Sparta Half Marathon
Race Day Weather
Comfortable temps, warming through the race
Starting at 64°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temperatures rising to 75°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 68% is worth noting for effort level, especially in later miles.

Race Info
The Sparta Half Marathon is an annual race in Sparta, Wisconsin, run as an out-and-back combining the flat, gravel Sparta-Elroy State Trail with rolling paved country roads outside town. The race starts and finishes at the Sparta Area Chamber of Commerce building and also offers 10K and 5K distances. Despite a 2026 relaunch on a new website and registration platform, course records referencing 2023 confirm this is an established annual event rather than a new one.
