Slopeside Slumber Party

The Slopeside Slumber Party is an exciting running event scheduled for August 16, 2025, at Roundtop Mountain Resort in Lewisberry, PA. Participants can choose between a challenging 3-hour race on a 1.5-mile loop with significant elevation gain and a fun kids' race. The main event offers runners the chance to complete as many loops as possible, with amenities including a fully stocked aid station, real bathrooms, and food for sale.

The kids' race features a shorter, hilly course. The event encourages a festive atmosphere, with participants often donning pajamas or creative outfits. Registration is limited, and the event supports the York Road Runners Club. Visit the organization's website for the most recent information.
