I've had shin/knee/foot problems that are due to tight hamstrings; and trying to do too much to soon. I joined a club in 2010 and after about two months the pain started.
It's took me well over a year to be properly diagnosed; spent a fortune on new shoes, knee supports, insoles etc but what made a difference was going to into 'running rehab'. Turns out it was my technique; I was all over the place as a result of chondromalacia meaning I was moving my weight away from my bad knee which, in effect, I'd made lazy and hence short hamstrings which gave me pain in my shin.
Even though I initially tried running through the shin pain eventually my other knee and sometime the foot would go numb.
I'm now on the road to recovery but it's taking ages and just this week the pains have returned so it's back to square one, yet again.
I'd already decided not to race this season, other than club handicaps, as going too fast puts my legs under pressure. This means another year of not doing proper races, and I'm realising I'll probably never be able to do the big events I was hoping to do, mostly fell races.
But I am 46 so I know I'll never be up at the front of the field. I try though, and rarely give in, which is why I've been injured!
