THE BEST PHOENIXVILLE RUNNING EVENT (WITH THE BEST MEDALS) DURING THE BEST LOCAL HOLIDAY IN ALL OF AMERICA, IS BACK AND EVEN MORE BLOBTACULAR THAN EVER FOR THE 25TH ANNIVERSARY OF BLOBFEST!

ON SUNDAY JULY 14TH, STEVE MCQUEEN AND YOU STAR IN THE HORROR MOVIE OF THE CENTURY! UH..._LAST_ CENTURY!

Every year, Phoenixville, PA celebrates Blobfest in honor of 1958's The BLOB. And every year, WE THROW A RUNNING PARTY to help celebrate and support the historic Colonial Theatre that stars in the film! This year, in addition to our 5K,10K, and kids' fun-run, we will have a half marathon!

Course Decoration Contest!
Not a runner? Get a group of friends together to participate in our course decoration contest and you could win gift cards to our local Phoenixville restaurants. Here's how it works: Your group will be given an area on the 5K course to decorate in some Blob (or other monster/alien) theme. The only rule is that you don't obstruct or startle our runners. After the race, runners will vote for the best scenes and the winners will receive gift cards!

Paid Parking Near the Start/Finish: See the parking map at the bottom of our registration page HERE.

The other is on the corner of Taylor Alley and South Main Street. There is also parking at the Borough Hall lot (351 Bridge Street) and the Smithworks parking lot (30 N. Main St.). When you park at Smithworks, it's a very short walk over the bridge by the Foundry to get to the starting line.
