"Nobody Will Ever Reach the Top": Conquering Colorado's American Mountain by Road Bike at the Century-Old Racing Mecca of Pikes Peak

In 1806, explorer Zebulon Pike stood in the distance and gazed at this peak, declaring that it would “never be climbed by human beings.” More than two hundred years later, you can drive up it, take a train up it, or even—if your legs are strong enough and your lungs are up to the task—pedal a road bike all the way to the summit of this 4,300-meter-plus “America’s Mountain.” Pikes Peak is not only one of Colorado’s most iconic landmarks; it also boasts one of the most legendary hill climb courses in global motorsport history, along with a chapter of cycling challenges that enthusiasts have only begun to explore in recent years.

Route Basic Information Table

Pikes Peak is the most famous “ultra-prominent fourteener” in the Front Range of the Rocky Mountains—meaning a peak exceeding 14,000 feet in elevation with significant topographic prominence relative to its surroundings. This terrain characteristic makes it strikingly visible from the direction of Colorado Springs, and it is also why the mountain has been a major landmark of American Western frontier culture since the 19th century—the slogan “Pikes Peak or Bust,” a famous motto of pioneers during Colorado’s gold rush era, reflects the mountain’s symbolic status in the history of the American West.

Beyond its topographic prominence, the mountain’s nickname “America’s Mountain” also stems from another contribution to American cultural history: in 1893, a writer who summited the peak was so moved by the sweeping vista that she penned a poem that was later set to music and became one of America’s most beloved patriotic songs. This legacy makes Pikes Peak more than just a mountain in the American psyche—it carries deep cultural and emotional resonance, which is why, even though Colorado has other higher peaks, Pikes Peak remains one of the most famous mountain landmarks in the entire country.

Imagine Zebulon Pike’s declaration that “no human will ever climb to the top,” and contrast it with today’s scene of tens of thousands of tourists, racers, and cycling enthusiasts taking on the mountain every year. This historical irony is itself part of the narrative appeal of this route—it reminds every challenger that humanity’s definition of “impossible” is constantly being rewritten by time and willpower.

Pikes Peak International Hill Climb: A Legendary Course in Motorsport History

Before discussing the cycling challenge, you must first understand the reason this road truly became famous—the Pikes Peak International Hill Climb, a hill climb motorsport event held since 1916 with a history spanning over a century, long regarded as one of the most iconic hill climb races in the world, nicknamed the “Race to the Clouds.” This event has given the Pikes Peak Highway toll road a unique place in motorsport and automotive industry history, with major manufacturers and drivers long treating record-setting runs here as the highest honor. It is precisely because of this deep racing heritage that the road’s pavement quality, corner design, and safety barriers are maintained to a higher standard than many purely tourist-oriented mountain roads—which, to a certain extent, is a bonus for cyclists: the road surface is generally in good condition, and corner sightlines are designed with high-speed dynamic passage in mind.

In recent years, cycling has gradually carved out its own stage on this legendary road. The Pikes Peak Cycling Hill Climb has been held since 2010, and the USA Cycling National Hill Climb Championship has chosen this venue since 2016, making this mountain—famous for motorsport—simultaneously one of the key goals for American road cycling hill climb enthusiasts.

This phenomenon of “motorsport and cycling sharing the same legendary road” is rare worldwide. Most hill climb courses famous for racing have road surfaces and safety standards optimized for high-speed motorized vehicles, which are not necessarily suited to the prolonged exposure of a human-powered bicycle climbing slowly. But because the Pikes Peak Highway also serves general tourist vehicle traffic, and the road management authority has actively maintained pavement quality in recent years, it has unexpectedly become one of the few exceptions that combines racing pedigree with cycling friendliness. For riders who follow both motorsport culture and cycling, being able to experience the historical weight of a century-old course while measuring the hardship of altitude gain with their own legs on the same road is a uniquely dual appeal of this route.

Segment-by-Segment Breakdown

From the Cascade Toll Gate to the summit, public sources often mention a series of continuous hairpin switchbacks in the upper section of the Pikes Peak Highway known as “The W’s”—one of the most visually striking and technically demanding stretches on the entire road. Overall, the route is broken down here into three segments based on start/end points and terrain characteristics; actual gradient changes should be confirmed with on-site signage and mile markers.

