LOCATION CHANGE: The Chill 4K is Switching to Swords Park!
The Chill 4K is moving to Swords Park this Saturday, December 6. Due to current conditions at Riverfront Park and the weather expected later this week, the Riverfront trail (not plowed) is likely to be icy, uneven, and unsafe. Swords Park has been plowed and offers a more predictable surface for running.
