The NAHA is an organization of professional hillclimb competitors and events held primarily in the western United States.  Our events are generally held on rough terrain, ungroomed uphill courses, sometimes over a thousand feet long!  Our style of hillclimb differs from the typical style in the eastern United States, where the hills tend to be highly groomed, faster terrain.


Feel the earth-shaking thunder of 2,500cc Harley-Davidsons, the haunting wail of high-powered 2 strokes, and smell the nitro methane burned by furious four-cylinder Open Exhibition bikes!  Hillclimb is the oldest of all motorcycle sports- the original extreme sport.  Witness the timeless war of man and machine vs. seemingly impossible hills on battlefields that only exist in the North American Hillclimbers Association!
