My Zwift ride is now down for extended maintenance as of yesterday so I have cancelled as per their instructions:
https://zwiftinsider.com/zwift-subscriptions/Reason: I shall be riding outdoors. I don't begrudge the increase but last summer I didn't cancel but hardly used Zwift.
When I resume I hope to have a trainer only bike based on an old steel frame with more modern components. Seems a waste using a fully equipped road bike for the job and maybe they'll have introduced virtual gears for the kickr 5 in a few months.
