batblog T minus not enough at all

40 minutes non-stop on the spinning bike at just over 80% max heart rate. Heart of a lion, me. Was quite comfortable, a little tired in the last 5 minutes. The mad Serb shook my hand in congratulations. Maybe my max heart rate is too low. It must be. It was too easy. Very loud heavy metal on the stereo helped considerably. Boredom factor low due to Milos leaping in every 5 minutes to check my heart rate.
