Before trick-or-treating on October 31, run in the region’s flattest, fastest and most fun Half Marathon, the AACR Rock ‘N’ Roll Half Marathon.
This year’s version of the historic race will be full of music, medals and many spooky twists! More than 18,000 runners will not only be competing in the race, but also for the best-dressed costume contest.
This year’s proceeds will be donated to the American Association for Cancer Research (AACR).
To learn more about how to take part as a runner, volunteer or donor, visit the AACR Rock ‘n’ Roll Philly event page.
