I have been time trialling/MTB/Cyclo-cross racing for many years. I started running four or so years ago, but apart from entering half marathons with little training it wasn't particularly regular. It became more regular two years ago with only calf pain which soon went.
I altered my pedalling style gradually from that point, but almost a year ago started getting hamstring problems in my right leg. It took me a long while to work out that this was because trying to get close to 360 degree pedalling I was favouring my right leg. For the last 6 months I have been doing more specific stretching (always stretched regularly as I used to do martial arts) and attempted to cure the problem by more regualr short runs and massage.
I'd just like to know if thos who do duathlon or even triathlon have suffered or know someone that has suffered the same thing. It's very frustrating. I think I am aware of the problem and what to do, but I'd be interested to hear.
