Established in 1972, this climb ranks as the third oldest continuously running hill climb in the United States and attracts an impressive range of participants, from Olympians and Tour de France riders to weekend warriors celebrating Boise’s vibrant cycling culture.

The challenge covers 4,314 feet of elevation gain over 18.5 miles, starting from Greenwood’s Ski Haus. The route begins with a neutral roll-out north on Bogus Basin Road, escorted by Boise Police Department for safety. The rolling start kicks off at the intersection of Curling, leading riders through varied terrain to the finish at Pioneer Lodge Parking lot. The climb tests riders with consistent gradients and mountain scenery throughout the ascent.

As a partner event in the Gran Fondo National Series, the climb offers European-style race organization with electronic timing chips tracking progress throughout the course. Riders can compete in timed sections for age group awards while casual cyclists enjoy riding at their own pace. The event provides both individual and team participation options, with special prizes awarded across all age and gender categories.

The well-supported event includes parking at Harrison Hollow Trails and strategically placed restroom facilities. The organized start ensures smooth logistics for the field, while the mountain setting provides a scenic backdrop that veteran participants consistently praise. The combination of historical significance, quality organization, and the challenging but achievable gradient makes this climb a standout in the American hill climb calendar.
