Tour de France Training Secrets: How Pro Riders Prepare

Covering roughly 3,400 kilometers over three weeks with more than 50,000 meters of cumulative climbing, the Tour de France is the ultimate test of human endurance. Every rider who lines up on that start line has undergone a year or more of systematic preparation. But how exactly do they train? How many kilometers do they ride each day? How do they structure intensity and recovery? This article takes you deep inside the training world of professional riders.

The Annual Training Framework of Pro Riders

The training plans of top professionals are typically built on “Annual Periodization,” dividing the year into distinct phases, each with clear training objectives.

Post-Season Transition Period (October–November)

The Tour de France ends in July, and riders with longer seasons may race all the way through the Vuelta a España in October. After the season concludes, riders need 4–6 weeks of “active recovery”: completely stopping systematic training and only doing easy spins or taking full rest. After months of physical and mental exhaustion, forced rest is actually the key to long-term performance gains.

Many riders use this period to try other sports such as swimming, hiking, or skiing—maintaining baseline fitness while avoiding overuse injuries to specific muscle groups.

Winter Base Period (December–February)

Winter is the golden window for building the aerobic foundation. The hallmark of pro training in this phase is “high volume, low intensity”—weekly riding distance can reach 1,000–1,400 kilometers, but intensity stays primarily in heart-rate zones 1–2 (55–75% of maximum heart rate).

Behind this seemingly easy training lies a purpose: increasing mitochondrial density and improving fat-burning efficiency to lay the physiological groundwork for later high-intensity work. As performance coaches often say: “The stronger your aerobic base, the higher your ceiling for intense efforts.”

Many riders from Northern Europe (such as Norwegian and Danish athletes) use smart trainers paired with simulation software like Zwift during winter to maintain training while avoiding the injury risk of riding in harsh weather.

Spring Build Period (March–April)

Spring is the testing ground for team strategy. Pro riders begin racing smaller stage races (such as Paris–Nice, Tirreno–Adriatico, and the Volta a Catalunya), using competition to validate winter training, refine tactical coordination, and let the body adapt to race-intensity rhythms.

This phase introduces more “threshold training” and “VO2max intervals”: under precise power-meter monitoring, riders complete sustained high-intensity efforts of 5, 8, and 20 minutes, systematically pushing up their lactate threshold and maximal oxygen uptake.

Race Season Peak (May–July)

This window marks the “competitive peak” for pro riders. To ensure peak form for July’s Tour de France, preparation typically includes:

Altitude Training Camps: Spending 3–4 weeks at training bases located 1,800–2,500 meters above sea level, using the hypoxic environment to stimulate red blood cell production and improve oxygen-carrying capacity. Sierra Nevada (Spain), Livigno (Italy), and Mount Teide (Canary Islands) are among the most popular altitude venues.

Simulated Tour Mountain Stages: Teams “replicate” key Tour de France climbs in training, running simulations at target race pace so riders have already “seen” the decisive terrain before the real race begins.

Pre-Race Tapering: In the 2–3 weeks before the Tour starts, training volume gradually decreases while maintaining some high-intensity sessions to preserve competitive sharpness. Over-tapering can leave riders feeling flat—it’s a science that demands precise calibration.

The Power Meter: The Core Tool of Modern Training

Modern professional cycling training is almost entirely driven by the power meter. Power (watts) is the most precise measure of training intensity—unaffected by weather, terrain, or wind—allowing riders to execute exact training prescriptions under any conditions.

Top Tour contenders typically have an FTP (Functional Threshold Power) of 380–430 watts at a body weight of 60–70 kilograms, translating to a power-to-weight ratio of approximately 6.0–6.5 W/kg—far beyond the 3–4 W/kg of the average amateur rider.

Nutrition Strategy: What to Eat, When to Eat

During the Tour de France, riders burn 7,000–9,000 calories per day—equivalent to 3–4 days’ worth of intake for an average adult. Figuring out how to replenish that energy without causing gastrointestinal distress is another core skill for pros.

In-race fueling: 90–120 grams of carbohydrate per hour (using a 2:1 ratio of glucose to fructose), delivered continuously through energy gels, energy bars, rice balls, and bottles handed up from team cars.

Recovery nutrition: Within 30 minutes of finishing each stage, riders consume a high-carbohydrate, high-protein recovery drink to accelerate muscle glycogen replenishment and prepare for the next day’s stage.

Sleep and Recovery: The Underrated Training Component

Pro riders need 9–10 hours of sleep per night, plus 1–2 hours of napping during the day. Sleep is the golden window for muscle repair, hormonal regulation, and neurological recovery—the cumulative fatigue of the Tour can only be effectively processed through adequate rest.

Many top teams also employ cryotherapy (ice baths or cold-water immersion), compression leg sleeves, and daily full-body massage from professional therapists to accelerate recovery and keep riders competitive throughout the three-week race.

Conclusion: Preparing for the Tour Is a Year-Long Story

The moment of winning the Tour de France may last only a few hours, but the story of preparation behind it spans an entire year. From lonely base training in winter, to the crucible of spring racing, to the transformation of altitude camps—every piece is indispensable. Understanding these training secrets not only deepens our admiration for those who win, but also offers valuable training inspiration for every Taiwanese cyclist who loves the sport.
