Before folks even start running, they'll have opportunities to get colored up and receive lots of glow goodies. People can arrive in costume and warm up with a "Thriller" tutorial. After the daylight goes, the black lights come on, and foam fills the after party. From 2 to 5 p.m. on Oct. 31, there will be a festival with games, inflatables and face painting for kids and families to enjoy. Admission is $2, or free for those who participate in the 5K or 1-mile fun run.
