NYT: An early-morning workout flash mob is known as the November Project, which began in Boston in 2011 and has since spread to 19 cities in the United States and Canada. It’s a point of pride that the group — not quite running club, not quite boot camp — defies categorization. It blends the intensity of CrossFit, the cultishness of SoulCycle and the weather agnosticism of a Polar Bear swim with the high jinks of an obstacle course and the camaraderie and accountability of a sports team.

Workouts in Boston have drawn more than 1,400 people, among them Olympic and professional athletes.

After you done, you hug a member of the flash mob.
