I have a couple a couple of questions …
… to put everything in context I have been using trainer road for around 1yr or so. I am currently doing the general build - mid volume. My FTP is around 305w and max power is around 1000w.
Currently I am reasonable fit and feel I can plod along at around 290w for an hour or so. However if I do over threshold efforts I find I quickly fatigue. This is particularly noticeable in crit zwift race or in club rides when there are 1min over threshold efforts on a climb and struggle to keep it above 375w and then feel exhausted when I then go back into sub threshold. It feels like everyone else I am racing can “comfortable” increase power to 500w and then have quick recovery. Over an hours race these efforts are cumulative and struggle to keep steady state just below threshold (at the end of the race). The lack of power on the climbs and poor recovery is frustrating (and losing be positions in the race). However I know that if I am fresh I can easily keep 1min at 500w and have a max 5s power of 1000w. What am I doing wrong in the program or what sort of program would the forum suggest to increase power in over threshold effort with the ability to quickly recover.
On a unrelated note when I have 2hr of Z2 training do you get the same benefits of splitting the session into 2x1hr blocks rather than 1x2hr block?
any advice and insights would be great
