The Run Fest was formerly the ODDyssey Half Marathon in which people dressed up in costumes and run! I couldn't imagine running in costume in a June Half Marathon but this race was just as fun without a costume!! If you aren't ready for a half marathon just yet, there is a 5k race or half marathon relay. The courses are amazing- the 5k is nice and flat and finishes on MLK Drive. The half marathon is not your typical Philly Half race going throughout the city, this is basically all in Fairmount Park, there is sections on Kelly Drive and MLK drive some sections are hillier than others which adds to the fun. There was so much course support with the aid stations run by one of my favorite local non profits, Students Run Philly Style giving out fluids and gels! The expo was held at a local brewery, Yards and sponsored by On shoes. The after party was awesome with a photo booth, Yards beer and lots of games. Though I am not a summer runner, it wasn't too hot the morning off and there was plenty of shade and I would absolutely run it again!
