Warm, humid weather expected to challenge runners during Cowtown Marathon
Runners in this year’s Cowtown Marathon will face unusually warm and humid conditions, with temperatures climbing into the 60s during the races on Sunday and reaching the low 70s by midday, along with a steady south wind. Meteorologists say the warmth, humidity, and breezy conditions are atypical for late February and could challenge runners on what is normally a cool, fast, Boston‑qualifying course.