First Segment (Cascade to Mid-Elevation Forest Zone): Starting from Cascade near Ute Pass, the initial section winds through dense pine forests. The starting elevation itself is already above 2,500 meters, far higher than the starting points of most mid-elevation climbs familiar to riders in Taiwan. This section has a moderate gradient, serving as the process of your body gradually adapting to a sustained climbing rhythm—but remember, you are beginning this challenge from an already considerable elevation base.

Middle Segment (Forest Zone to Treeline, Continuous Hairpin Zone): This is the area where the “The W’s” hairpin switchbacks are located. The continuous zigzag corners demand constant adjustments to body position and pedaling rhythm, making bike-handling skill just as important as fitness. As elevation continues to rise, trees gradually thin out, and the views on this section progressively open up, offering sweeping vistas of Colorado Springs and the surrounding plains.

Final Segment (Above Treeline to Summit): After leaving the treeline, the route enters fully exposed alpine tundra terrain. Elevation here approaches or even exceeds 4,000 meters, and the limiting effect of thin air on power output is most pronounced in this section. The summit weather is known for its “polar climate,” and public sources indicate that afternoon thunderstorms with strong gusts are common in summer—a critical factor to account for in safety planning. Upon reaching the summit, you will find a visitor center and related facilities built to commemorate the mountain, a ceremonial photo spot for many who complete the ride.

Pacing Strategy: The Altitude Challenge Begins at the Start

The pacing plan for the Pikes Peak route has a distinctive feature compared to other high-altitude climbs—because the starting point (Cascade) is already above 2,500 meters in elevation, you are in relatively thin air from the moment you turn the pedals for the first time, with little room for a “low-altitude warm-up.” The implication for pacing strategy is: do not treat the early section as a casual warm-up segment. Instead, you need to start from the very beginning with a relatively conservative, sustainable intensity, because your body has almost no opportunity to fully warm up at lower altitudes before entering high-altitude challenge mode.

When you reach the middle section’s “The W’s” series of switchbacks, the concentration required for bike handling will divert some attention away from monitoring your physical output. At this point, it becomes even more critical to rely on pre-set power or heart rate zones to automatically regulate your effort, rather than judging by feel. In the later section above the treeline, the oxygen intake limitations from altitude become increasingly pronounced, and your perceived exertion is likely to read artificially high. It is recommended to shift your goal to “maintaining a steady, sustainable minimum effective output” rather than chasing speed, distributing your limited energy and willpower evenly across this final, most demanding stretch—avoiding the temptation to surge too early just because the summit buildings are in sight, which could leave you exhausted and pushing your bike at the end.

The Impact of High Altitude on Power Output: Living with 4,300 Meters

Pikes Peak’s summit sits at approximately 4,302 meters, similar to Mount Blue Sky, another route featured in this series—both qualify as “near-4,000-meter-class” road cycling finishes. This means this route likewise demands serious attention to the limitations high altitude imposes on the body’s oxygen uptake and sustainable power output. The route’s average elevation is around 3,400 meters, where the calculated air density is only about 60% of that at sea level. This reduction is significant enough that, at the same perceived exertion, your actual power output will be noticeably lower than at sea level.

It is worth noting that while Pikes Peak and Mount Blue Sky have similar summit elevations, their climbing profiles differ slightly: Pikes Peak starts from Cascade at over 2,500 meters, meaning riders are immediately operating in a mid-to-high altitude environment from the start, without the longer low-altitude warm-up sections found on other routes. This means the body must contend with altitude-related oxygen limitations from the very first pedal stroke, making pre-race altitude acclimatization planning even more crucial.

Power and Pacing Estimates

P = (Fg + Fr + Fa) × v ÷ drivetrain efficiency
Fg = m × g × sin(arctan(grade))　　gravitational component
Fr = m × g × cos(arctan(grade)) × Crr　rolling resistance
Fa = 0.5 × ρ × CdA × v²　　aerodynamic drag

Parameter settings: rider weight 70 kg + bike and gear 9 kg, total 79 kg; g = 9.81 m/s²; Crr ≈ 0.005; CdA ≈ 0.32 m²; drivetrain efficiency ≈ 0.975. Calculated for the full distance of approximately 30.6 km with about 1,800 meters of total climbing (average grade ≈ 5.9%, average elevation ≈ 3,400 meters, air density ≈ 60% of sea level):

These are physical model estimates that do not account for wind, road surface, or body size differences, so actual results will vary. Following the same estimation logic as the aforementioned Mount Blue Sky, this table assumes the rider can sustain a constant power-to-weight ratio throughout the entire climb. However, in an environment between 3,000 and 4,300 meters, riders who are not acclimatized will typically sustain lower power output than at sea level. Therefore, the table figures should be viewed as theoretical lower bounds, with actual finish times generally being longer. As for the century-plus of records accumulated in the Pikes Peak International Hill Climb motorsport history, those involve motorized vehicles rather than human-powered bicycles—fundamentally different in nature, and this article will not conflate the two. Regarding bicycle race results (Pikes Peak Cycling Hill Climb, USA Cycling National Championships) from top riders over the years, times vary considerably across years and categories; interested readers are advised to consult the latest official race announcements for current information, as this article does not list any single record figure.

