well, first off welcome and congrats on the weight loss so far.
As far as how fast you're riding compared to others, at this point, that's not as important for you. What's important is that you're progressing, be it in average speed, distance covered or days ridden. 150 miles in June is fantastic, given your relative newness to this. You should try to extend your longest distance when you can and when you feel ready to ... generally speaking a 10 percent increase is a good measure, so from 14 miles to 15 and a half or even 16, and so on. If you feel like you can do 20 percent, go for it.
And if you can cover those miles faster than you have in the past, even better.
It's really a matter of comparing yourself at this time, to where you were a week ago, or so ... keep at it, and you'll see improvement.
