It can be depressing sometimes how much harder it is to ride 23mph versus say 20 mph. The air resistance increases exponentially and it's like trying to swing a trash can underwater. I mention this because I did my commuting intervals today. Normally the intervals of harder riding are for only a minute. Today I tried to go about 2 minutes a couple of times in more traffic friendly spots.

Of course it was exhausting. There are all kinds of crazy obstacles, other cyclists, cars pulling out into the cross walks, last minute light changes. So it's not the most scientific way to train.

Got a Fed Ex confirmation that my new wool jersey is soon to arrive just in time for colder weather.
