Running is a great form of exercise, but without proper equipment, conditioning, and form, even experienced runners are susceptible to injury. Running injuries can be caused by a traumatic event, but are most often the result of overuse—they happen over time due to repetitive movement. Protect your knees, feet and ankles, shins and calves, hips, and lower back by identifying and learning to prevent common injuries such as stress fractures, ankle strain and sprain, patellar tendinitis, and more.
