All City 20 Miler (10 Miler too!)
About this race
It's that time of year: we're inviting all Philly (and beyond) runners to run long with us!
On Saturday, October 31st - also known as Halloween - we’re partnering with Students Run Philly Style, Team Philly Race Training and the Philadelphia Marathon for the annual All City 20 Miler (10 Miler too)! Whether you are training for the Marathon, Half Marathon or just want to join the long run fun, we’ll have a fully supported course with pace groups and hydration stations along the way to keep you moving and fueled properly. The 20 and 10 mile runs will both start and end at Manayunk Crossing (3720-40 Main St, Philadelphia, PA 19127).
All are welcome to join! Costumes are encouraged and there might be a contest 🎃
** Please note: this is a FREE training run, not a race. Registration is encouraged!
