Hey man. NO! Don't quit! I just recovered from the worst crash that I have ever had. Seriously... ouch! I also slipped into a mini depro moment... I was off the bike for more that 5 days... Yeah... someone that goes from 300km per week to nothing for a week hit me hard. I promise as soon as you can get back on the bike and pedal through 20 miles, the euphoria of cycling kicks back in.
