Science Powers Victory in the Tour de France

The Evolution of Cycling: From Doping to Data-Driven Excellence

For fans of the Tour de France, the term “extraterrestrial” carries a unique and often negative connotation. In 1999, the French sports newspaper L’Équipe used the phrase “On Another Planet” to describe Lance Armstrong, not as a compliment for his extraordinary performance but as an implication that he was cheating. At the time, the accusation was based on rumors, and it took over a decade before the U.S. Anti-Doping Agency officially declared Armstrong guilty of doping. His seven Tour de France titles were erased from the record, yet the idea of “extraterrestrial performances” has remained a topic of discussion in cycling.

In 2023, L’Équipe returned to the same metaphor with the headline “From Another Planet,” this time referring to Jonas Vingegaard, the Danish cyclist who won that year’s Tour. Similarly, earlier this year, the U.S. magazine Velo highlighted the “other worldly” performances of Tadej Pogačar, the Slovenian favorite for this year’s race. Despite the impressive language, there is no evidence suggesting that Vingegaard or Pogačar are using performance-enhancing drugs. Their dominance in the sport is all the more remarkable given this.

This year, Pogačar is in a league of his own. Earlier this week, he achieved his 100th career win and could potentially surpass his 2024 record of winning nearly half the races he entered. Alex Hutchinson, a columnist for Outside magazine, posed the question: “How is Tadej Pogačar better than rocket-fueled Lance Armstrong?” This query reflects a broader curiosity about the current state of the sport. By all available data, the current generation of cyclists is faster and more skilled than ever before, even when compared to the era of widespread doping.

The sport’s history with doping was once so pervasive that it extended beyond professional riders to amateur competitors like myself. We would shake our heads at the occasional athlete caught using illegal substances—just to win a small prize in a local park race. However, the past decade has seen a significant shift. What was once a cycle of corruption has now become a virtuous cycle of clean competition and improved performance.

A key turning point came in the 1990s with the abuse of erythropoietin (EPO), a drug that increases red-blood-cell production. This led to years of enhanced performances, fueled by sophisticated blood-doping schemes. Travis T. Tygart, CEO of the U.S. Anti-Doping Agency, played a crucial role in ending this era and setting the sport on a better path. He emphasized that clean athletes can now win, and that fans should trust in their abilities, even if they achieve feats never before seen.

Cycling has evolved into a highly quantifiable sport, with power meters providing real-time data on a rider's performance. This data allows cyclists to train, race, and even publish their results on platforms like Strava. For example, during a critical mountain stage in last year’s Tour, Pogačar sustained approximately 7 watts per kilogram for nearly 40 minutes, while his main rival, Vingegaard, managed around 7 watts per kilogram for 15 minutes. These figures highlight the incredible advancements in human performance.

The benchmark for success in cycling is a rider’s ability to maintain a high power-to-weight ratio. In the past, a figure of 5 watts per kilogram was considered competitive, but today’s top riders exceed this significantly. Pogačar’s performance dwarfs even the peak of Armstrong’s doping-era achievements, demonstrating the dramatic progress made in the sport.

Technological advancements have also played a major role in improving performance. Tools like VeloViewer allow riders to analyze course details before competing, while precise weather forecasting helps teams make strategic decisions. Equipment improvements, driven by the philosophy of “marginal gains,” have led to lighter bikes, more aerodynamic designs, and optimized gear.

Nutrition has also evolved, with riders now focusing on precise calorie intake and quality meals. Former pro cyclist George Hincapie noted the shift from traditional methods to highly calibrated nutrition plans. Chefs like Hannah Grant work closely with teams to provide tailored meals, ensuring that each rider receives the right nutrients for optimal performance.

Despite these advancements, concerns about doping still linger. While some practices like sodium-bicarbonate loading exist, they are far less prevalent than in the past. The cycling governing body has taken steps to ban dangerous methods, such as microdosing with carbon monoxide.

Ultimately, the current state of the Tour de France reflects a triumph of science and clean competition. Fans may miss the days of race craft and guile, but the sport has moved toward a new era of excellence. As Pogačar prepares to finish the race, it’s clear that no extraterrestrial is winning. If his performance approaches perfection, it’s a testament to the power of human potential and scientific advancement.
