Running

Soooo.... after fucking my knee(well, I suspect the muscles above and below the actual joint) a couple of weeks back by sprinting at the end of a 13ish miler, I took a week off. Ran a very gentle 5miles yesterday and the pain came back towards the end(although it was twinging for the last couple of miles). Can't afford physio etc so trying to rest and ice as much as I can, although work also gives my body a kicking all day.
Paris is still 50+ days away. Can I afford to take 2weeks off running at this stage in the game to allow it to settle again properly? Current longest distance is only 16miles but suspect the 18miles I'm supposed to do this weekend might do some actual damage..... Can keep up the r.i.c.e and get as much yoga/squats in to hopefully strengthen the area but worried at the moment if I go for a proper run I'll batter myself...

Do you know what injury you have? Runner's Knee, IT Band syndrome etc.. I think a proper diagnosis is vital.

For time-off, according to this, in two weeks you won't lose that much;

I'd use the time to cross (and strength) train if I was you (as long as it does not hurt). The elliptical running machine is good or just cycle/swim. Do you have a foam roller?

I just got back from over 3 months out from a patellofemoral issue. During the summer I was doing 50-90k weeks and then I couldn't run a kilometre without pain. I had some IMS acupuncture done and did two months of strength training. Now I like using elliptical to push up my milage without the constant pounding of running. In Istanbul there a very few nice mud trails, it's all concrete costal paths. For example, today I did a 5k at 90% on the treadmill and topped it up with a 20 minute elliptical "run".
