Hi Dan, actually our sweet spot workouts are called sweet spot progressions and broken into two pieces main work and secondary work. We leave the main work exactly the same for indoor and outdoor the secondary work just has a intensity target and we mostly keep that intact for the simplified outdoor workouts. In the beginning of our plans especially if you start at level one, the main work is short and mild but as you will see later in the plan the main work can take 45 minutes or more in some cases. So our sweet spot are not like trainerroads at all. We are not doing long harder sweet spot durations at the beginning of the plan and even at the end they are “reasonably” longer efforts. But as Giancarlo pointed out for some users like him we made those last blocks too simple (meaning very long single focused efforts efforts).
Does this make sense? It’s not always obvious what is main work or secondary work until you start to understand our workouts. But in the beginning the main work can be like 10 minutes or less.
