- Glacier Glow is a nighttime 5K glow run suitable for all ages and abilities. Friends and family can run as a team or individually through the streets of charming Columbia Falls, looping through River’s Edge park and back to the Coop for a sparkling party. Glow Zones will energize runners along the course. A light show and DJ will keep the fun going at the end of the race. Beer, wine, and soft drinks will be available and Columbia Falls’ yummiest food carts will be on hand to serve the crowd. The run will start as soon as it’s dark, around 8:30.
