Twelve Mile Creek Trail Half marathon

The Twelve Mile Creek Trail Half Marathon and 7k Cancer Run is an annual event held in St. Catharines, Ontario, supporting the Niagara Rankin Cancer Run. The 2025 edition marks the 36th occurrence of this race, featuring a challenging 21.1 km half marathon route that includes scenic trails and the ascent of Hydro Hill on the Niagara escarpment.

For those preferring a shorter distance, a 7 km run is also available, incorporating the latter part of the half marathon course. Participants can register for both running and walking divisions, with proceeds contributing to cancer support initiatives. Visit the organization's website for the most recent information.
