Tour de France: 10 Wacky Rules of the Greatest Cycling Race in the World

Riders must constantly jockey for positions with the athletes around them to gain every possible advantage. The Tour de France’s workings can be a bit tough to understand in its own right.

However, in addition to the complicated race format, the Union Cycliste Internationale (UCI) regulates the race and has precise rules that all riders and team members must follow. Some restrictions, like not cutting the course, seem obvious. Others seem arbitrary, unnecessary, or downright weird.

Here are a few of the strangest rules Tour de France riders must follow.

No Littering in the Tour de France

Bikes are good for the environment, right? So races should be, too. Per UCI guidelines, athletes face hefty fines and point deductions if they toss gel packaging, bottles, clothing, or trash outside designated zones outlined by race officials.

A handful of riders always seem to break this rule and get fined in every Tour de France. The UCI levies punishment for littering when an offense meets the following criteria:

“*(A) Rider or team staff disposing of waste or other objects outside of litter zones, or not returned to team or organisation staff, not collected by team staff, thrown at a spectator. Disposing waste or other objects in a careless or dangerous manner (e.g., bottle or other object remaining or bouncing back on the road, thrown directly or with excessive force at spectator, causing dangerous manoeuvre by other rider or vehicle, causing spectator to move onto the road).”

The first infraction amounts to roughly a $500 fine and a 25-point deduction from the UCI rankings. A second infraction comes with a $1,000 fine and a 50-point deduction in UCI rankings. A third offense is a bit nastier. It results in a $1,500 fine, a 75-point deduction in UCI rankings, and elimination or disqualification from the race.

No Pushes From Spectators

The UCI prohibits pushing off of cars, motorcycles, or riders. It also prohibits riders and spectators from pushing other riders.

Fans frequently run beside riders to offer support, particularly during grueling climbs. But a push can have severe consequences for a rider, including a 20% penalty in the points classification for sprints (green jersey) or in King of Mountain (KOM) classifications (polka-dot jersey) and a 10-second penalty per infraction.

Team Car Distance Behind Riders

In a logical extrapolation of the above rule, drafting behind team vehicles is prohibited because of the obvious drafting advantage. However, there is also a rule about the distance a team car can follow a rider. The rule states that a car must follow at least 25 m behind riders during time trials. This may seem like an unnecessary rule at first, but science proves otherwise.

Studies show that a car closely following a rider can push the rider forward via an “air cushion” that builds in front of the car as it travels forward. Riders and teams knew this before the UCI mandated the follow-car distance. Before the UCI exercised this regulation in 2023, support cars followed individual cyclists in time trials festooned with 10 spare bikes in an almost hysterical attempt to enlarge the air cushion.

You can’t blame a team or rider for trying, but it’s officially not allowed now.

No Spraying Liquid From Cars

Sometimes, stages get hot. It’s common to see riders spraying themselves with their bottles to get their core temperature down.

The UCI has no problem with riders giving themselves a refreshing spray, but if someone gives them one from a team car, for some reason, a bridge too far. The UCI fines drivers about $200 per infraction for giving riders a spray on the course.

No Public Urination or Undressing

Nature will call if you’ve been on a bike for several hours and ingested enough liquid to float Noah’s ark. It’s normal for riders at the Tour de France and other grand tours to stop to relieve themselves during portions of races where they still have time to catch up with the peloton.

According to UCI rules, however, this is a no-no. If race officials identify a rider urinating in sight of the public, sometimes on the bike with a helping push from a teammate, they can levy a fine of about $200 to $500. Riders often stop in large packs to relieve themselves simultaneously, so race officials can’t get them all.

No Assistance From Other Teams

If you wonder whether cyclists competing in grand tours have any honor, sometimes it just isn’t allowed. Per UCI rules, riders cannot receive assistance from other teams during races. This rule comes with a significant punishment as well. Riders can be penalized anywhere from 2 to 10 minutes per infraction, with a roughly $500 fine.

Two minutes is a massive margin in a stage race like the Tour de France. That kind of deficit could be a nail in a rider’s coffin, even if they are at the front of the pack.

Richie Porte learned this lesson the hard way in 2015 when the UCI fined him $200 and gave him a 2-minute penalty during the Giro d’Italia for accepting a wheel from a racer on another team in the last bit of Stage 10 after he blew a tire. He later abandoned the race.

No Personal Clothing During Podium Obligations in the Tour de France

When the ride is over, most cyclists are ready to strip out of their tight-fitting Lycra as soon as possible. Tour de France cyclists are not so lucky.

The UCI requires riders to wear their complete racing kit during podium obligations, including each day’s sign-in and the team presentation ceremony. That means some riders will stay in their tight racing outfit for long outside the race, before and after.

Wearing the wrong clothing to the podium can result in about a $500 fine for a rider or sports director.

No Feeding Outside of Designated Zones

Riders need to pump their bodies full of nutrition throughout races to remain competitive, but they are not allowed to feed (receive food) whenever they want. Feeds to riders must occur in designated areas.

The UCI penalizes riders who feed in the first 30 km and last 20 km of stage races, including the Tour de France. Those caught feeding in the first stretch face about a $200 fine. Those caught in the last stretch pick up the same fine and a 20-second time penalty.

Any more infractions come with about a $1,000 fine per infraction.

Sock Height in the Tour de France

Yep. The UCI will come for your socks. The UCI in 2018 noted that riders’ socks must not extend more than halfway up a rider’s shin.

Here’s how they put it: “Socks and overshoes used in competition may not rise above the height defined by half the distance between the middle of the lateral malleolus and the middle of the fibula head.”

The idea is to limit riders’ aerodynamic advantage from their footwear. However, socks are pretty low on the priority list if current aero helmets indicate how riders try to find the perfect aero system.

No Indecent Behavior Toward Spectators

The UCI wants spectators and riders to get along. So, any form of “assault, intimidation, insults, threats, improper conduct (including pulling the jersey or saddle of another rider, blow with the helmet, knee, elbow, shoulder, foot or hand, etc.), or behavior is indecent, or that endangers others” is expressly forbidden.

Riders face fines from $200 to $2,000 for any infraction against another rider or spectator.

And One Golden Unwritten Rule: Respect Yellow

This entry into the wacky rules isn’t an official rule, but it might as well be. The easiest way to state it is that the overall race leader’s yellow jersey must always be respected. If the race leader crashes, has a mechanical, needs a nature break, etc., competitors are not to attack or put the yellow jersey in “undue” difficulty.

This unwritten gospel creates many of the Tour de France’s most memorable moments, both good and bad. Many rivalries are bitterly contested, only to melt into pure humanity when the yellow jersey crashes and the rivals wait.

Not heeding this cultural line in the sand may be more costly than breaking an official rule. Alberto Contador attacked yellow jersey wearer Andy Schleck during the 15th stage of the 2010 Tour de France, and the video still comes up in race coverage as an example of seedy tactics.

Conversely, the yellow jersey wearer must also respect the golden fleece by acting similarly. Most recently, in the 18th stage of the 2022 Tour de France, racer leader Jonas Vigegaard waited for second-placed rival Tadej Pogačar, who crashed while attacking on a mountain descent. The two shook hands when reunited and continued leading the stage together. What a show of class. Vingegaard ultimately claimed the victory that day.
