I'll bite too:
My name is Ted. I'm 42 -- today.
During grad school on I started mountain biking a lot and did well loosing weight. Got older, quit smoking, moved to NYC, etc. Put on weight. Decided I had to do something about it so I bought a road frame (GT Edge) and some parts and built my road bike. I started having kids before I could start riding though so the bike sat unused for a few years. Started riding seriously last year. (I put more miles on my bike last year than my car.)
Now I ride to work most days and my goal is ten centuries this year and 2,428 miles.
