How the 24 Hours of Le Mans works, from scrutineering to the chequered flag
A plain-English walk-through of the Le Mans race week: what the classes are, what happens each day, why the race runs for 24 hours, and how the winner is decided.
If you have watched a Grand Prix, the shape of a Le Mans weekend will look strange: the race starts in the late afternoon and finishes the next afternoon, and cars from several completely different classes share the same track at the same time. This article walks through the order of events so you can follow race week without a guide.
The basic shape of the race
The 24 Hours of Le Mans is an endurance race: the winner is the car that has completed the greatest distance in 24 hours. The organiser’s own schedule describes the race start on Saturday afternoon and the race running through the night until the following day, which is why the event is associated with a full day-and-night cycle on the same circuit.
The race is also the flagship round of the FIA World Endurance Championship. The championship’s own presentation states that the series was established in 2012 by the FIA and the ACO, and that its races last from six hours up to 24.
Several classes on one track at once
The most confusing thing about Le Mans for a new viewer is that the overall winner and the class winners are not the same thing. The organiser lists three classes:
| Class | What it is, per the organiser’s description |
|---|---|
| Hypercar | The top class since 2021, built to two rule sets: LMH and LMDh. LMH gives manufacturers freedom of architecture, including the option of a hybrid system on the front axle. LMDh is built on a common platform from Dallara, Multimatic, Ligier or Oreca. |
| LMP2 | A prototype class for independent teams. Four chassis suppliers (Dallara, Ligier, Oreca and Riley/Multimatic) all use a single engine supplier, Gibson. Each crew must include at least one Silver- or Bronze-rated driver. |
| LMGT3 | GT cars based on the FIA GT3 platform, introduced in the class line-up from 2024. The organiser states manufacturers must build more than 2,500 road cars a year to qualify. Each crew must include at least one Bronze-rated driver and one Bronze- or Silver-rated driver. |
A Hypercar can lap faster than an LMGT3 car, so during the race the two classes are constantly interacting: the faster car has to pass the slower one, and the slower car has to be predictable under blue-flag conditions. That traffic, multiplied over 24 hours, is a large part of what makes the race tactically interesting.
Race week in order
The organiser’s published programme for the 2027 edition lists days from Friday of one week through Sunday of the next, with the race itself on the second Saturday and Sunday. The listed race-day items include:
- A 15-minute warm-up on Saturday, described in the programme as the teams’ final chance to check details and adapt to the day’s conditions.
- A grid walk before the start.
- An official start ceremony, then the start of the race itself.
- Support races earlier in the programme, before the 24 Hours begins.
Sessions earlier in the week — practice and qualifying — are the part a first-time spectator underestimates. They are cheap to attend, usually far less crowded than race day, and they are when you learn where the cars slow down, which is exactly what you need on Saturday night.
Qualifying is not one session
The WEC results page breaks a race weekend into separate session results rather than a single qualifying classification. For a 2026 round the listed sessions include Free Practice 1, 2 and 3, then a Qualifying session and a Hyperpole session for each of the Hypercar and LMGT3 classes.
That structure matters when you read a timing screen: a driver at the top of a Free Practice sheet has not won anything. Hyperpole is the session that sets the front of the grid, and it is split by class.
Why the race is decided by distance, not by one lap
Because the winner is whoever covers the most ground in 24 hours, a car that is a few seconds a lap slower can still win by spending less time in the pits. Reliability and pit execution therefore carry as much weight as raw pace. This is the single biggest mental adjustment for a viewer coming from sprint racing: a car losing time at 2 a.m. is not necessarily out of the race, and a car leading at 2 a.m. is not necessarily safe.
What to take away
- Three classes race together: Hypercar, LMP2 and LMGT3, each with its own winner.
- The race is 24 hours long and starts on Saturday afternoon.
- Qualifying splits into Qualifying and Hyperpole, per class.
- Total distance, not single-lap speed, decides the result.
