I had a right leg ankle surgery two years ago.There is a rod fitted in my leg.My doctor has advised me to start running but I don’t know how to start practicing.I want to take part in my Annual School Sports which is on november 2012.
It would depend on how fit you are and what your abilities currently are. some people with injuries to there legs can actually run easier than they can walk or jog as this puts more pressure on the downward step than running.
I would recommend you do not start running on roads but on grass in a park as it will cushion things a bit. I would make a point of having good running shoes too. Again to cushion the impacts.
It can be that just running 25 meters to start with would be good turn walk back and keep repeating this till your tired. If you only manage a few then have a longer break and try a few more.
Tread mills can also be good to get started on again the impact tends to be lower on the running surface so possibly better for your leg.
