Stamford Run Club 5k/10k/Half Marathon

Stamford Run Club 5k/10k/Half Marathon is held in Stamford, Connecticut, on April 18, 2027, at Mill River Park. All three distances — the half marathon (13.1 miles), the 10K (6.2 miles) and the 5K (3.1 miles) — start together at 7:00 AM, on professionally timed courses with dedicated support along the way and a lively atmosphere from fellow runners and spectators.

Entries are capped at 1,000 runners in total, which keeps the start line manageable and the course uncrowded — useful if you are chasing a time. The race village is stocked with activations from major sponsors, exclusive giveaways and what you need before and after the finish. For an early start like this, get up at least two hours ahead and keep the pre-race meal small and familiar.
