This happend a while back, but wasn't to aware of the forum then but i'll tell you the tale.

Went for a day up at inners with my mate and we got there and pushed right up to the road gap to hit make or brake. As we got to the top i felt sick and dizzy. I said to my mate " ill go behind cos i'm feeling weird " So, off we go we go over the last double thing, just before you come out the tunnel onto the freeride and i just got a huge headrush, started breathing rlly heavily and slammed on the back brake and pretty much fainted. Next thing i knew i woke up ( like i would wake up from a sleep ), felt like id been out for ages but it was about 20 seconds, my mate had actually gone down the freeride park but luckily someone stopped to help me. I wasnt injured, just a really, really big fright. So i took a rest, my mate finnaly comes back up and i tell him the story. I decide to take the fireroad back down. I had a can of redbull and a sandwich and i felt fine afterwards but kept easy for the rest of the day. I still had it checked out, the doctor ( my dad ) said it was probarbly due to lack of sugar in the blood or something because i hadn't actually eaten any breakfast that morning. So everyone should be aware to eat something before you go riding as the turnout could have been alot worse, this ever happened to anyone before ?

yer mate, just a lack of sugar.
had a diabetic mate who fainted quite alot due to because he hadn't eaten enough.
i feel wierd sometimes when not eaten much, but nothing as bad as fainting.

:S You never told me this lol. Hope you were ok.

was ages ago raymond, when i 1st had the patriot. before i even talked to you really

I got a urine test some months back and the doc said "yep, its definetly urine..."   

Alwyas feel a bit brainfkd and vague after riding when its hot, but this is probably due to dehydration more than anything...
