SoNo Half Marathon & 5K

Saturday, October 20, 2018 • Norwalk, CT • Course Map

One of the newest events in the southwestern Connecticut half marathon scene, Norwalk’s SoNo Half Marathon & 5K marks its 4th annual running in 2018, just as the weather starts to turn cooler and the scenery more beautiful.

The half marathon course begins at Veteran’s Park in Norwalk. From there, runners head west along Washington Street before running past the South Norwalk train station and heading south on Dr. Martin Luther King Jr Drive. Runners continue south until this road ends and turn right at the fork onto Wilson Avenue. This portion of the course takes runners along residential tree-lined neighborhoods while continuing north along Highland Avenue.

Runners turn right onto Soundview Avenue near mile 4.5 and continue east along Soundview Avenue and Flax Hill Road before turning right onto Washington Street briefly and heading north. This section of the course marks the beginning of the half marathon’s second half, and the course leads runners past the Maritime Aquarium at Norwalk and through Oyster Shell Park and Mathews Park before crossing the river and heading south along East Avenue.

After passing the East Norwalk train station, runners keep going south toward Taylor Farm Park, running through Shady Beach Park and taking in the beach views before heading toward the finish line at Veteran’s Park. With a post-race party beginning 30 minutes after the half marathon’s start, the party is sure to be in full swing when many of the half marathoners cross the finish line.

Race organizers note that the time limit for the half marathon is 3 hours, 15 minutes, making the race primarily a runner’s race.
