Over 2 decades of working as a Sports Physio, I am always asked to try and identify exactly why my patients develop overuse injuries. This is often a difficult task due to the number of factors that can combine to cause an injury. What I have noticed is five mistakes that endurance athletes seem to make, whether they be professional cyclists or triathletes, or new exercisers training for a fun run. I can assure you, I have personally made all 5 of these mistakes. They are not exclusive to males or females and avoiding these mistakes will help keep you fit and well.
