Dress up in your costume and join your friends and neighbors for a one-mile family fun run through Luther Burbank Park, at 10 a.m. on Saturday, Oct. 26. Dogs are welcome, too.

There will be costume contests for both people and dogs, and treats and prizes for all runners/walkers.

Meet at the south end of the park near the beach area. Registration is $12 plus tax; visit www.myparksandrecreation.com and enter course #14367 (there is no cost for children in a stroller.) Call (206) 275-7609 for more information.

After the run, all are invited to head to the Mercer Community and Event Center for the Mercer Island Preschool Association’s annual Halloween party.
