Zwift's Virtual Tour de France Broadcast

This isn't overly technical, but it's a good look behind the scenes at how the virtual race is being produced in real-time.

TL;DR: just like everybody else, they use Zoom (and then some...)

But what I find more striking is how a tech company in the fitness industry really hit the big time and because of the virus, has expanded their platform from amateurs cycling/training at home, to running a top pro cycling event. Apparently, it's "only" a 6-stage demonstration of the technology, to fill the media void over the summer when it usually runs. The real race is still planned for the fall.
