How the Tour de France Works (It's Four Races at Once)

You turn on the Tour and see two hundred people cycling. Someone in yellow, someone in green, someone in polka dots, a group up the road, and commentators who assume you already know why any of it matters. Here's the thing nobody tells casual viewers: you're not watching one race. You're watching four of them happen simultaneously, on the same road, at the same time.

It's Not One Race — It's Four at Once

This is the single idea that turns the Tour from confusing to readable.

Every day, the same 180-odd riders cover the same road. But that one ride gets recorded on four different scoreboards, each measuring something different. A rider can be having a catastrophic day on one scoreboard and a brilliant one on another, at the exact same moment.

When a sprinter crosses the line 25 minutes behind the leaders on a mountain stage, he hasn't failed. He was never competing for that. He's saving himself for the flat stage in two days, where the person who just beat him by 25 minutes will be irrelevant. They're sharing a road, not a contest.

Once you know which scoreboard a rider is playing on, almost everything that looks strange starts making sense.

The Shape of the Three Weeks

The Tour runs 21 stages across 23 days, with two rest days. Each stage is a full race in itself, typically 150 to 220 km, and the winner gets the glory of the day.

But the overall competition works on accumulated time. The clock starts when you roll out of the first stage and effectively never stops until Paris. Finish a stage 40 seconds behind, and those 40 seconds go on your total permanently. There is no way to un-lose them except by taking time back somewhere else.

Which is why the yellow jersey contest is usually decided by a handful of minutes after roughly 80 hours of racing. Riders who look identical on television are separated by margins smaller than a coffee break.

The five kinds of stage, and who each one favours

Not all stages are the same race. The route designers deliberately mix stage types so that no single kind of rider can dominate, and so that the yellow jersey has to be earned in several different ways. Explore them below.

The Four Jerseys, Explained

Yellow — the one that means "winning the Tour"

The maillot jaune goes to whoever has the lowest cumulative time across every stage so far. Win the Tour and this is the jersey you wear in Paris.

It's yellow for a reason that has nothing to do with cycling: the race was founded in 1903 by a newspaper called L'Auto, which was printed on distinctive yellow paper. When they introduced a leader's jersey in 1919, they made it match the newsprint. A century of tradition, originating in a marketing decision.

Time is what matters here, not stage wins. It's entirely possible — and has happened — to win the Tour without winning a single stage.

Green — the sprinter's jersey

The maillot vert is a points competition, not a time one. Points are awarded for finishing position at the end of each stage, and again at an intermediate sprint partway through — a line drawn across the road mid-stage purely to create a contest.

The crucial detail is that the points are weighted by stage type. Winning a flat stage is worth 50 points; winning a brutal high-mountain stage is worth 20. The system is deliberately tilted towards the fast finishers, which is why green almost always goes to a sprinter who is nowhere near the top of the overall standings.

Polka dots — the king of the mountains

The white jersey with red dots goes to the best climber, decided by points collected at the summit of categorised climbs.

Climbs are rated by difficulty from category 4 (a modest hill) up to category 1 (severe), with the very hardest given a rating that translates as "beyond category" — hors catégorie. The label supposedly dates from an era when it described climbs a car couldn't manage. The harder the climb, the more points for whoever crests it first.

As for the design: the polka dots came from Chocolat Poulain, the sponsor when the jersey was introduced in 1975, whose wrappers were spotted. Again — a scoreboard wearing a sweet wrapper.

White — the best young rider

The maillot blanc is the simplest of the four: it uses exactly the same calculation as the yellow jersey — lowest total time — but only counts riders aged under 26.

It's effectively a preview of the next decade. Riders who win white tend to come back and win yellow a few years later.

Why doesn't one rider just win all four?

Because the jerseys reward physiques that pull in opposite directions.

A sprinter is powerfully built, carrying the muscle needed to produce enormous power for twenty seconds — muscle that becomes dead weight the moment the road tilts upward. A climber is featherweight, built to carry as little as possible up a mountain, and would be flattened in a bunch sprint. Asking one rider to win both is like asking a shot-putter to also win the marathon.

It isn't impossible to double up, though. Winning yellow, white and polka dots together has been done — a young overall contender who also happens to be the best climber in the race can take all three, since climbing is how the Tour is won anyway. Green alongside yellow is the combination that essentially never happens.

A practical note for watching: a rider can only wear one jersey at a time. If the yellow jersey also leads the climbing competition, he wears yellow, and the polka dots go out to whoever is second in that classification. So the jerseys you see on the road aren't always the standings — it's worth checking the actual classifications rather than the clothing.

