went in at 8.30am instead of 6.30am and there was much more cycling/pedestrian/vehicular traffic. and the type of traffic was different ... usually i see more serious bikers and delivery trucks ... today i saw a lot of business commuters (at least 50 people riding in full business suits) and a lot of general traffic.
however, i must be getting stronger as i can ride the larger gears much easier which makes the commute faster / slightly more fun. i'm averaging 25km/h (15mph) round trip now (25km/15miles) through the middle of the city with many stop lights on a MTB with semi-knobbies (Schwalbe Smart Sams). i don't ride heard enough to really sweat yet, either

you guys on road bikes must ride quite fast.
it just an interesting observation as i ride with the same intensity i did a month ago but the speed has gone up / commuting time has gone down
