The Marsh Creek 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 time trial 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.

The parking lots exit directly on to the bike course and we need to make sure the course is clear prior to allowing 500 cars on the road. Thank you for your understanding and patience in this matter.

Thank you for making this event your first triathlon! There are many more people like yourself who will be racing this type of event for the first time. Please note that we no longer have a Novice category/division. We now start all of our races with a time trial start (One at a time) so you can start the race where you feel most comfortable. We do however have what we call a nervous swimmer swim cap. If you are nervous about the swim make sure to ask for the nervous swimmers cap at packet pick up.