Why It's a Team Sport That Looks Like an Individual One

Only one rider stands on the podium, but each team brings eight riders, and seven of them will spend three weeks working so the eighth can win. They're called domestiques — French for "servants," and originally an insult.

The physics that makes teams matter

At racing speed, the dominant force a cyclist fights is air resistance. Riding directly behind another rider puts you in their slipstream, and it can cut the effort required by roughly 30%.

Thirty per cent, sustained for five hours a day, for three weeks, is an enormous margin — larger than the gap between the best rider in the race and a decent one. This is the whole reason the peloton clusters into a tight, nervous blob instead of spreading out. Riding alone in the wind is a slow death.

What a domestique actually does all day

• Shields the leader from the wind for hours, so he arrives at the decisive climb fresher than his rivals.
• Fetches food and water — dropping back to the team car and ferrying up to a dozen bottles stuffed into their jersey.
• Chases down breakaways when a dangerous rival tries to escape.
• Sets a punishing pace on climbs to burn off the leader's rivals, then peels off, exhausted, having never been on camera.
• Gives up their own bike or wheel if the leader has a mechanical failure, then waits by the roadside for a spare.

A domestique might finish the Tour in 140th place having done more work than the man who won it. When you see a rider drift backwards out of the lead group looking destroyed, that's often not a collapse — that's a job completed.

The 2026 Edition: Barcelona to Montmartre

The 113th Tour is running right now, from 4 to 26 July 2026, and it's an unusual one on several counts.

It began with a Grand Départ in Barcelona — only the third time the race has started in Spain, after Bilbao in 2023 and San Sebastián in 1992 — including two consecutive stage finishes on the Montjuïc climb overlooking the city. Then it opened with a team time trial — the first at the Tour since 2019, and the first to open the race since 1971.

That last row is the story of this year's route. With almost no time trialling, there's nowhere for a strong-but-not-brilliant climber to claw back losses. The mountains decide everything, and 54,450 metres of climbing is more than six times the height of Everest.

The centrepiece is the finale. The race climbs Alpe d'Huez — the most famous ascent in cycling, 13.8 km at an average of 8.1% — on two consecutive days, on stages 19 and 20. Only once before has the Tour finished there twice in one edition. The second of the two arrives after the Croix de Fer, the Télégraphe and the Galibier, reaching the Alpe by the rarely used northern flank via the Col de Sarenne. Whoever is in yellow after those two days will almost certainly keep it.

Then Paris on 26 July, and even the finale has changed. The traditional closing procession down the Champs-Élysées now includes three laps of a circuit through Montmartre, the cobbled hill introduced last year after the 2024 Olympics showed how well it worked. The final stage used to be a ceremonial parade ending in a sprint. It isn't any more.

If you want to know exactly where the race is right now — stages completed, kilometres covered and how long until Paris — there's a Tour de France 2026 tracker that tracks it live.

What the Numbers Actually Mean for a Human Body

Some context for what you're watching. Riders average around 40 km/h across an entire stage — including the mountains — and burn somewhere in the region of 5,000 to 7,000 calories a day, roughly triple a normal adult's intake. Eating enough to stay alive becomes a genuine logistical problem, which is why you see riders constantly stuffing food into their mouths mid-race.

Those figures are worth putting into perspective against your own riding: an average speed calculator will tell you what a 40 km/h average would mean for your usual route, and a cycling calories calculator gives a sense of the daily energy cost. The comparison is usually humbling.

How to Watch a Stage and Know What's Going On

• Check the stage profile first. Flat means wait for the last 5 km. Mountains mean the real racing starts on the final climb.
• A breakaway is normal. A small group escapes early most days. Whether they survive depends entirely on whether the big teams want them caught.
• Ignore the gaps on flat stages. Riders finishing in the same group get the same time, so nothing has changed overall.
• Watch the yellow jersey's face on climbs. That's where the Tour is won and lost, usually in the last half hour.
• The rider dropping back isn't failing. He's probably a domestique who has just finished his shift.

The Takeaway

The Tour rewards patience in a way most sports don't. Nothing is decided in a moment; it's decided by accumulation, over three weeks, in seconds that pile up. A rider can dominate for eighteen days and lose it all on a mountain in the third week — which is precisely what this year's route, with its two ascents of Alpe d'Huez and almost no time trialling, is built to make happen.

Watch it knowing there are four races on the road and that most of the riders are working for somebody else, and the thing that looked like an incomprehensible crowd of cyclists turns into something you can actually follow.
