Bay State Marathon
The Baystate Marathon, held in mid-October in Lowell, Mass., produces a higher percentage of Boston Marathon qualifying times than any marathon besides the Boston Marathon itself. The flat, double-loop course is the main reason. The weather is usually close to perfect—dry, with temperatures in the 50’s. Although there are often blustery fall winds, you’re never heading in the same direction in the Bay State Marathon, so they aren’t as frustrating as headwinds on point-to-point and out-and-back marathon courses.
