Families and friends will gather for the Northern Tarrant/Keller Relay for Life to support the American Cancer Society at 6 p.m. May 30 at the Keller ISD Stadium, 500 N. Pate Orr Rd.The event features relay teams with someone running or walking at all times.The idea of an all-night event comes from the fact that “cancer never sleeps, so neither will we,” said Cheryl Parten, Timberview Middle School teacher and relay event chairperson.At least one team member must remain on the track from 6 p.m. to midnight. Supporters can join a team or sponsor a luminaria to honor a loved one who has died of cancer or has survived the disease. This year’s event is a Mardi Gras theme called “Unmask a Cure,” and the evening will include a night on the track filled with games, tents, booths and music. The relay event will start with an opening ceremony honoring anyone battling cancer. After that ceremony there will be a survivors lap and caregivers lap, followed by a luminaria ceremony for those who died from cancer and then a closing ceremony will end the night.Zero Gravity, a local band made up of middle school students in Northeast Tarrant County, will provide the live music and entertainment throughout the night.Get more information at kellerisd.net. Participants can sign up for a team, dedicate a luminaria or make a donation to the event or to the American Cancer Society. —Staff writer Sandra Engelland contributed to this report.
