I spent an hour or so in the park, riding round in circles as sloooowly as possible on grass, practicing clipping out just before I toppled over. I've never had a clipless moment ... yet.
When I rejoined the world of cycling three years ago (proper MAMIL, me), still riding with toeclips, the most striking thing was how fast everyone else got going. My starting procedure would be: Check right foot tight. Start. Flick, miss, swear, (repeat) flick, catch. Left foot now in. Couple of pedal strokes. Reach down and tighten left. By which time my riding companions were down the road. Now the whole thing is replaced with "Start. Click".
