Kiddie Corral (Free Child Care)

We’re happy to provide free on-site child care in our Kiddie Corral for the children of 5K participants. Potty-trained kids through elementary school age are welcome. Since the Kiddie Corral is outdoors (with bathrooms inside), please dress your child for the weather. To keep things safe for everyone, we don’t provide snacks. A parent or guardian must stay on-site while their child is in the Kiddie Corral — the entire 5K course counts as on-site.
