Kinetic Multisports

Premier Triathlons on the east coast, offering exceptional quality and value


The MarshMan Sprint Triathlon is an amazing race in a beautiful location. Staged out of Marsh Creek State Park, this race is located just west of Philadelphia, PA and minutes from the Turnpike. The swim takes place in 500 acre Marsh Creek Lake and features a single loop, rectangular shaped swim course. The bike course is a beautiful, well paved, single loop 20k course that takes athletes through a mix of technical sections and long straightaways alongside trout streams and forests. The new 5k run course is entirely within the park and has beautiful lake views and a good uphill at mile 2. There is a ton to see and do outside of the race with kayak rentals, great restaurants and rural, back country roads.  Click HERE to learn more and plan your trip.

Course Details

Swim: The swim is a rectangular shaped course tucked into crisp, clear waters of 500 acre Marsh Creek Lake. There are two (2) yellow triangle swim buoys on the course that athletes will go around. There will be orange round buoys for sighting placed every 75-100 meters. We expect water temperatures to be in the low 70’s on race day; definitely wetsuit legal. We will post a preliminary water temperature the Friday evening prior to the event with an official reading taken and posted by our USAT officials race morning.

Bike: The Marshman bike course is epic. Well paved roads, great scenery and trout streams welcome cyclists as they race around the lake and its watershed.  With all right hand turns, this course feels like a racetrack through the forest with a rolling combination of false flat with a few technical sections that will get you out of the saddle.  This an honest course as it rewards bike handling skills and the endurance of the hard charger.  However, it is also a lovely course with uphills and forested valleys, hence perfect for the slower athlete as well. Athletes will do one (1) loop of the bike course and re-enter the park for T2.

Run: The run course is a 1 loop, 5k course throughout the park.  The first mile weaves through the boat ramp area before heading to the upper section of the park near the park swimming pool. Then it loops back around the race site, continuing along the lake to the finish line. The running trails are well maintained and there are aid stations every mile. The last half mile is through the grass and pops out in front of the finish line. The September views along the lake are amazing, you can’t race this race just once.

Duathlon: The Duathlon will start with a 1.25 mile run and will start at 7:30am with the first wave of the Triathlon.  The first run will start near the finish line and will be an out and back run to end at the Transition Area where the swimmers come in.  The Bike and Run courses are the same as the Triathlon.
