Midway between Baltimore and Philadelphia, this race is staged out of beautiful Perryville Community Park in Perryville, Maryland which is truly a hidden gem, a diamond in the rough. Nestled on forested bluffs overlooking the top of the Chesapeake Bay this park makes for the epicenter of a great race. The swim takes place in the Chesapeake Bay and features an in water start off the dock. The Sprint bike course is a rolling out and back course while the Olympic bike course is technical with a mix of suburbia, rolling farm country and a fast, flat drag strip along River Road.
