Great thread. It's really interesting to read about other people's commutes. Mine is 11 miles and 40-45 minutes each way (22 miles round trip). I estimate about 400 feet of climbing total. It's mostly MUP with some neighborhood streets and city streets. I carry my office clothes, shoes, shaving kit, and laptop (and spare tire, pump, etc.). I use a Carradice Bike Bureau panner. My ride is a Surly Cross Check that I built up as a commuter (fenders, rack, lights). I shower and change at the gym across the street from my office (and park in the garage under the gym).
