WHAT ARE THE MOST ICONIC CLIMBS IN PROFESSIONAL CYCLING?
From the serpentine switchbacks of Alpe d’Huez to the wind-blasted slopes of Mont Ventoux, professional cycling’s most iconic climbs have defined careers and shaped grand tours. These legendary ascents are more than just brutal physical tests—they're historical battlegrounds where legends are forged. In this guide, we’ll explore what makes a climb truly iconic: its history, difficulty, atmosphere, and the unforgettable moments that have unfolded on its slopes. Whether you’re a cycling enthusiast or just discovering the sport, these legendary routes offer an awe-inspiring glimpse into the drama and glory of pro cycling.
Alpe d’Huez: switchbacks and legacy
The 21 bends that built a legend
Alpe d’Huez is arguably the most famous climb in all of professional cycling. Located in the French Alps and featuring 21 legendary switchbacks over 13.8 kilometers, this climb has been a defining feature of the Tour de France since its debut in 1952. With an average gradient of 8.1%, it’s not the steepest ascent, but the relentless rhythm and massive crowds create a gladiatorial arena that amplifies its difficulty and spectacle.
Eddy Merckx, Bernard Hinault, Marco Pantani—these names are etched into the tarmac of Alpe d’Huez. Pantani still holds the unofficial record for the fastest ascent, clocking in at 36 minutes and 50 seconds in 1997. Each bend is named after a past stage winner, making every switchback a nod to cycling history.
What elevates Alpe d’Huez beyond its stats is the sheer theater it provides. Fans camp out days in advance, transforming the climb into a chaotic tunnel of noise, flares, and flags. It's a bucket-list climb for amateurs and a decisive battleground for pros. Riders don't just race up it—they make statements.

Mont Ventoux: the bald giant
A climb that takes your soul
Mont Ventoux, also known as “The Bald Mountain,” rises ominously from the Provence landscape. Its desolate, lunar summit at 1,909 meters makes it visually and physically unforgettable. Spanning 21.5 km at an average gradient of 7.5%, it’s notorious for its punishing exposure to the wind, which has reached gusts over 100 km/h during races.
But what truly cements Ventoux’s mythos is its dark history. In 1967, British cyclist Tom Simpson tragically died on its slopes during the Tour de France, a haunting reminder of the climb’s brutality. Riders today still pass a memorial in his honor, often tossing bottles or caps in tribute.
Physiologically, Ventoux is a monster. The initial forested section lulls riders into a rhythm before the final 6 kilometers expose them to the elements with no shade or reprieve. This transition is where races unravel, and where heroes are born—or broken.

Whether conquered in solitude or cheered by thousands, Mont Ventoux demands everything. It's not just a climb—it’s an experience of the soul.
Passo dello Stelvio: high and mighty
Italy’s Alpine epic
The Passo dello Stelvio is a crown jewel of Italian cycling, revered for its altitude, switchbacks, and cinematic vistas. At 2,758 meters, it's one of the highest paved passes in the Alps and a cornerstone of the Giro d’Italia. The climb from Prato allo Stelvio is 24.3 km long with a 7.4% average gradient and a jaw-dropping 48 hairpin bends.
Its epic scale and Alpine scenery make Stelvio as much a visual experience as a physical trial. Riders ascend into thinner air, testing their aerobic limits while navigating endless curves. The atmosphere here is more reverent than raucous—steeped in history, and often snow-capped even in late spring.
The Giro has repeatedly used Stelvio as a queen stage, most memorably in 2014 when weather chaos turned it into a near-mythical event. It’s a climb that demands respect, with technical descending, changing weather, and psychological strain all in play.
