Marsh Creek Sprint Triathlon 2025 unfolds on Sunday, September 14, 2025, at the scenic Marsh Creek State Park, just west of Philadelphia, PA. The course begins with a time‑trial swim in the pristine 500‑acre Marsh Creek Lake, followed by a well-paved single-loop 20 km bike route featuring rolling terrain along trout streams and forested back roads. The final 5 km run takes place entirely within the park, offering lake views and a challenging uphill around mile 2. In addition to the individual triathlon, the event includes a Sprint Aquabike (swim + bike) and relay team, plus a collegiate-only division. All categories are USA Triathlon-sanctioned, open to all ages 12+, and timed with chip technology. Athletes receive a race shirt, socks, finisher medal, and post-race refreshments in a well-supported, community-rich setting.
