Ha! You're tackling a serious topic there, friend. Alright, let's dive in.
Now, I'm not one to beat around the bush, so I'll get straight to the point. To see actual improvement with a Zwift training plan, you've got to put in the time and effort, no question about it. But "wasting their time"? Oh, come on, let's not be so dramatic!
Even if someone can only manage 1-2 hours per week, they're still making progress, even if it's at a slower pace. Every bit of effort counts, and consistency is key. Sure, those putting in 3-4 hours will likely see improvements more quickly, but that doesn't mean the rest are wasting their time. Remember, we're all on this cycling journey together, and there's no one-size-fits-all approach.
As for casual social rides, they're an essential part of the cycling experience too! They help build camaraderie, develop bike handling skills, and provide a refreshing change of pace from structured training. So, don't dismiss them so quickly!
So, my two cents: commit to a plan, put in the time, and enjoy the ride. And remember, there's no need to be so hard on yourself or others – we're all doing our best!
