Relay for Life is the signature fundraiser for the American Cancer Society. It’s a team fundraising event where team members take turns walking around a track or designated path. Each event is 6-24 hours in length and each team is asked to have a member on the track at all times to signify that cancer never sleeps. Cancer patients don't stop because they're tired, and for one night, neither do we.
