About the race

Diamond in the Rough Triathlon is staged from Perryville Community Park in Perryville, Maryland, located on forested bluffs overlooking the Chesapeake Bay. The event offers both Olympic and Sprint triathlon and aquabike options.

  • Olympic: 1.5K swim, 26.8 mile bike, 10K run
  • Sprint: 750 m swim, 8 mile bike, 5K run

Swim courses start single file from the park dock into the Chesapeake Bay. The Olympic swim is a two-loop rectangular course with four yellow turn buoys and orange sighting buoys approximately every 75 meters. The Sprint swim follows the same rectangular perimeter for one loop. Organizers expect July water temperatures in the low to mid 80s and will post an official reading the Thursday before the race.

The Olympic bike course is technical and passes through town, suburbia and rolling farm country before a roughly five mile fast section along River Road. The Sprint bike is a rolling out and back route on low-traffic country roads. Run courses are out and back routes that run along the Chesapeake Bay with limited shade; aid stations with ice water and Gatorade are placed about every mile and mobile support is available.

All athletes must remain inside the park until the bike course is clear or park outside at the nearby fire department lot. The event is USA Triathlon sanctioned and includes multiple scoring categories. Visit the organization's website for the most recent information.