Equipment Recommendations

• Gear Ratio Setup: The overall average grade is about 5.8%—not as brutal as Mount Washington, also featured in this series—but given the fatigue-amplifying effects of altitude gain, it is still recommended to retain some low-gear flexibility in your setup. Especially on the continuous switchback sections where you need to frequently adjust your output rhythm, overly heavy gearing will make both bike handling and energy management more difficult.
• Insulation and Windproof Layers: The summit is an arctic-level environment; even on a summer attempt, temperatures and wind chill can be severe. Lightweight, packable insulation and windproof layers are essential—put them on promptly after reaching the summit to avoid prolonged exposure to the wind.
• Tire Pressure and Grip: The continuous switchbacks demand strong tire grip. It is recommended to use road tires with stable, reliable traction and adjust tire pressure appropriately based on road conditions to balance climbing efficiency with descending confidence.
• Braking System: For the long descent with continuous switchbacks, disc brake models generally perform better in terms of heat dissipation and braking precision. If using traditional rim brakes, pay special attention to the risk of rim overheating from prolonged braking.
• Nutrition Planning: Supply points along the toll road are limited. It is recommended to carry sufficient water and energy supplies for the entire ride rather than relying entirely on roadside facilities—especially above the treeline, where there is virtually no shelter or resupply opportunity.

A Taiwanese Cyclist’s Perspective

For Taiwanese cyclists, the most valuable aspect of Pikes Peak is how it demonstrates that a “motorsport mecca” and a “cycling mecca” can coexist and thrive on the same road—a situation Taiwan also has parallels to, where the roads around Wuling carry the cultural significance of being a pilgrimage site shared by cyclists, motorcyclists, and motorists alike. The difference lies in the fact that Pikes Peak Highway is a toll road with stricter management, where the rules for sharing the road between cyclists and motor vehicles are relatively clear, whereas most mountain roads in Taiwan are general open roads with different traffic management models. This is something to pay special attention to when planning your trip, as local regulations may vary.

Altitude acclimatization is equally a key preparation item for this route. The starting point at Cascade already exceeds 2,500 meters in elevation, comparable to the altitude range between Cingjing and Hehuan Mountain in Taiwan, while the summit at 4,302 meters is significantly higher than Wuling. It is recommended to spend several days acclimatizing in the Colorado Springs area (which itself sits at over 1,800 meters) before the attempt, rather than challenging it immediately upon arrival. If your usual training grounds are Taiwan’s high-altitude roads like Wuling or Hehuan Mountain, this experience—while unable to fully replicate the thin-air sensation at 4,000-meter elevations—can at least build a certain level of familiarity with high-altitude riding, helping to reduce both the physiological and psychological burden when taking on the real challenge.

It’s worth noting that the handling challenges of this route—the consecutive hairpin turns—bear some resemblance to sections of Taiwan’s Beiyi Highway or Southern Cross-Island Highway that local cyclists know well; all are technical climbs requiring constant weight shifts and precise cornering lines. The difference is that Pikes Peak’s hairpins occur at mid-to-high altitudes, where the handling burden and physical burden compound simultaneously—a combination rarely found on most of Taiwan’s technical climbing routes, which are typically at mid-to-low elevations. For Taiwanese cyclists planning to take on this route, in addition to muscular endurance training, it is advisable to specifically strengthen handling stability training under fatigue—for example, deliberately scheduling technical sections at the tail end of long climbing sessions to simulate the real scenario of maintaining precise control while energy levels are depleted.

In terms of itinerary planning, the Colorado Springs area offers numerous renowned outdoor attractions and hiking trails beyond Pikes Peak itself. Many cyclists traveling from Taiwan or other parts of Asia combine this challenge with sightseeing in the surrounding area, spending several days simultaneously acclimatizing to the altitude and scouting the route beforehand, rather than diving straight into the official attempt upon arrival. This rhythm of “familiarize first, then challenge” provides tangible benefits in reducing overall risk and increasing the likelihood of completing the ride, while also transforming the entire journey from a singular physical challenge into a more complete and memorable cycling travel experience.

