Diamond in the Rough Triathlon : Perryville Community Park

The event is staged at Perryville Community Park in Perryville, Maryland, on forested bluffs overlooking the northern reaches of the Chesapeake Bay. The swim takes place in the Chesapeake Bay with an in water start off the dock. The sprint bike course is a rolling out-and-back route. The Olympic bike course is described as technical and mixes suburban streets, rolling farm country, and a fast, flat stretch along River Road. The run is mostly flat and follows sidewalks and back roads along the Chesapeake Bay.
