Have been upping my mileage recently but not overly so but last few runs have felt a twinge at the top of my left calf behind my knee, happens at stat of run but goes away fairly quickly but I am noticing that I fel twinges when not running so have been massaging and there is definately some soreness there, booked in for a sports massage so hopefully that will help, but have half-marathon in 4 weeks so don't want to reduce running to much, but may have to reduce back on my miles.  Anyone had anything similar

Hi Robert, I'm on for my first half marathon in a couple of weeks and I tend to get sore knees and sometimes calves after my long run (over 13 miles), the important thing is that I then rest completely for a day and a half, after which I resume my training probably with a 6 mile jog at easy pace.

I also do the frozen peas thing after my long run, although I must say it seems to work better with frozen sweetcorn ;-)
