My Zwift addiction, as reported back in July '20, has resulted in me doing more virtual km than real life. I managed a year's total (my highest ever) of 9850km of which Zwift accounted for 5869km. So far this year I've done ~750km Zwift and zero real life...
I did a few Audaxes and got a mixed bag of comments from fellow members on here but if I hadn't have done the virtual rides I wouldn't have ridden at all so, for me, that's still better than nothing even if it's not real.
I've also pretty much stopped doing Winter MTB and have gone totally soft. The thought of getting crapped up (me, the bike and the washing machine) by riding through floods and mud then having to spend an hour or so cleaning said bike means the incentive to ride is diminishing, sadly.
That said, I am looking forward to doing group rides with real people again, one day...
