A friend of mine has recently taken up running aiming for a marathon at the end of the year. He is a fairly fit guy having played lots of sport for many years but is suffering at the start of runs with a painful inner knee.
It has been just the one knee (right) so far although today's run affected the other knee (left). He finds it painful for the first 5 minutes or so and he adjusts his stride to lessen the pain. Once he is five minutes in to the run he feels ok but is worried that he may be doing some damage and is wary of increasing his mileage as a result.
I have no experience on this and wondered if anyone else had heard or felt this when starting out running?
