You don't realize just how exhausted you were until day 4-5 of a rest week. Well it is day 5 of my rest week and I feel pretty awesome, good enough that I think I went a bit too far with things. I am coming off of a 5 week block and the last two days were a combined 550 TSS, but in any case my TSB on Monday was -41!! Now this may be a bit deceiving because I have a feeling that my FTP has increased, so some of the latter TSS may have not been reflective. In any case I felt like pure hell Monday and truthfully my legs still are not 100%. I still felt productive the last two weeks of the block, at least on the bike. However, my mind was slow and my wife said I was in a constant fog, doing anything beyond sitting on the couch felt like a chore, and I found myself really irritable. In either case I think I will avoid going this deep EVER again, it just ruins me as a person, not so much on the bike, but hell who cares about that if you feel like trash all of the time!! So how low have you gone?
