Been getting a lot of wonderful info out of these forums and thought I'd say hello/share my experience with my new hobby so far.
2 years ago I was pretty fit, 180lbs, running half marathons. Then I fishined a PhD dissertation, moved cities (and country) twice, wife got pregnant and I gained 60lbs. Last chrismas I saw a picture of me with my newborn son and thought "man I got fat!" I topped the scales at 240 and I was climbing fast, it was time to get back to my old self. I joined a gym, fixed my diet (mostly) and lost 20 lbs in a blink. But then I plateaued, lost motivation and started gaining weight again. I needed to shake things up, but didn't know how. Well luckily I live about 100 meters from a wonderful bike path "la route verte" http://www.routeverte.com/rv/index.php?page=home and I decided to take advantage of it. I went to my LBS and got myself a http://www.norco.com/news/wp-content...ing-Active.jpg which feels like riding a cloud and started riding. So far I've put almost 250km on it in about 6 weeks and I don't think I ever had this much fun being outside. I've defeated my plateau and weight creep and I'm down 8lbs since I got it.
Over the last 6 weeks I have:
Discovered a completely different perspective on my city
Found out how awesome padded shorts are
made appreciable C/V gains
Biked a marathon! (I'm really proud of that milestone)
Forgotten to unclip and fallen over a few times
