I came down with something similar two weeks ago and it killed my goals for late April and May. I came off of San Dimas feeling like I was flying, looking forward to Devils Punchbowl then bam this thing just sapped me. Two weeks off the bike and now I'm getting back to training. Moved my goals from Devils Punchbowl and the State RR's to the big crits in June and July. Sucks, but there is still a lot of racing left this year.
