Clarksville Half Marathon
Race Day Weather
Cold start — layer up, big temp swing
Runners will start in chilly 40°F conditions — dress in layers for the corral and plan to shed early. Temps will climb significantly to 57°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. Moderate humidity at 67% is worth noting for effort level, especially in later miles.

Race Info
The Clarksville Half Marathon and 5K starts and finishes on Franklin Street near Public Square in downtown Clarksville, Tennessee. The race began in 2024 with a half marathon, 5K, and 1-mile option, then added ruck divisions in 2025 requiring a 30-pound pack for men and 20 pounds for women. The 2026 race, its third running, uses a new course route through the city.
