That was in May. Since then, I've made some minor tweaks to the bike and racked up (I think) over 900 miles. Amateur numbers, of course, but that includes a Diablo summit, and a 60 miler around Marin and Tiburon... rides I never thought I'd be capable of. I've been commuting to South SF over Geneva Blvd, I can finaly climb a hill in a gear other than "granny", and I've lost about 20 lbs. It's helped my jogs up Twin Peaks as well; same muscle group, I guess. I did that lap in 45 minutes yesterday.
Here are some pics from a lap around Paradise Loop in Tiburon. It's one of the most beautiful circuits in the Bay Area (according to those who've biked every popular route). One of these days, I'll take some shots from the GG Bridge.
I've found my new Summer hobby.
