Col du Tourmalet, France
A Tour de France icon since 1910 and the most visited climb in race history, Col du Tourmalet crowns the Pyrenees' highest paved pass. The western approach spans 19km with 1,404m of elevation gain at a relentless 7.4% average gradient.
L’Alpe d’Huez, France
The Alpine counterpart to Tourmalet, this iconic 13.8km ascent features 21 hairpin turns that push even pros to their limits—a world away from flat urban rides.
El Camino de la Muerte, Bolivia
Known as the 'Death Road,' this thrilling mountain bike descent starts at 4,700m near La Paz and drops to 1,200m. Guided tours mitigate risks, as most incidents involve vehicles, not cyclists.

Ho Chi Minh City to Hanoi, Vietnam
Grasshopper Adventures (grasshopperadventures.com) offers this 16-day epic from the Mekong Delta's lush lowlands, through Dalat's mountains, and over Hai Van Pass. Short daily stages help, but tropical heat demands frequent support vehicle stops for hydration.
Passo di Gavia, Italy
A Giro d’Italia classic in the stunning Italian Alps, this 26km climb gains 2,621m. Often snowbound in winter, it can deliver fierce weather even in summer.
Manali to Leh, India
Red Spokes (www.redspokes.co.uk) guides this Himalayan beast through pine forests, dirt tracks, and switchbacks to Leh—exclusively for hardcore cyclists, with rest days included.
Lake Louise to Whistler, Canada
After conquering the Rockies, tackle the Coast Mountains on this week-long tour (www.rockymountaincycle.com): over 1,000km and 11,000m of climbing that tests body and mind.

Cape Epic, South Africa
This premier off-road stage race shifts routes annually but delivers eight days of rugged terrain. The 2014 edition (March 23-30) spanned 698km with 15,650m of climbs (www.cape-epic.com)—dwarfing many Tour stages.
Alto de L'Angliru, Spain
A Vuelta a España hallmark in Asturias, this 12.5km monster averages a brutal 10.13% gradient, rivaling the Grand Tours' fiercest tests.
Three Peaks Challenge, Australia
Victoria's annual 235km event in 13 hours assaults Tawonga Gap, Mount Hotham, and Falls Creek alongside pros (March 9, 2014; www.bicyclenetwork.com.au). Team up—solo attempts not advised.
