Course

The event is held at Perryville Community Park in Perryville, Maryland, on forested bluffs overlooking the top of the Chesapeake Bay. The swim takes place in the Chesapeake Bay and starts in the water from a dock.

The Sprint bike course is described as a rolling out-and-back route. The Olympic bike course is technical, featuring a mix of suburbia, rolling farm country, and a fast, flat section along River Road. The run course is mostly flat and winds along the Chesapeake Bay on sidewalks and back roads.

Registration & Information

Registration includes a finisher medal, a long-sleeved tech shirt, custom race socks, a reusable bag for packet pickup, timed results, age group awards, a post-race meal, a finisher certificate, and free finish line photos. The event uses a time-trial swim start, with athletes starting two at a time, and offers an Elite Box Start for those aiming for top overall positions.

A notable rule is that all athletes must remain in the park until the bike route is clear of incoming bikes for safety. Vehicles parked inside the park will be unable to leave until police deem the roads safe. Visit the organization's website for the most recent information.
