O'Hartford 5K and 10K
The O'Hartford 5K and 10K takes place in Hartford, Connecticut on March 15, 2026. The event is presented by Trinity Health Of New England Orthopedics and uses a course that runs through the Coltsville Historic District, with both races finishing at midfield inside Trinity Health Stadium.
The event offers multiple distance options:
- 5K
- 10K
A walker friendly 5K and an HMF FitKids event are included; the FitKids races are 1/4 mile or 1/2 mile for children ages 2 to 11. All participants receive a custom St. Paddy's inspired short sleeve technical shirt. After the race, participants age 21 and over with ID are eligible for an ice cold beer and all participants may enjoy post race food.
The O'Hartford weekend connects with HMF seasonal challenges. The Lucky Challenge spans four O' races with virtual and in-person combination options. The Li'l Lucky option recognizes completion of any two of the four St. Paddy's themed races and awards a finisher medal to Li'l Lucky participants.
The Hartford Marathon Foundation operates the event as a non-profit. The race supports local giving through the HMF Can food collection near packet pickup and lists the HMF Susie Beris, MD Youth Running Program as the event charity beneficiary.
