Steven de Jongh has emerged as the primary performance architect behind Mads Pedersen’s success in the Tour de France, utilizing a rigorous, data-driven training approach characterized by high volume and precision. According to reports from WielerFlits, de Jongh’s “workaholic” methodology focuses on optimizing Pedersen’s ability to withstand extreme conditions, including the high heat encountered during the race, to maintain peak competitive power.
The Performance Strategy of Steven de Jongh
Steven de Jongh operates as the technical lead for Mads Pedersen’s physical preparation. The partnership centers on a philosophy of relentless consistency. De Jongh is described by sources as a “workaholic,” a trait that reflects in the structured, high-intensity training blocks he designs for the Danish rider. This approach isn’t just about raw wattage; it is about the ability to repeat peak efforts over a three-week Grand Tour.

The core of de Jongh’s architecture involves a tight feedback loop between power data and physiological response. By monitoring Pedersen’s recovery and output, de Jongh adjusts training loads in real-time to ensure the rider hits the Tour de France in a state of “supercompensation”—where the body over-recovers from a hard training block to reach a higher level of performance than before.
Tackling the Heat of the Tour de France
One of the most critical components of the Pedersen-de Jongh partnership has been heat adaptation. De Volkskrant reported that while some critics questioned the decision to race in temperatures reaching 40 degrees Celsius (104 degrees Fahrenheit), Pedersen has managed to endure these conditions effectively.

Heat acclimation is a specific pillar of de Jongh’s program. This typically involves “heat training,” which can include exercise in heated environments or the use of saunas to trigger plasma volume expansion. This physiological shift allows the body to cool itself more efficiently and maintain a lower core temperature during the grueling climbs and flats of the Tour. For a powerhouse like Pedersen, who generates significant internal metabolic heat, this adaptation is the difference between maintaining a lead and fading in the final kilometers.
Tactical Implications for the Peloton
The synergy between de Jongh’s preparation and Pedersen’s execution has shifted how the rider is viewed in the peloton. No longer just a sprinter or a classics specialist, Pedersen’s ability to sustain high power in extreme heat allows him to be a threat in a wider variety of breakaways and finishes.
This physical resilience provides a tactical advantage. When rivals begin to suffer from heat exhaustion or “bonking” due to the temperature, Pedersen’s conditioned state allows him to apply pressure. This “architectural” approach to fitness means the rider is not merely reacting to the race but is physically prepared for the worst-case environmental scenarios.
Broader Context: The Modern Tour de France Landscape
Pedersen’s success is part of a larger, volatile battle for stage wins and jerseys. Recent race dynamics show a willingness from overall contenders to gamble. For instance, NOS reported that Tadej Pogačar has previously allowed breakaways to gain significant time, shifting the battle for stage victories to groups of riders who can sustain high speeds over long distances.
In this environment, riders like Pedersen—backed by the meticulous planning of de Jongh—are perfectly positioned. Whether fighting for a stage win or supporting a team strategy, the ability to withstand the “attrition” of the Tour is the primary goal of de Jongh’s system.
Comparison of Performance Drivers
While many riders rely on a general team physician or a standard training plan provided by the team, Pedersen’s relationship with de Jongh is more akin to a specialized partnership. The contrast lies in the level of personalization:

- Standard Team Approach: Broad training blocks applied to a group of riders to ensure a baseline of fitness for the whole squad.
- De Jongh’s Approach: Hyper-individualized “architecture” that treats the rider’s body as a specific engineering project, focusing on niche adaptations like heat tolerance and specific power-to-weight ratios for the Tour’s profile.
The Human Element: Resilience and Recovery
The Tour de France is as much a mental battle as a physical one. The discipline required to follow a “workaholic” coach like de Jongh requires immense mental fortitude. Pedersen’s ability to adhere to these strict protocols—often involving grueling sessions in uncomfortable conditions—highlights the trust between the athlete and the architect.
Recovery is the second half of this equation. De Jongh’s plans do not just focus on the “work” but on the precise science of recovery: nutrition, sleep, and active recovery protocols that ensure the rider does not enter a state of overtraining before the race even begins.
The next major checkpoint for the cycling world will be the official post-Tour performance reviews and the transition into the late-season classics, where de Jongh’s training blocks will be adjusted for shorter, more explosive efforts.
