Status update nearly 2 months down the line.
Short version:
Holidays caused end of plan FF to go south, but adjusted numbers based on feel (FTP 9 W lower compared to mid-plan HM). Into last week of MAP block now, not sure if I should do FF
, HM
, or just start a new plan with manual adjustment of FTP and MAP 
Which plan? Not sure. Considering Mountain Fondo, All Purpose (again) or Time Trial, all high volume, 3:1 with strength, yoga and mental training. What would be the main differences between them?
Season goal: Have signed up for a tough race/sportive end of June: 430 km with 4600 m ascent. Will do a few other races as well leading up to it.
12 week plan and then a couple of buidling blocks, or the other way around? Not sure, and would appreciate input.
Long version:
Was supposed to do a FF on Jan 1st, however, as I was driving home from Christmas that day (9 hours drive), and had more or less 2 weeks off the bike it did not seem like an excellent idea to do FF, so I loaded the FF prep plan to do it a week later. But with those 2 weeks off the bike I do (in hindsight) believe I was not fully back to the same leves as before Christmas with just an easy prep week, thus the FF became an epic fail in terms of completion, but after the worst disappointment was over, I felt I still had some answers. My MAP did not seem far off the result from my previous Half Monty, whereas my FTP felt somewhat over-estimated. Adjusted my FTP accordingly (9 W lower to be specific) and started doing a MAP building block (3:1) as planned, now being in the final week of the plan. Still, to complete the January challenge, the last week has been quite a bit harder than according to the plan.
I do not really look forward to the prospect of a new FF shortly, or even a HM for that matter, but feel like a test is in order to update my numbers, or verify the feeling they haven’t really changed much. As the legs feel a bit dead right now, that could change with some rest.
Then the question is; what comes next? I am considering either the high volume 3:1 Mountain Fondo, All Purpose, or Time Trial (with strength, yoga and mental training). They all seem quite similar to me, it appears the main difference would be MF has somewhat more focus on long slow duration in the weekends (would appreciate some coach feedback on any/main differences of these plans).
Have signed up for a race/sportive in the end of June, 430 km long with 4600 m total ascent. Will do a few others (shorter) leading up to the event as well. Approx 21 weeks until the event, and not sure whether to do a couple more building blocks, then do a 12 week plan, or the other way around.
