I'm 39 and recently got back into cycling -- I cycled everywhere as a kid, and even to work when I lived in Berkeley and worked in Oakland, but sold my bike when I moved east and have been out of the loop for about 15 years. I got back into it largely for fitness -- I've loaded on a lot of weight in the past 3 years after breaking my hip and biking is working well for me.
I currently own a well-used 2001 Caribou (Devinci) touring bike, which I love. (My 2nd purchase)
I also own a new 2007 KHS Alite 300 mountain bike which is a poor fit and so I'm trying to unload it. (My 1st purchase)
I'm a fulltime student (biotechnology at Seneca) in Toronto, Ontario. I'm trying to get to a century+ in one-day, and would love to actually do some touring next year. (Yesterday I did 65 km in 2.5 hours, so I'm getting there). It's great to be back in the saddle again!
