Groovy Granite

Groovy Granite returns for its third edition at Lee River, on Treaty 1 territory, the ancestral lands of the Anishinaabe, Cree, Oji-Cree, Dakota, and Dene Peoples and the National Homeland of the Red River Métis.

The event uses the historic grounds of the AECL Underground Research Laboratory and follows the rim of a large granite batholith. Runners see the Lee River, stretches of Boreal Forest, and weathered rock formations. The course is looped and offered in multiple distances.
