Going backwards fast!

I think those 3 weeks missed pounding the streets has well and truely set me back. I can't believe how badly I'm struggling with my long runs. Before Christmas I was a consistent 11 min miler when doing a double figure run, now I'm lucky to do 12. Rather worrying, serious work to be done and I think that means cross training twice a week. Really need to find a decent but cheap place to train. It was 12 weeks today, oh my. Thinking I need a miracle!
