The Medical University of South Carolina is celebrating the American Heart Association's national Start Walking campaign with a local observance Wednesday.

MUSC is encouraging people to bring sneakers to work, take 30 minutes to walk and pledge to live heart-healthy lives.

The walk starts at noon at the MUSC Horsehoe on Ashley Avenue, and there will be walking routes beginning and ending at Colbert Library and the MUSC Wellness Center. Participants are asked to check in at one of those two locations for maps and to fill out a raffle ticket.
