Head to Portland on Mother's Day (Sunday, May 10th at 9:15 am) for this friendly 24th annual 5K hosted by the Portland Sea Dogs and Maine Track Club, featuring a complimentary Kids Run at 8:30 am. This flat, scenic route through the city starts at the Portland Expo and finishes at Fitzpatrick Stadium, with the first 750 runners receiving commemorative shirts and everyone taking home free Sea Dogs game tickets. Top finishers score trophies and prizes—including 2026 season tickets and a first pitch opportunity for the overall winners—while all race proceeds support the American Cancer Society's breast cancer programs.
