Cycled to work again today. Avoided the so-called recommended cycle routes and just bombed down the main road. This was far faster.
On Tuesday it took me an ermbarassing 45 minutes in and 55 minutes home. Today it took just 35 minutes in (respectable) and 50 minutes home (not particularly fast).
In fact, at 35 minutes, cycling is the fastest method for me to get to work (vs. Car, Bus and Park+Ride).
