Wayfarer is spot on, I've found the key to getting the right training balance is quality sessions. If your on the road 6 times a week and in the gym too 3-5 times a week are those 9 or more "training" sessions quality ?
I was doing a similar type of schedule and got to the point where I wasn't burn't out, I just could give enough to those key sessions.
It seems to work for me, I just make sure I'm rested and can give what each session requires. If its speed or a long run these are key for me. Recovery runs or active rest I don't need to give as much!
My point is make sure every session you do is quality.. As far as I'm concerned it doesn't matter if you run 5k's or Marathons quality training is the key.
The title speaks for itself really. My girl friend is looking for a running club to join who are based/train in or around Greenwich or Blackheath. We have found various clubs in the south of London (New Eltham being the closest) but none seem to train or be based around Greenwich or the Heath. Shes hoping to find an informal club where she can make good progress but more importantly run with other similar ability runners.
I'm not too sure about knee supports when running. When I was playing rugby I wore one for a season due to injury and this was helpful to provide stabilty due to the vast range of movements, but for running I'm not sure. I try not too, you may just mask the problem and you can become dependant on them.
You could however try alternating sessions, one with the supports and one without. This way you may get some stability but not become dependant or mask an injury. But I'm told its best to attack the root cause, if you have ITBS, runners knee, or anything else theres usually a good reason and rest, ice, stretching, new shoes etc.. can solve the problem. A knee support will warm your knee and that can be a bonus now its colder. ;o)
On shoes its best to check if you can. Weight training can be very helpful to stablise your joints by strengthening complementary muscle groups. I spend a couple of sessions in the gym each week when I can, but you can also do this stuff at home. Leg lifts, squats etc...
