My current CTL is 63. I am tapering right now until the 13th. Got a up hill TT on this Sat. Will be short (25 minutes??) and the effort would not tire me out. Roughly 10 days before the targeted event. It seems that once my CTL reaches to 50 I feel like I have lost some fitness. I seem to feel better at 50 to 55. I guess I should try to maintain my CTL above 50? If so, what kind of workout I should be doing??? I have already nailed total of 6 sessions of vo2max workout over the past 2 weeks. In order to prevent my CTL from dipping too low and yet not tiring myself, should I do threshold work twice in the week? After the up hill TT on Sat, on Monday an hour of threshold work? And another one on Friday? If I ride too easy and too little from Sat to the 13th, my CTL would reach to 45 with a TSB of 30+. Or I can just commute to work for couple of days. A single commuting day I can rack up 100TSS though.
