The Mighty Dog 10K & 5K Trail Runs 2027

The Mighty Dog Trail Runs take place in March on the trails at Granite Beach, within Folsom Lake State Recreation Area. Runners, walkers, and their dogs can choose from 5K and 10K run options, or dog-friendly walk options. The 10K course consists of two 5K laps. This event is designed for participants running with dogs, not simply for those bringing pets. Dog divisions are based on size, and a Cani Cross category is available for teams using a run harness. The event also features the Mighty Mile for senior dogs. Aid stations are located at the halfway point of each 5K loop, approximately 1.5 miles in. They provide cold water, FLUID electrolyte drink, and Hammer gels for human participants, along with water for dogs. All finishers earn a medal, and dogs receive a tag. Additional dogs can be included in a walking entry and will receive their own tag and a goody bag. The series has been held for over ten years, with rules emphasizing the separation and untangling of teams on the course.
