Just did my first WORCS race ever, the Lake Havasu round (aka the gnarliest of them all, according to everyone I've spoken too).
Havasu was like 85% offroad, rest was MX... a horrible attempt at MX btw. Basically, it just had a few half assed man made jumps in one area, the rest was never ending sand whoops and rocks. I grew up and lived in Havasu for 17 years so it was actually fun for me.
Big bike classes are 55minutes plus a lap, pros are 2hours. Practice is Friday, most classes are Saturday, some classes and the Pros are Sunday.
I actually really enjoyed it. I got a flat front tire 20minutes into the race but up until then the weekend was great. Expensive as hell though, $25 to bring your vehicle into the facility, $25 a person to get into the gate, $45 or something per class, $40 membership and $40 transponder. You can do a one day membership and rent a transponder but I don't know what that costs, just go to their website.
Welcome to WORCS - World Off Road Championship Series : .
There's races at Hangtown, Hollister, Taft and Honey Lake this year... no reason not to atleast try ONE.
I can't remember offhand which ones I will and won't be at, depending on if I'm stuck at a Lorreta Qualifier, I know I'm missing atleast one of the above listed.
