Here’s video of one of the fastest runs from the 2011 version, with a slightly changed course. This guy is absolutely flying!

I saw the photos of the 2011 race but I guess I didn't scroll far enough down to catch that video.
I also wondered if the handle bars on those racing bikes are customized because there are some narrow areas they go through.
I also noticed the brakes on my mountain bike make the same noise as those bikes so I presume it is normal...
