I’m adding specific threshold intervals to my block (instead of just riding hills @thrs)
Today I’ve started with 2x24min (I have a climb that length) @91%FTP - it felt just ok, almost too easy (comparing to 5x4-5min vo2max intervals with 18min TiZ. sometimes on weekends I do 60min climbs at ~90%FTP, so those intervals felt “easy”).
so I’m just thinking that maybe it should be a bit more demanding? like 4x20-25min @90%FTP ? or 2-3x20-25min 95%FTP ? what TiZ should I aim for ?
and of course later I can progress with a bit more time or a bit intensity.
What training were you doing last winter that had you at a higher ftp than now? If something has changed a lot between then and now I would look there first.
If you’re already happily knocking out an hour at 90% there’s little point in doing sweetspot intervals right now, I think.
I’d do threshold intervals at 5 watts below FTP. Progress time in zone and interval length. Once you can do (say) 2 × 30, have a couple of easy days, carb up, and then do a long-form test to get a new FTP/TTE.
You may need to find a longer climb or alternative route at some point.
Then you’re going to want an easy week before (probably) hitting VO2s.
