I have completed the 2x build phase programmes and I’ve started the Sustained Power build low volume programme. The low volume programme gives me 3x workouts in a week, then normally I go out for 2-3 days a week in addition to this, with nothing more specific in mind other than enjoyment. The weather is really bad here right now so I’ll be stuck indoors for the next few days on the trainer.
My question is what would be the best sort of workout to do on these days when I can’t just get out and ride? Sweetspot? Threshold? I’d be looking at a 2 hour workout on those staying in days.
