From the Organizer
Join Great Falls TrailBlazers for this annual Fun Run. The run will be on July 4th at 8am. We will meet at the Great Falls Library and leave sharply at 8am. This pet-friendly event is open to all ages. The trail makes a loop and goes through the woods so if you want to bring a stroller it is probably best if it has large wheels like a jogging stroller. This is a great way to kick off your celebration of July Fourth.
