You have become the man-to-beat. May be better watch your feet from now on?
i'm beginning to think those horrible days you can't wait til they are over are a precursor to jumping into a new level of fitness. can't wait for last meet ! ten years ago i'd of said 'oh i'm overtrained' and backed off and consequently i never got substantial improvements. some was technique, but some was effort.
if your joint hurts that's bad. if you feel like a slug and aren't going fast you might just be ready to break through to a new level so hang on.
That is a line one wishes to say when 15 years old. For many, saying that exact line would most certainly mean a man in a white coat rolling you back to the bedroom in a wheelchair, and relatives/children seriously discussing with the family physician whether medication should be increased or not, is not that true?
(My apology if I offended anyone.)
Anyway, sincere congratulations. You must feel really great!
