Insanity Fab Winter Challenge OPEN REGISTRATION STARTS
Wednesday oct 1st at noon
Same as years past, send a message to this page with vehicle info, pic , tee shirt size for you and codawg , class you wish to enter.
Below are the list of classes.
Racing will start on the morning of Thursday January 8th for SXS, Small and Big Tire Classes and race through Friday January 9th. If we run out of daylight on Friday we will finish the remaining races Saturday morning (no racing at night). Saturday January 10th the Unlimited Class will start their races. Depending on the amount of entries for Unlimited, we might run into Sunday January 11th for that class. The plan is to race normal classes the first two days then unlimited after , this is due to the course flagging change for the big boys.
We would like for racers in the first 3 classes to be at Nimac by Wednesday night for tech or before 8:00am on Thursday. For all unlimited racers you do not have to be there until Friday for tech.
We will be giving out a cash purse (amount determined by entries) for this challenge plus prizes and trophies.
