I am training for a half marathon in October and have started my training two weeks ago. I used to run as part of my boxing training but gave it up 7 years ago as I broke my arm. I never ran far either, usually 2/3 miles.
However, when I first start to run both knees feel really sore. I carry on though and rather 10 minutes the pain eases a lot or goes away completely.
I am worried that I am doing severe damage to my knees because of this pain. I am a big guy (6ft 3, 18st) but I have the proper trainers for my running style.
Have I hurt something or is there a warm up I could do to ease/solve this pain? I am taking Glucosamine in liquid form and doing various stretches at the moment.
