Mike is pretty much right.
I ran the scoring (such as it was) at last years event, and it was a charity event with a very steep entry. The idea was to get corporations/local businesses to put up the entries for their employees or others.
There was also a celebrity race. two people I recall were Peter Boyles and Idel Arikawa.
The track was kinda short, but it was a fun track to run.
There is a similar event planned for this year, but what form and location it will take is uncertain right now.
