They come from one thing more than any other: adding weight faster than the body can adapt to it. Here is how to keep that from being you. Your body adapts to load in weeks, not workouts The muscles get strong fast. Tendons, ligaments, feet, and lower back? They take two to three weeks to catch up to a new load. If you add 10 lb to your pack today and ruck three times this week, the muscles will handle it. The connective tissue will not, and that is where the injury starts. The Ruckfecta rule is simple: add no more than 2 to 4 lb every two weeks. That sounds painfully slow on day one. It is also the difference between rucking for a year and rucking for a decade. The injuries you actually have to worry about In ten years of coaching racers through training cycles and races, the injuries I have seen the most are not the ones beginners worry about. They cluster in three places: Ankles and feet. Almost always from a mis-step on uneven ground — a curb, a root, a rock hiding in tall grass — late in a ruck when you are tired. The fix is not bigger boots. The fix is stronger feet and better awareness when fatigued. Shins. From doing too much, too fast, on hard surfaces. Concrete is brutal. If your shins start barking, swap a road ruck for a trail ruck or a…
