Great weather (18C and sunny), my first commute of this year with only a t-shirt and shorts, the rest have been between -6C and 9C so a nice jump in temp.
A great 28km though I forgot my watch and really don't know how long I took, I don't really care it was just that nice!
I did forget to bring a change of shirt to the office though, so had to quickly dash out to wally-mart nearby for a new one...
