The Schuylkill River 50k Relay & Ultra Marathon

Lace up for an unforgettable journey along the picturesque Schuylkill River Trail at The Schuylkill River 50k Relay & Ultra Marathon, set for Saturday, April 25, 2026, in Mont Clare, PA. This popular event caters to both seasoned ultrarunners and relay teams, offering a flat, supported, and easy-to-navigate course ideal for chasing a personal best or tackling your first 50K. Starting and finishing at the historic Lock 60 on the Schuylkill Canal, the scenic out-and-back route guides runners through lush forests, alongside the tranquil canal, and past stunning river views, extending all the way to Conshohocken and back. You'll traverse beautiful Montgomery County and experience the natural charm of Valley Forge National Park.

Participants can choose to conquer the entire 50K distance solo or team up in a 3 or 6-person relay, making it a vibrant celebration of camaraderie and determination. Aid stations are strategically placed at each relay transition point, providing ample support for all runners, with Ultra participants also benefiting from drop bag service. Typical race day conditions in late April offer comfortable highs around 66F and lows near 44F, with only a 14% chance of precipitation. The race features staggered starts to ensure runner safety and minimize trail impact. Celebrate your achievement at the lively finish line festival at Saint Michael's Park, complete with live music, delicious food trucks, and a refreshing Sly Fox SRT Pale Ale, where Ultra finishers earn a custom belt buckle and relay members receive unique neck medals.
