Half Marathon
The half marathon is the distance where joggers become runners. With 2.1 million finishers annually in the US, it's the preferred distance for 35% of runners — demanding enough to require a real training plan (12-16 weeks), short enough to be achievable within a single season. The 13.1-mile distance builds genuine aerobic endurance and teaches race-day pacing, nutrition, and mental toughness that carry into every longer challenge.
