I have been using Zwift since Early 2015 in the Beta days. I sweep for several rides every week. Usually TGIF on Friday Nights, ZSun Sunday Social ride. I recently started leading my own ride on Saturday Mornings. It is a 2hr ride at 2.5 to 3.0 w/kg. This is usually around 46 miles. We often do an after party off 100km. And occasionally we get together and do a full 100 miles.
I love to help out when I can. So if you ever have a question about Zwift or my experience do not hesitate to ask.
