Flat & Fast Running Trails
Flat trails are where you run for time rather than terrain — tempo efforts, threshold work, a long run held at goal pace, or a first crack at a race distance. Rail-trails dominate this category for a simple reason: the beds were graded gently for trains, and that grade is still there under your feet. Flat is also the sensible choice coming back from injury, pushing a stroller, or on any day you want the effort to be exactly what your watch says it is.
