If I have the ability to do 30, 40, 60 min SS intervals then I see no point in spending 2 hours on the trainer limiting myself to doing 10-20 min intervals with almost as much recovery, e.g. Hunter, Antelope, Tallac.
If TR’s own definition of ‘sweet spot’ is “specifically aimed at improving your ability to resist fatigue at reasonably high power outputs over substantial lengths of time”, then why not do actual substantial lengths of time. Giving me 15 minutes of recovery time on a 20 minute interval (or 5 on a 10!) is neither improving my “ability to resist fatigue” nor improving my “reasonably high power outputs over substantial lengths of time”.
The plan is 6-weeks between FTP tests so unless you manually do it, your power isn’t changing, but also neither is duration. If you’re doing a 120min workout it’s very possible to do 2x45min…unless you never want to experience riding for 45min without a break. There are plenty of SS workouts with intervals of substantial lengths of time which could be adapted to the SSBHV plan, or create your own.
Wow did I ever hijack my own thread!
Train for your race, just don’t do it on the course!
