I rang my bell pretty damn good yesterday at a CO hare scramble. First time I have ever been knocked out. It was actually kind of cool although I would not want to do it again. It was in the worst whoop section of the first lap right before the check station. Well at least I got 6 miles of riding in. I had tried to time the whoops, jumping two at a time, like I had done in the practice lap. But I had to take a different line from the one in the practice lap because the guy next to me took my line. Dumb mistake. Should have rolled them. Jumped way over the second one and planted the front wheel into the third. That is about all I remember. I don't actually remember hitting the ground. I "woke up" with a guy and a lady over me asking if I was OK? She said I was down for about 2 minutes. The funny thing is, I swear I had a full dream in that two minutes. I tried to roll over but couldn't at first. Then I stood up, felt a little woozy and looked for my bike. It was OK. A little tweaked in the bars but I got them back in line. My helmet was not cracked but had huge scuff marks on the back and side. The rode my bike back to the truck. walked to the ambulance and they checked me over. I had a real bad headache and my shoulder hurt quite a bit. I had to wait around a while then they looked me over again and felt good enough to release me. I was a little groggy but I could remember everything (except how I hit the ground), my BP was good and so were my pupils. After I got home, the stiffness started to set in. From my neck all they way to my butt. come the evening time I could not move my arm or cough or blow my nose. My entire rib cage is sore, I can't lift my right arm more than shoulder height and I have a good size bruise on my forehead that runs down my right temple area. No headaches though which is a good thing. I took a bath and went to the bed. My wife had to pull me out of the bed every time I had to use the bathroom. Didn't sleep much last night. Been in bed all day except to go to the Dr. He took some Xrays and they were all negative. He said I am going to be sore for about a week. Lots of Ibuprofen and heat. My first loss of conciousness as well as my first DNF. Hope they never happen again.
