From the Organizer
Whether you’re gearing up for your first race, using DoLittle as a training run for a big fall goal, chasing a PR, or just looking for a smooth race-day experience, this race is built for you. The course uses the flat and fast Lake Country Trail, giving runners a scenic, smooth, and speedy route with plenty of room to settle in and run smart.
🤔 What’s with the name? You know… Do a little marathon. 😉 Run a few miles, run the full 26.2, walk, ruck, or choose The RAD — Run Any Distance option. However you show up, we’re here for it.
This is not just flat. It is laser-flat, lightning-fast, and fully certified — a course designed to reward steady pacing, strong legs, and smart racing. It is also extremely spectator-friendly. Your fans and crew can see you multiple times throughout the race without turning the morning into a county-wide scavenger hunt.
If you are ready for a high-energy, runner-first event with speed, support, live tracking, great vibes, and a finish-line moment worth chasing, lace up and join us. This is the race that shows up.
