Nov. 1: The Orioles, OriolesREACH and manager Buck Showalter and his wife, Angela, are joining forces with KidsPeace to host the fifth annual Trick-or-Trot 5K/1-Mile Walk, a Halloween-themed race to benefit children in foster care. The race will begin and end at Oriole Park. Costumes are encouraged, and prizes will be awarded for top runners, age-group winners, fundraising teams and best costumes. The registration fee is $35 through Oct. 27 and $40 on race day. Register at kidspeace5k.org. All proceeds benefit KidsPeace Foster Care and Community Programs of Maryland and Washington, including KEYS (KidsPeace Empowering Youth to Succeed), a program that prepares youth for independence through life-skills training.
