Join us for a race that’s bigger than the miles.

On Sunday, April 19, 2026, Stamford Run Club proudly welcomes runners of all levels to Mill River Park for the SRC 5K, 10K & Half Marathon—a high-energy celebration of running, community, and Stamford pride.

Whether you’re chasing a PR, running your first race, or soaking in the atmosphere with friends, this event is designed to deliver an unforgettable race-day experience in the heart of downtown Stamford.

Founded in 2024, Stamford Run Club has grown rapidly into one of the area’s most welcoming and consistent running communities. What started as weekly Wednesday night runs has become a movement—bringing together runners of all paces through shared miles, connection, and commitment.

In just two years, SRC has:

Built a thriving local running community
Hosted multiple successful community races
Created a race experience rooted in inclusivity, energy, and fun

This year’s event marks a major milestone with the return of a half marathon to Stamford for the first time in over 30 years, bringing long-distance road racing back to the heart of the city. Headlined by Kane Footwear and lululemon and supported by an incredible lineup of local sponsors and vendors, the race goes far beyond the start and finish line.

Runners can expect a vibrant race village at Mill River Park, premium sponsor activations and giveaways, professional timing and course support, and a community-first race-day energy that carries through to a post-race atmosphere that feels like a true celebration. To preserve the quality of the experience, registration is capped at 1,000 total runners across all distances, and early registration is strongly encouraged as this event is expected to fill.

PLEASE READ! - UPDATE TO COURSE ROUTES AND LAPS

Due to some recently imposed restrictions from the City of Stamford, we have had to make adjustments to the course route in order to comply with these restrictions.

5K and 10K Runners

5k Runners and 10k Runners will complete the course map below one time and two times respectively.

Half Marathon Runners

Instead of performing the route 4 times, the updated route now consists of 3 laps of the original course (starts in Mill River, heads up to Scalzi Park and then back down towards Mill River) and 6 laps within and around Mill River Park along the paths and sidewalks to complete the half marathon. (see second image)

With the new time constraints, you must complete the first 3 laps (approx 9.8, averaging about a 15 min. mile) within 2.5 hours. After that time, the closure of the roads included in the main course route will no longer be available. If you do not think you can complete the 3 laps within that time frame, we ask you sign-up for the 5k or 10k.
