Cool but Ideal Marathon Conditions
It will be cool with lots of clouds and very little wind at the starting line, in Hopkinton. Temperatures will be in the middle 40s. As the runners make their way into Boston temperatures will stay cool with a very slight, easterly, head wind. temperatures in Boston will stay mainly in the lower 50′s, as the runners cross the finish line.
If you’re going to Boston to cheer on the runners or you’re heading to the Sox game make sure you dress warm. Good luck to all the runners. Dan Brown
