Just signed up to this site, I'm a reformed runner, after to many years to count, too hard on the body. I ride as much as I can, 100mi/wk, usually alone, (not a lot of people up here), in the Sierra Nevada mountains, beautiful country, but the hills are painful and long. Bike is a Specialized Neon hybrid, love the bike and I need the gears to get up and down them **** hills. Avid (wife thinks rabid) cycling fan, even when I was running. I'm a Dentist by profession, so if you have questions, let me know, and no I don't make house calls;-). If you use gels for energy, I REALLY need to talk to you.
