Warm start, big temp swing, rain likely

Starting at 66°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temps will climb significantly to 81°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. Rain is likely — waterproof your phone and bib, and consider a disposable poncho for the corral. Moderate humidity at 78% is worth noting for effort level, especially in later miles.

Race Info

The Half Marathon starts at the National Museum of the U.S. Air Force on the Saturday of race weekend and heads north to Huffman Prairie Flying Field, where the Wright brothers refined powered flight. The route crosses Area A of Wright-Patterson Air Force Base, leaves the base for the streets of Fairborn, then turns south past the Wright Brothers Memorial. It re-enters the base through Area B and finishes beside historic aircraft in the museum's Air Park.
