i must say you are mighty lucky, sadly the same thing happened to me except i was in a small race a week before canadian nationals tri race. I had just began the bike portion and a old man tried to squeeze through the course cutting me off and caused me to fly over the windsheild, somehow i was lucky and god was on i side. I suffered to blown knees but after 4 years i have quit riding because i just am not able to but ya take what you can get. so hope for you to get better soon
