Relay For Life is an annual fundraising event hosted by the American Cancer Society. The event is held in communities around the world to raise money for cancer research and patient services. Participants form teams and take turns walking or running around a track or designated path. Each team is asked to have at least one member on the track at all times during the event. Other activities, such as music, games, and food, are also included as part of the festivities. Relay For Life events typically last anywhere from six to 24 hours, depending on the location.
