I want to Lose Weight the easy way

Cycling to work this week, 3 miles to the station then 3 miles through London. Unfortunately SPD's are not London friendly and with the amount of Traffic and Traffic lights it's rather a nuisance to keep unclipping and clipping back in in time to stop. A big thankyou to the Japanese tourist today who stopped to help me when my SPD failed to declip at the lights, resulting in me kissing the kirb. Although posing next to me for pictures taken by the rest of the coachload of tourists was a bit much. Perhaps I should have charged commision fee like Brad Pitt.
