New England Green River Marathon
Race Day Weather
Warm finish, adjust pace wisely
Runners will face a temperature rise from 62°F at the start to 77°F at the finish, with humidity averaging 70%. A light wind from the WNW will create crosswinds early, shifting to a tailwind from miles 3 to 7, then returning to crosswinds and headwinds in the latter stages. It’s advisable to pace conservatively early on and hydrate frequently as temperatures increase, especially in the warm finish.
This course drops 1,457 ft from start to finish, so we look at it at 3 points, not just the start line. In a typical year, at 9:00/mi, you start at 62° and finish around 10:55 AM in 77°; typical start-line conditions say 73° then.
