Yes, Twice a year. Once you get booked into a class they send you the info on what day time etc. I went in april that year on a sweet saturday morning. They split the class into 2 groups, The fastest man/women out of each group wins the prize.
I got lucky enough to tie for first with the other groups fast man. We got to go back out for 10 more, The instructors in the last 10 laps really let it all hang out for us.
Its one of those things, Later in the day you pinch yourself because your still nervious. I took a few of my racing pals and a video cam with me.
