I have been training hard all winter and spring and the early part of the summer. In mid June I got a bronchial infection that totally knocked me down. I'm just now starting to blow a "700" on the meter the doctor gave me. When I was sick I was blowing about a 300. But now I'm wondering what I do. I have been training on the 12 week Trail Half Marathon program and was about halfway through. I'm not even sure how to figure out where to go back to. I'm not running strong at all and anything I do involves a lot of walking these days. Do I start over?
