Pick a plan like the sweet spot base and go for it.
You don’t need the Sufferfest films, although they are good, the majority of my training is done watching the weekend’s CX via Sporza, or re-runs of old UCI world cup XC races on YouTube.
If you’ve got all the stuff then its a no brainer to give it a go, especially as you can cancel your subs, (and re-start them again), very easily.
