Spring arrives with a burst in April, delivering 55-65°F running weather. Summer humidity peaks in late July but rarely hits Deep South levels. Fall is the highlight: October foliage, 50-65°F, and crisp mornings that make New England famous for running.

Running Culture in Connecticut

The Hartford Marathon and New Haven Road Race (a Thanksgiving tradition since 1978) anchor the calendar. Connecticut's compact size means trail runners can access hundreds of miles of Appalachian-adjacent trails within a short drive. The Litchfield Hills region offers rolling rural roads favored by collegiate cross-country programs.
