Wineglass Marathon
Race Day Weather
Cool start, warming finish
Runners will face a cool start at 48°F with a gradual warm-up to 63°F by the finish. Winds will be a factor with consistent headwinds during the middle sections, particularly from Miles 3-8 and 10-25, reaching up to 10 mph. With humidity at 75%, a conservative pace is recommended, especially in the exposed stretches to manage exertion. Pre-race conditions will feel as low as 44°F, suggesting a light layer for warming up.
The finish is 19 miles from the start, so we forecast it at 2 points, not just the start line. At 9:00/mi, you start at 50° and finish around 12:10 PM in 60°.

Race Info
Welcome! The course is fast. Very fast. Personal records tend to fall here. Beyond the chance for a PR, the speed also makes Wineglass one of the top spots to qualify for the Boston Marathon. And the early autumn scenery is stunning. These are just a few of the reasons runners love the Wineglass. Source
