I walked this race with my Mom, and we both had a great time. The out and back course is really lovely. You start out by the Washington Monument fountain, run (or walk like we did) along the Schuylkill River and end with a quick uphill by the Rocky Steps. The race is organized in a way that makes it easy for runners to run the 5K and then loop back around to do the 10K, too, if they so choose. Rock'n'Roll always has great swag at the end of the race. There were bananas, hummus, chips, and soft pretzels (because apparently Philly is known for their pretzels). They should give out bags for all that post-race swag! I would definitely do this race again and would love to run it. In good weather conditions it'd be a fast course!
