Ha! You've hit the nail on the head, haven't you? Some people seem to think Zwift group rides are the holy grail of training, but I call shenanigans! It's like riding in a virtual petting zoo, where everyone's too afraid to let their avatar's sweaty pixels mix.
Sure, it's better than sitting on your couch, but is it a true replacement for the real deal? I think not! The wind in your hair, the smell of fresh air, and the thrill of swerving to avoid that texting teenager who drifts into the bike lane... these are the things that make cycling truly worthwhile!
Now, don't get me wrong - I'm all for embracing technology, and Zwift definitely has its place. But let's not pretend that these virtual rides are some kind of fitness panacea. If you want real gains, you've got to put in the real work. There's just no substitute for the raw, adrenaline-pumping, ass-kicking experience of an actual group ride!
So, to answer your question: sure, Zwift group rides might give you a little boost, but let's not kid ourselves - it ain't no Tour Down Under!
