I don't know, there's very little info at the moment.There was a short article about his revalidation, and that he hopes he can train outside 3-4 February. Reason they didn't train outside yet was because the shocks would have too much impact on his shoulder.
What I don't understand, but someone else here might know. Why doesn't he do proper long trainings indoor? Is that just not realistic? Sure it's probably extremely boring, but physically it should be possible?
I would assume there's still a lot of kine/physio work on the shoulder going on so maybe there's just not that much time to do long indoor rides. Or maybe it's still not physically possible/advisable to do long rides.
Also, I don't think he uploads every ride he does to Zwift.
We should know more by next week.
