As others have said, its the internet, there is going to be a certain amount of BS. That being said, you could do a Century if you've really ridden that much this year, you just haven't tried. I'm a clydesdale and 1 year after I started riding, I did my longest ride, which was 50-60 miles (New York Five Borough) at an average speed of 12 mph. I'm slow. I'm always going to be slow. I'll never been one of these guys like on the bike trails in full kit who pass me like I'm standing still but that doesn't mean I couldn't ride a century if I prepped for it. Given your 2000 miles this year, your light years ahead of me.