Safety Reminders

• Afternoon Thunderstorm Risk: Summer thunderstorms in the Rocky Mountain region develop rapidly in the afternoon. Sections above the summit and treeline are fully exposed; if you notice rapidly changing weather, you should immediately consider descending to avoid exposure to lightning risk.
• Altitude Sickness Warning Signs: Symptoms such as headache, nausea, difficulty breathing, or confusion should prompt an immediate stop of ascent and, depending on the situation, descent to lower elevation for medical attention. Those with a history of cardiopulmonary disease should consult a physician for evaluation beforehand. The advice provided in this article cannot replace professional medical judgment.
• Consecutive Hairpin Handling: The “The W’s” section in the middle features dense switchbacks. When climbing, pay attention to safe distances from oncoming traffic and overtaking vehicles; when descending, control your speed cautiously to avoid accidents caused by limited visibility around corners.
• UV Protection: Ultraviolet intensity at high altitudes is significantly stronger than at lower elevations. Prolonged exposure requires proper sun protection measures.
• Toll Road Traffic Regulations: Be sure to comply with local toll road regulations regarding cycling, including time restrictions and direction of travel. Always defer to the latest official announcements before your trip.
• Medical Emergency Checklist: If you experience severe chest tightness or pain, confusion, persistent vomiting, limb weakness or numbness, or slurred speech, stop activity immediately and seek medical attention. These may be warning signs of altitude sickness, cardiovascular, or neurological emergencies—do not push through the challenge. All training and safety advice in this article is for reference only; individual differences are significant, progression should be gradual, and this content cannot replace professional medical evaluation. Those with a history of cardiopulmonary disease, diabetes, or other chronic conditions must consult a physician beforehand to assess whether they are suitable for this type of high-altitude endurance activity.
• Sharing the Road with Motorized Vehicles: This is a toll road used by cars, motorcycles, and occasionally racing events. Cyclists should constantly monitor approaching traffic, especially on corner sections with limited visibility, and comply with local regulations regarding cycling direction and time windows. Rules may also differ between race days and non-race days.

Because this road simultaneously serves as both a motorsport mecca and a tourist attraction, traffic volume can be considerable during certain seasons and times of day. It is recommended that challengers start during periods of lighter traffic (such as early morning on weekdays) and remain vigilant at all times to respond to unexpected situations—do not let a speed-seeking mindset compromise your judgment regarding riding safety. When lingering at the summit after finishing, also be aware that the body’s recovery rate may be slower at high altitudes. It is advisable to rest adequately, replenish fluids and calories before considering the descent, and avoid rushing downhill before the body has recovered simply to complete the itinerary within a limited timeframe—this is an aspect requiring particular caution on the consecutive hairpin sections.

Key Takeaways

• Pikes Peak Highway is approximately 31 kilometers long, climbing from the Cascade toll station to the summit at about 4,302 meters. It is one of the world’s most famous hill climb racing courses, having hosted the Pikes Peak International Hill Climb since 1916.
• In recent years, cycling hill climb events (Pikes Peak Cycling Hill Climb, USA Cycling National Championships) have also chosen this venue, making this “motorsport mecca” a significant challenge target for cycling enthusiasts as well.
• Physical model estimates suggest a 2.0 W/kg entry-level finisher would take approximately 3 hours 8 minutes, while a 5.0 W/kg professional-level rider would take about 1 hour 21 minutes; however, given the average elevation of approximately 3,400 meters and air density at only 60% of sea level, actual finishing times are generally longer than model figures.
• The starting elevation already exceeds 2,500 meters, leaving little room for low-altitude warm-up—altitude acclimatization planning is more critical here than on many other climbing routes.
• Afternoon thunderstorms and consecutive hairpin handling are the most important safety concerns on this route; be sure to check weather forecasts beforehand and control your speed cautiously.
• Since the starting elevation already exceeds 2,500 meters, pacing strategy cannot treat the early section as a casual warm-up; it is recommended to adopt a conservative, sustainable power output from the very start.
• It is recommended to spend several days acclimatizing in mid-to-high-altitude towns before the challenge, and to do additional training on handling stability under fatigue to meet the technical demands of the mid-section’s consecutive hairpins.
