Congrats on hitting that 25,000 mile mark and the weight loss. It's great to achieve something like this at an age where most people think we should be taking it easy.

I got my first bike in October of 2009 as a 63rd birthday present from my wife. I didn't really start to ride until spring of 2010. I haven't quite reached your status, but I've lost 35 pounds and I'm very close to 15,000 overall miles. I only started keeping track of my mileage when I got my hybrid in July of 2010, so I don't know how many miles I put on the bike that my wife gave me.
