From the Organizer

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. The run course is mostly flat and winds its way along the Chesapeake Bay on sidewalks and back roads. This event is not to be missed and Cecil County is a great area to explore. Sailing, hiking, dining and more can be found minutes from the race site, you can learn more HERE.

****All athletes must stay in the park until the bike route is clear of incoming bikes.  If you must leave prior to the bike course being clear you MUST park outside the park at the fire department lot, approximately 1.35 mile from the race site.  If you park inside the park, all cars will be “locked in” until the police deem the roads safe to allow cars to exit.  Our goal is a safe race for ALL athletes and we appreciate your cooperation in this matter.
