Pasir Ris, 67 km. Someone arranges a cycling session for those who can't cycle. I turn up to help. Most of the thirty who show up have cycled before, a long time ago, or just a handful of times. And some had bad experiences. Perhaps it's coincidence, but cycling is a little like flying. After all, the Wright Brothers had their start in bicycling before flying. Take off and landing are important, cruising is the easier part. With pedal in position, push off and keep pedaling. Keep above stalling speed to cruise, power through turbulence such as uneven ground, keep on the "flight path" to steer clear of other traffic. Slow down and brake to a stop before jumping out of the cockpit. It takes more guts to jump off a moving bike! One "student" starts by scooting on the ground, by the end of two hours, she's cycled on grass, up a small kerb (by accident) and powers her way back on track. She even navigates through a mixed crowd of kids and other cyclists :o
Meanwhile, I have a crick in my neck. But my crank is silent. After a certain bikeshop had wanted to charge me $55 to locate and silence the creak, I went to DIY. After some km of experiments (eg creak when I push down with the right foot, but not with the left, nor when I coast), it turns out a chainring bolt is loose.
