Put on your best costume and come celebrate with your family along Boise's scenic greenbelt at this festive 5K/1K event starting at 10:00 am from Municipal Park. Little ones on the 1K route get to enjoy trick-or-treating along the way, while everyone can choose to walk or run at their own pace. Best of all, kids 6 and under run free, ages 7-12 are just $12, and teens and adults are $25, with all proceeds supporting Shriners Children through the Daughters of the Nile Foundation.
