My last-years resolution was to quit smoking. Having succeeded, and being able to breathe again, , this years, is to lose weight and get into better shape. I dusted off the old Trek, and want to start riding. I know I shouldn't overdo it though. (I'm 50 btw, but had a stress test and the doctor says my ticker is fine.)

So, is there a web site somewhere that explains how to get started cycling? How much, how long, etc.

Also, is there a handy glossary somewhere? For instance, I just read a thread here talking about changing 46's for 52's or somesuch. I believe they were talking about gears, but thats all I know.

Is there somewhere I can bone-up on all the terminology?

BTW - if anyone feels real talkative, feel free to enlighten me right here.

Thanks all;
Artie
