Have been commuting for the last 3 years, but have just recently found this site, lovin' it.
Did a 20km loop this morning on the new bike (Scott, Sub 20 Classic), came home, and took the beater into work for another 10km. (Recently had a bike stolen, so the new bike isn't going to work) Nice ride, a bit humid. Ride home (10km) - headwind, hot and humid.
Little 'game' I play - for each rider I pass +1, if I get passed -1. Today's score: +4 (didn't get passed).
Going to add another 10km or so to the morning ride tomorrow morning.
