Becky I did the same thing. I trained for my Montana ride in July - was able to ride 80 - 90 miles a day and then when I got back, with all the heat we were having I stopped riding. Now it's like I never trained and did all those rides. I feel like I'm starting over.

There's something about overtraining, peaking and laying off that messes with your body. Just keep riding. It will come back in no time.
