Marsh Creek Sprint Triathlon
The Marsh Creek Sprint Triathlon is staged at Marsh Creek State Park near Philadelphia, PA, centered on 500 acre Marsh Creek Lake. The event offers triathlon and aquabike race options with the following distances:
- Triathlon: 750 meter swim; 20K bike; 5K run
- Aquabike: 750 meter swim; 20K bike
The swim uses a single rectangular loop inside the lake with two yellow triangle buoys to mark the course and orange round buoys for sighting every 75–100 meters. Water temperatures are typically in the low 70s and wetsuits are expected to be legal; a preliminary water temperature is posted the day before the event and an official reading is taken by USAT officials on race day.
The bike is a well paved, single-loop 20K route with all right hand turns, rolling terrain, a few technical sections, and an elevation profile around 1,059.7 feet. Athletes return to the park to enter transition for the run.
The run is a one-loop 5K entirely within the park with lake views, an uphill near mile 2, aid stations roughly every mile, and a final half mile across grass into the finish area.
The race is USA Triathlon sanctioned. Race categories include Overall, Masters Overall, Age Group, Aquabike, Military, Clydesdale, Athena, and Relay Teams. All participants receive race apparel, a finisher medal, post-race food and drink, and event photos. Packet pickup requires photo ID and swim clinics are offered at the lake by a local swim provider. No open swimming in Marsh Creek Lake outside official activities is allowed. Visit the organization's website for the most recent information.
