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

The BEST Phoenixville running event (with the BEST finisher's medals) during  the BEST local holiday in all of America, is BACK for 2026! On Sunday July 12th, 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! Join us as we start and finish right in front of the Colonial Theatre for our 5K, 10K, Half Marathon, and Kids Fun Run!

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!

Location: The race starts in front of the Historic Colonial Theatre on Bridge Street! 227 Bridge St. The street will be closed to cars.

Parking: Free off-site parking will be available at Phoenixville Middle School ( 1000 Purple Pride Parkway ). A free shuttle bus will run from 6:00 am to 11:00 am.  5K and 10K runners are encouraged to park at the middle school. Half marathon runners should park at the middle school only if they have picked up their bibs the day before (since the half marathon starts at 7 am). GPS LINK TO LOT

Paid Parking Near the Start/Finish:   See the parking map at the bottom of our registration page HERE. Every year it seems like there is less and less parking in Phoenixville (and now most spaces cost $$ on Sundays), so we STRONGLY ENCOURAGE CARPOOLING (or walking to the start if you live close by). There are four municipal lots near the starting area. One is accessible by the driveway between the Municipal building and the Foodery (325 Bridge Street). 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 up to Bridge Street. Finisher's Medal: Every finisher in the 5K, 10K, and Half Marathon will receive an incredible Blob-themed finisher's medal!

Flexible Options: If you register for the half marathon but the day comes and it is very hot (or for any reason), you can drop down to the 10K or 5K. Just tell our timer at the starting line.

Pacers :   2026 pace times for the half and 10K will be available as we get closer to the race!
