Join Denver Celiacs for their 13th annual 5K celebration at Clement Park in Littleton on Saturday, May 16, 2026, starting at 9:00 AM—a family-friendly event that welcomes strollers, dogs, and kids while supporting awareness of celiac disease and gluten-related disorders. You'll loop around Johnson Reservoir twice with stunning foothills as your backdrop, plus enjoy the ROCK Fun Run, food trucks, samples, giveaways, and activities for the whole family. Head to shelters J, K, and L starting at 8:30 AM for registration, and look for the entrance arch and Denver Celiacs' white tent to get going!
