There are faster racing series. There are louder racing series. There are racing series that are easier to spectate and be a fan of. But none are as free and loose in terms of "run what you've brung" than hillclimbs. They're the last bastion of true, honest-to-God engineering insanity left for the average driver and enthusiast. And it's been that way since their inception.
The most famous of these hillclimbs is Pikes Peak in Colorado, as the race up the mountain is nearly 13 miles long, and only ends at 14,000 feet above sea level. It tests drivers to the max, as there's almost no room for error, and the vehicles brought to the race, as the thin air and razor-thin margins between all right and a Flight-For-Life helicopter take no prisoners. Nor suffer any poor engineering.
