Worst crash I had on the road was in the howling rain, I was racing to get home on my dirt jump bike, turned in hard into my road and the front washed out, and I slid across the road and hit the curb. I was wearing a t-shirt and shorts and got pretty cut up, and I took a huge chunk of flesh out of my knee, and it got infected.
Worst crash I had off road was at Chicksands on the 4 cross track. I jumped a big jump, overshot it and landed on the berm (with the bike vertical) slid straight off and round the berm on my side. Was wearing shorts and a vest this time so lost quite a lot of skin haha.
