10th of July I did a two-day endurance event (250km + 160km). Then, I had 3 weeks vacation in which I mostly did zone 2-3 and chill out. I did structured training plans for the whole year up to that point (mostly SSB → base → SSB mid volume). But I was also overtrained for about a month (evidenced by HR and HRV and RPE), so I scaled back for the last 5 weeks and did mostly endurance with some VO2’s to keep my fitness, but rest a bit more (less IF, not TSS necessarily, overall).
Nov 2020 my FTP was 225, before 10th July 245, now Sep 2021 it is 238-240. I am 33, I always do MV plans and endurance rides (2 per month in any case, 120-200km. zone 2-3). Been doing TR for about 2 years.
My ability to do threshold on the trainer went down in 5 weeks, but not zone 2 or VO2Max.
My primary goal is to raise my endurance watts for 8-12h rides. My goal is to ride centuries with ease, and I am training for a double century (200mi).
I have the feeling I am doing something wrong or that perhaps, after all, TR may not be for me given the little gains and the proneness for overtraining I seem to have with - at least the old - MV SSB build plans.
I basically see three options now:
(1) build stronger aerobic engine: try POL 6 weeks MV, extra endurance rides on sunday. But 16 min threshold intervals scare me now.
(2) build stronger aerobic engine: do sweet spot base 2 MV
(3) see whether I can do another build immediately (SSB MV)
I also like to replace/add some workouts in weekends to accommodate 3-4 hour rides to build endurance base, just hours in the saddle.
Any tips advice?
