Attention amateur riders:  The amateur event is May 16th, and there will be no registration on Friday morning.  Due to the number of riders there will only be pre-registration, or late signup Thursday evening from 5:00PM to 8:00PM (late fee applies).

Riders meeting will be at 7:30AM - racing starts at 8:00AM.

In the event that your class isn't run on Friday, it will be run Saturday after pro qualification.  If for any reason your class isn't run at all we will refund those entry fees.

Note that there will be ATV classes!  They'll be run on their own hill, and there will be points kept for those classes in the Northwest Hillclimb Series (X-12, NWNN, and the Big Nasty).

There's also going to be a King of the Hill Klim!  To find out at the event!

Because of the increasing amount of nitro bikes we are going to have a Hot Pits wristband in 2014.  Anyone that wants to assist a rider in the staging area must buy a Hot Pits wristband and sign a waiver.  This is the staging and starting area.

No spectators allowed in this area.  This is a NAHA rule.

Hot Pits wristband is $5.00 per person, and we will be enforcing it. 


NAHA membership is required to compete in the pro classes
