Exeter Hospital’s 11th annual Trick or Treat Trot 5K will be held on Oct. 29, at 10 a.m. Starting on the campus of Exeter Hospital, teams of walkers, joggers, runners, and hundreds of supporters of all ages, many in their Halloween costumes, will take part in the Jim Dill Memorial Trick or Treat Trot 5K and United In Wellness Cancer Walk. Now in its tenth year, this major event will support the goals of the hospital’s historic Together We Can fundraising campaign to expand cancer care and other vital health care services in the Seacoast region. People of all ages and all abilities can participate. Additionally, there is a Creepy Crawler Fun Run for kids. Costumes are encouraged and prizes will be awarded for best costumes and fundraising achievements. For more information about participating and to register, visit unitedinwellness.org.
