12 Mile Creek Trail Half Marathon & 7k
The half marathon (21 km) race follows a historic route which includes the first Welland Canal and the 12 Mile Creek Trail. The first leg of the race includes the Merritt Trail towards downtown St.Catharines, then heads back to the trails behind Brock University, but only after you have confronted the beastial Hydro Hill and then descend the Niagara escarpment to the finish. The half marathon field is limited to 175 runners and has sold out for the last two years.
The 7 km race, for those that would prefer a shorter distance, is a challenging trail section which incorporates the last part of the half marathon. The field is limited to 100 runners and sold out quickly last year.
The half marathon walker division (21km) uses the same route as the running division and starts 90 minutes earlier.

In October 2019, a simple question sparked something real in St. Catharines: why not here? The Corners Run Crew emerged from that belief, built on two principles that define everything they do: Moderate Pace and Positive Space. Around 40 runners now show up week after week to sweat, laugh, and connect. Founded on the conviction that everyone belongs regardless of ability or background, The Corners Run Crew meets three times weekly, Tuesday and Thursday evenings plus Saturday morning trails. No attitudes, only love. That is the Corners way, a community where you show up, lace up, and find your people.
