What is a stint in endurance racing?
What is a stint in WEC? Understand fuel stints, tyre stints, driver runs and why a pit stop does not always mean changing drivers or tyres.
A driver completes a double stint, the team keeps the same tyres, and the car still visits the pits. Endurance racing's terminology can sound contradictory until you identify what is being measured.
In WEC, a stint usually describes a period of running between pit visits. Drivers and commentators also use the word when discussing tyres or a driver's uninterrupted spell behind the wheel.
What is a fuel stint?
A fuel stint is the running completed between refuelling stops. Its length depends on consumption, the circuit, conditions and the team's strategy.
For a Hypercar, physical fuel and permitted stint energy must both be managed. The virtual energy tank tracks the latter.
There is no universal number of minutes or laps that defines every WEC stint.
What does double-stinting the tyres mean?
Double-stinting means using the same tyres across two successive running stints, normally with a refuelling stop between them.
The car can therefore pit without receiving a fresh set. If tyre condition allows, the time saved in the pits may outweigh the performance benefit of new rubber.
Tyre strategies need not treat all four corners identically. Before Barcelona's 2026 race, Michelin anticipated teams potentially double-stinting right-side tyres while changing the more heavily stressed lefts after one stint.
Does the driver change at every stop?
No. A driver can remain onboard through a refuelling stop and continue driving.
Consequently, a driver completing two consecutive stints does not necessarily mean the tyres also complete two stints. The team can retain the driver while changing the tyres, or change drivers while retaining them.
Those are separate strategic decisions.
How does WEC measure driving time?
The 2026 sporting rules add together a driver's individual periods of running. Pit-stop time and red-flag suspensions are excluded from actual driving time.
Specific driving-time requirements depend on the category and event. Do not apply a six-hour race's requirements automatically to Le Mans.
What should viewers watch?
Track the last refuelling stop, tyre changes and driver changes separately. That reveals whether a car has genuinely extended its range or simply continued with the same driver.
Our WEC race coverage provides the context behind those decisions.
