Diamond in the Rough Triathlon : Perryville, Maryland

The Diamond in the Rough festival stages Olympic and Sprint triathlons, plus relay and aquabike options, from Perryville Community Park on forested bluffs overlooking the Chesapeake Bay. The swim takes place in the Chesapeake Bay with a single-file, in-water start from the park dock; courses are rectangular loops with four yellow turn buoys and orange sighting buoys placed roughly every 75 meters. A water temperature reading is posted the Thursday before the race; July events typically report water in the low to mid 80s.

Distances offered:

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

The Olympic bike course is technical, routing through town, rolling farm country and a roughly five-mile paved section along River Road, with about 1,250 ft of elevation. The Sprint bike is a rolling out-and-back on low-traffic country roads. Both run courses are mostly flat, out-and-back loops along park sidewalks and back roads with views of the Chesapeake Bay and Susquehanna River. Aid stations provide ice water and Gatorade approximately every mile and mobile support is available.

Event logistics include two packet pickup options (Friday evening and Saturday morning) and a Friday pre-race briefing. All athletes must remain in the park until the bike route is clear; vehicles parked inside the park may not exit until police allow. Visit the organization's website for the most recent information.
