Join this beloved Mother's Day Sunday tradition in Cambridge, MD, starting at Gerry Boyle Park by Great Marsh, where you can run a half marathon (13.1 miles) and/or a 5K (3.1 miles) that winds past the Choptank River and through Dorchester County's scenic country roads. The half marathon course mirrors the June Eagleman event, and if you're feeling ambitious, tackle the King Crab challenge by completing the half marathon in under 2 hours to earn a spot at the 5K start. Packet pickup opens Sunday morning from 6:30-7:15 AM (with additional 5K registration from 7:45-9:15 AM), the half marathon starts at 7:30 AM, the 5K begins at 9:30 AM, and awards wrap up at 10:30 AM.
