How difficult is it to complete a tournament? These data tell you.

It is almost impossible for amateur cyclists without training to complete any major circuit, but if we put aside the time limit, do professional amateur cyclists still have a chance? How difficult are the Tour de France, Tour Italy, and Tour Spain? Follow Wheelsall ( to look down.

These races are called Grand Tournaments for a reason. They are designed to test who is the best cyclist and team in the world. Let's see if an ordinary amateur cyclist has strength, strength, cycling skills, and even dietary ability.

Leg strength

Professional drivers consume more than 400W on average to maintain a speed of 40 km/h, which is even higher in time trials. Sprint drivers usually consume 1400W in the race. All this means that they can complete a 200-kilometer stage in 5 hours. In contrast, the average bicycle enthusiast can maintain an average power of about 200W and an average speed of 25km/h. This means that the same stage will take at least 8 hours.


Pain threshold

The super long distance of the Grand Tour not only caused great fatigue to the riders' legs, but also brought great pressure to their entire bodies. They test every muscle and joint of the body, especially the contact points, such as hands, feet and buttocks. An amateur who is not used to riding 200 kilometers a day will endure swelling, bruising, bleeding and a lot of pain just by riding a bicycle. In addition, crosswinds, roadside obstacles and crashes can also cause serious injuries. Professional riders often have small cuts, bruises, and abrasions on their knees and elbows, but they still need to continue racing.

Stomach capacity

So many days of high-intensity riding requires a lot of energy. It is estimated that during the three-week race, the driver burned more than 100,000 calories. This is equivalent to 275 Big Macs, 114 kilograms of steak or 56 kilograms of ice cream! In terms of food consumption, hardly any other endurance event on the planet can match the Grand Tour. Let's compare it with other sports.

IRONMAN: 7000-10000 calories (every 9 hours, one day of competition)
Grand Tour: 5000-8000 calories (per stage, 23 consecutive days)
Marathon: 2000-3500 calories (every 2-3 hours)
Swimming: 1500-2500 (swimming every 10 kilometers of open water)
From another perspective, an average person needs about 2000-2500 calories a day. Amateur cyclists may need 3000 to 4000 calories per day during training. And don’t forget to hydrate. Professionals usually drink up to 10 liters of water a day!


The Grand Tour also tested the drivers' ability to withstand general discomfort, and must face high altitude and lack of oxygen. They have to withstand changes in temperature and high-temperature weather for several days. They don't always ride on flat asphalt roads, and there are thousands of fans on both sides of the road. Compared to most amateur riders, they have little experience riding in such an environment.

Bicycle handling tips

Professional drivers often go downhill at a speed of 90km/h, and the smallest mistake can have fatal consequences. They must know how to ride on cobblestones effectively, and they must also be proficient in making road books and keeping up with the main group. Most hobby cars don't have superb downhill skills. In the end, they can only hold on to the brakes, with fear in their eyes, and go downhill at the speed of a snail.

Mental and physical

There is one place that contains almost all these challenges, and that is the mountain stage. Climb one of the legendary peaks, such as Alpe d'Huez, Le Mont Ventoux, Le Col du Tourmalet or Le Col de l'Iseran, at an altitude of 2,770 meters, which will enable most trained amateur climbers to reach them Physical and mental limits. Professional riders usually make multiple such climbs in a day, and then climb the Alps and Pyrenees for several days.
