Madison, WI – Marathon runners in Madison will need more than endurance on Sunday — they’ll need layers. The annual Madison Marathon kicks off under partly sunny skies, but temperatures will struggle to climb above freezing, with gusty north winds making conditions feel even colder.
According to the National Weather Service, race-day highs will peak near 32°F, but winds around 15 mph — with gusts up to 25 mph — will cut into warmth. There’s also a slight 20% chance of snow showers after 1 p.m., which could affect later finishers and spectators lingering along the course.
Though the race route avoids UW-Madison’s main campus, nearby roads will be restricted or closed off, impacting travel through downtown and surrounding neighborhoods. The UW–Madison Police Department is urging drivers to avoid the area or plan for significant delays.
Runners should dress in moisture-wicking layers, cover extremities, and stay dry at water stations. Spectators are also advised to prepare for long stretches of wind exposure.
Marathon organizers have not announced any course changes, but more updates are expected Sunday morning if conditions shift.
