Perhaps I was too terse.
Years of mountain biking causes a reflex where you protect your face from impact with your forearm, instead of a hand or foot. I believe martial arts teaches something similar. I have distinct memories of pulling back my hand in mid-flight, sacrificing forearm skin to not be in a wrist cast for 6 months again. The takeaway is, falling involves conscious thought.
Nerve: How did you crash? A worn cleat didn't release? Did you stick out the foot on the low side of the camber, instead of the high side? My point was, once it's clear in your mind what went wrong, you'll be very careful about that in the future. No more reason to stress over it, because you're consciously avoiding making the same mistake.
It happened as I was coasting in to a t junction. I was about to set off without unclipping but heard a car and I guess I panicked and failed to clip out.
I seemed to land with the minimal of force but unfortunately the wrong technique.
I'm pretty sure I unclip at the bottom of the pedal stroke, which I'm to believe is wrong. So first thing I must do is re learn my bad habit!
