Comfortable temps, big temp swing, chance of rain

Mild 53°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 68°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 67% is worth noting for effort level, especially in later miles.

Race Info

The Half Marathon runs 13.1 miles out and back on the Frisco Highline Trail, turning near North Farm Road 65 at mile 6.55. The surface is fine crushed gravel on a former railroad bed, with gentle grades and a few bridges, so it is mostly flat. It is USATF-certified and starts and finishes at Willard Middle School on the Saturday of race weekend.
