During the Novant Health Charlotte Marathon, there are a lot of runners who will grab your attention. One group, though, has its own division. This group honors the armed forces by walking the entire 13.1 miles of the half-marathon wearing weighted backpacks, or “rucksacks.” It’s the basis of military training. Rucking is a great workout for building strength and endurance, but mentally, it’s even more than that. It’s been called, “movement with a purpose,” and Michael Sweeting is heading up the Rucking Division of the Charlotte Marathon this year.
