It's not possible to give a personalised advice on injury without seeing a qualified practitioner. Following one of our training plans may help you to avoid injury as the training increases gradually enabling you to adapt to your current load before moving on - the reason so many people do get injured. Another common cause of injury is ill fitting footwear. A good specialist running shop will be able to analyse your running style and advise on appropriate footwear.
