You might find day 3 worse!
15 minutes tempo,
1m 150%,
1m 50%
30s 170%
30s 50%
15s 200%
45s 50%
10s 200%.X 2.
I guess a kind of race finish simulation?
I quite enjoy this kind of effort personally.
Acliff-
Yeah, I'd already seen that. The 4x10s @ 175% on day 1 seemed relatively fine, so I've no idea how 200% would feel over that sort of duration.
Checked my power curve on Strava and that has 1 min at 135%. Definitely seems low (and I was certainly trying), but it was set on the short climb towards the end of Zwift's Innsbruck after busting a lung for 20 something mins up the main one.
Gonna knock 15% off my FTP and try day 2 again this evening. That should be about 150% for the 45s efforts.

Does anyone else have real problems with intervals at their supposed FTP? I know they're not supposed to be easy but I'm finding them impossible.
Day 2 of Zwift's 4wk FTP booster includes 6x 45sec @ 175% (at 5 minute intervals). First one I can just about manage, second my legs give up shortly before the end, and the third I've abandoned by 30 seconds in.
Don't think it's a case of the FTP being set unrealistically. Haven't done a specific test but have literally averaged it over an hour (also tallies pretty closely when extrapolated from my 20min averages). Whether it's accurate is irrelevant if it's the same equipment being used.
Feels like a physiological thing where I'm not just suited to these sort of efforts, at least not currently. Dunno whether to persist with this one until my legs HTFU, or reduce the target so I can at least get through it. The latter feels like cheating.
