Boston Marathon
Boston Marathon is a hilly marathon in Boston, USA, held each April. A net-downhill start that punishes quads, then the Newton hills from ~26K capped by Heartbreak Hill. April in New England swings widely — anything from near-freezing tailwinds to unseasonal heat. Boston's hills change the plan itself: expect hill repetitions and long runs that rehearse the course's shape.
