I've smacked the pavement a number of times over the years and each time it's my palm, wrist, forearm, elbow and shoulder that takes the brunt of the impact. I have the scars to prove it. Usually it's on my left side from trying to protect the drive side of my bike as I'm hurtling toward the ground.
My collar bone was wondering "is that all you got? Meh. Piece of cake." Got the bike fixed up enough and rode it back home. I was stiff and sore the next day but no real harm done. Except for the cracked open helmet and a few items of kit. Oh and the abuse to the bike. It made me thankful that I'm not a "real" cyclist. It gave me some consolation for always being the last guy up the hill and for being the big guy that's usually popping off the back. It made me glad (kind of) that you don't have to squint to see my upper body like you have to do with a "real" cyclist.
So, if you're a "real" cyclist, let ME inspire YOU. Do some upper body work. Eat something. Stat. I need you to slow down a little so I can keep up. I need you to get to a point where I can make it up the hill with you.
I learned a valuable lesson that day. Maybe I can share it with you "real" cyclists. The only thing that should be cracking is your helmet or your bike. Lift some weights. Please. Eat some food. Please. I'm getting tired of hearing your collar bones snap.
