Runners should plan accordingly, as the first widespread freeze of the season appears imminent for Sunday morning.

"Most of the major metro areas should expect what we would call a light freeze, generally at or above 28 degrees," the weather service wrote in their forecast briefing on Thursday. Temperatures will climb above freezing by 9 a.m., reaching the 50s by 1 p.m., and topping out near 60 later in the afternoon.

When do road closures begin in downtown Austin?

Race officials said road closures will begin as early as 3 a.m. Sunday, though most will start around 6 a.m. Streets are expected to reopen gradually throughout the late morning, with most roads being reopened by noon. Some downtown roads will close earlier and reopen later due to event staging.
