Nooooooo! Oh, man, that sucks. I'm currently trying to get all that running fitness back from when I was down with my ITB/periformis issues, so I sympathize mightly with the feeling watching all your hard work slip away. Funny, I didn't even know I had running fitness it until it suddenly wasn't there anymore.

I hope the foot heals extra fast. At least I hope they get you off crutches soon. *hugs*
