Chugger,
I feel for you (see my PF message)
I suppose injuries are as much of the 'running lifestyle' as training, racing etc. it's just how you look at them.
Try and make a positive out of a negative. What will you be able to do now that you can't run for a few weeks? - Chill out?, time with the wife/kids/girlfriend/boyfriend? Cycling? Swimming?
You'll be back sooner than you know it!
Take advantage of the break and come back stronger and hungrier than before.
Good luck.
MH
