had several as a kid but they don't really count IMHO
I've been back cycling regularly as an adult for maybe 10 years now and had 4 proper offs in that time
Norwich 100 2013? - corner, gravel, velocity, fall, slide - no biggie
Nurburgring 2014 - just done the MTB course. got back to the hotel driveway. corner, gravel, fall, whacked my head and shoulder. Had to do the rad am ring on the Nordschliefe the next day with one arm pretty much. never got it checked but fairly sure i fractured my shoulder.
Late 2014 - chain snapped sprinting from some lights - don't remember a thing as I smashed my head on the ground and knocked myself clean out. Then took an ambulance to hospital. Needed a week off work and wasn't right for a couple of months.
This was the incident after which I started wearing a helmet every ride.
Last June - In the Lakes, left Bowness, climbed the Kirkstone pass, did all the hard work and got to the top ready to enjoy the descent down the other side. Just then it started raining a little. As i went over the top lost the back wheel in the damp and washed out. Garmin says i was doing 40mph at this point. Trashed my ankle, hip, elbow, shoulder, shoe, shorts, jacket, backpack, bar tape and even took a chunk out of a water bottle!
Normally when you have a crash you get time for one clear thought, this time it was "well at least i'm wearing my helmet this time" and sure enough i cracked my head on the road again.
Am I slightly clumsy - yes
Has it put me off - not at all!
