The Chilly Half Marathon follows an out-and-back route that starts and finishes at Newton’s Newton South High School, where runners gather inside before the race start so they won’t have to wait outside too long in the cold before they get started. From there, the course unfolds through Chestnut Hill Village up past Crystal Lake, and crosses over both Boylston Street and Beacon Street. Runners also pass a number of local city parks along the way and get a chance to run past the campus of Boston College.
