagara Escaprment. Expect some healthy enduro segment lengths on singletrack that boasts a nice balance of flow and technical elements.
