Event Overview

The Diamond in the Rough Triathlon Festival takes place in Perryville Community Park, Maryland, situated on forested bluffs overlooking the Chesapeake Bay. Located midway between Baltimore and Philadelphia, the event utilizes the park as a central hub for multiple multisport disciplines. Participants swim in the Chesapeake Bay, cycle through the rolling farm country of Cecil County, and run along the waterfront.

Race Distances and Formats

The festival offers several competition formats across two primary distances:

  • Olympic Triathlon: Includes a 1.5 km swim, a 26.8 mile bike ride, and a 10 km run.
  • Olympic Aquabike: Consists of a 1.5 km swim and a 26.8 mile bike ride.
  • Sprint Triathlon: Features a 750 meter swim, an 8 mile bike ride, and a 5 km run.
  • Sprint Aquabike: Comprises a 750 meter swim and an 8 mile bike ride.

Relay team options are also available for these distances.

Course Details

The swim starts from a park dock with a single-file, jumping entry into the Chesapeake Bay. The rectangular course is marked with buoys, and water temperatures in July typically range between 80 and 85 degrees Fahrenheit.

The bike courses vary by distance. The Sprint course is a rolling out-and-back route on country roads. The Olympic course is more technical, featuring rolling terrain through cropland and forests, followed by a flat section along the Susquehanna River on River Road.

The run course consists of out-and-back loops through Perryville Community Park and the Perry Point VA Medical Center grounds. The path is mostly flat, follows sidewalks and back roads, and offers views of the confluence of the Chesapeake Bay and the Susquehanna River. Aid stations providing water and electrolyte drinks are located at every mile. Visit the organization's website for the most recent information.
