Oshawa

Oshawa's running scene is flat and road-focused along the Lake Ontario waterfront; the Shoppers Drug Mart Run for Women in nearby Whitby and local 5K races draw steady participation on the low-rolling terrain. Cyclists dominate here—the Hell of the North 100km gravel epic and Trail Hub Bike Fest both launch from the region, taking riders into the oak ridges and backroad networks north and east toward the Kawartha Lakes, offering serious mixed-terrain distance racing within easy reach of the GTA.
