The 9th Annual Blobfest 5K, 10K & Half Marathon! 2026

The 9th Annual Blobfest, Phoenixville's premier running event, takes place during a local holiday. This race supports the historic Colonial Theatre, where Steve McQueen and you star in a horror movie. Start and finish at the theatre to earn a Blob-themed finisher's medal. Non-runners can decorate a 5K course section for a chance to win gift cards. A kids' fun run is available, and runners receive 10% off at Steel City Coffeehouse afterward.
