65% of runners will be injured in a given year. Runners will miss about 10% of their scheduled workouts due to injury. The best predictors of running injuries are:

• High mileage
• Beginners
• Competitive runners
• Previous injury

Previous injury is the best predictor of future injuries because 50% of running injuries are a re-occurrence of an old injury.

Running injuries are a result of:

• Genetics (lower limbs)
• Environment (shoes, training surface)
• Training methods (overuse)

Training methods account for 50-65% of running injuries. This includes doing:

• Too much (more than what your body is presently capable of)
• Too soon (greater than 10% increase in weekly and long run mileage)
• Too often (consecutive running days)
• Too fast (recovery and long slow distance runs)
