Because it's actually pretty ridiculous and offensive. Yes, I've laughed at the sayings. I've even sent one to my sister because it was pretty funny. As a matter of fact - it was this one right here:
But you know what my problem is? When I see someone saying that, but then they post their finish times and they are what I would consider fairly speedy. I'm not a super fast runner but at the same time I also recognize that my fast is someone else's slow, and my slow is someone else's fast.
And that's it right there - we all run at different paces and our pace is just that...OURS. What I can run doesn't change what you can run and vice versa, right? I don't run "slow"...I run MY PACE. And honestly, it's still not slower than this:
So let's just stop doing that, okay? No need to make qualifications and dismissals. Just run your own pace, run your own race and enjoy doing it while you're at it.
