I left my house 15 minutes late today so I was about 5-10 minutes too late to catch the first of two bus routes for my commute (not that I wanted to take the bus). By the time I got to the station where I catch my second bus, I was running only about 2-3 minutes late. The bus left the station and crossed over a bridge and I turned in just behind it. Then, when I got to the last stretch before I got to work, the same bus was following me up the road (that route only runs every 45 minutes).
What took me an hour and 15 minutes a few weeks ago when I wasn't feeling it only took 47 minutes today. Granted, part of that is due to lower amounts of traffic and a flatter-yet-longer route. But still, the Clyde wins.
Oh, and when I got off of the bike, I was in a fantastic mood.
Average speed is up from around 9 mi/hr to about 11.6 mi/hr. And that with a bit of a headwind for a significant part of the ride.
