The Health and Fitness Expo, now in its sixth year, hosts more than 80 vendors in the Pennsylvania Convention Center. This event is a must on everyone’s list, runners and fans alike. All race-weekend participants will need to stop by the expo to pick up their race packets. Fans and runners may purchase official 2012 Philadelphia Marathon merchandise while supplies last, and visitors to Philadelphia will get information about Philadelphia attractions, restaurants and activities here as well.
