Weather Update and Course Impact

On race week, it looks like it will rain mid-week, then clear up with sunny skies but a cold morning in the 30's, rising to a sunny 50's by mid-day.

Depending on the severity of the rain, this means that the trail may be a tricky combination of mud in places and frozen dirt ruts in other places.

Especially with the possibility of overnight ice, be mindful of footing on the rocky sections. We've put together advice on how to run the marathon here and how to run the half-marathon here.

Details on the 5k route can be found here -- much of the route is the paved Arizona Trail Greenway, so be sure to manage the curves and hills safely, especially if there is ice or slushy puddles in the early morning.
