Five laps in the Genesis made Jamie Chadwick the first woman to drive a Hypercar at Le Mans.
Five laps was all it took. On Test Day at the Circuit de la Sarthe, Jamie Chadwick drove the number 17 Genesis GMR-001 as the team's reserve driver, and the ACO confirmed on June 9 that she is the first woman to drive a Hypercar at Le Mans since the class was created. The stint was an installation run by any sporting measure. By every other measure it moved a boundary that had stood through five years of the Hypercar era.
Chadwick was not handed a demonstration run for the cameras; she holds the seat Genesis Magma Racing turns to if one of its race drivers cannot start, which makes her one medical certificate away from racing the top class of the 24 Hours. Her route here ran through the place most top-class careers run through: she raced La Sarthe in LMP2 with IDEC Sport in 2025, three seasons after her third W Series title closed the single-seater chapter. The progression from prototype undercard to Hypercar reserve took one year.
In 1930, Marguerite Mareuse and Odette Siko became the first women to start the 24 Hours, a lineage the ACO's own report traces across 96 years to this week. Women have raced at Le Mans in every era since, through GT classes and prototypes, and the modern record has been built largely in LMP2 and LMGT3 machinery. What never happened until Sunday was a woman driving the class that wins the race overall. Chadwick crossed that line on Sunday, which is why a Test Day stint carries a news cycle.
Genesis supplies the second layer of the story. The GMR-001 is itself a debutant this week, the Korean marque's first Le Mans entry, a programme Paddock Notes covered at its June 3 unveiling for building its race engine off rally-programme architecture. A first-time manufacturer handing its reserve laps to the driver who crossed that line is a choice about what kind of racing brand it intends to be, made before the brand has a single race result. New entrants usually spend their first 24 Hours trying not to be noticed. Genesis has now been noticed twice before the green flag.
The machinery underneath the milestone is not a backmarker, either. A GMR-001 ran inside the Test Day top ten on June 7, Motorsport.com's session report shows, on a day when all eight Hypercar manufacturers finished within a second of each other. Reserve laps in a midfield science project would be a footnote. Reserve laps in a debut car running competitive times at the dress rehearsal are a credential with a timestamp.
Doriane Pin makes it a two-thread weekend. The Mercedes Formula 1 development driver lines up on this year's LMP2 grid in the number 30 Duqueine Oreca, the ACO notes in the same report, which puts two of the most credentialed women in circuit racing at the same event on adjacent rungs of the same ladder. Pin is 22 and climbing through the prototype ranks with factory single-seater backing; Chadwick is 28 and one step from a Hypercar race seat. The pipeline conversation at Le Mans usually concerns which LMP2 drivers graduate to the top class. This year that conversation includes two women, at different stages, simultaneously.
Scale matters for what comes next. The 94th running carries a 62-car entry confirmed by the FIA WEC, 18 of them Hypercars from eight manufacturers, and the race runs June 13 to 14 with the full week's track schedule opening Wednesday. Eighteen top-class cars means 54 race seats, and the question Chadwick's five laps pose is plainly arithmetical: when does one of those 54 names belong to a woman? The reserve role is how endurance racing answers that question in practice. Seats in this discipline are filled from the bench, and the bench now has a precedent on it.
Chadwick's 2025 LMP2 season answers the obvious skepticism about milestone framing. Endurance racing does not hand top-class drives to symbols; it hands them to drivers whose stint times, traffic management and tyre life survive a 24-hour audit, and her IDEC Sport campaign was that audit at the class below. The reserve appointment is Genesis reporting the result. The five laps were not the test. They were the receipt.
Practice opened Wednesday at 14:00 local and the two-round Hyperpole follows Thursday, so the car Chadwick tested will have a grid slot with a number on it before the weekend arrives. The race week carries its own questions: whether the GMR-001 survives its first 24 Hours, whether Pin's Duqueine entry runs at the front of an LMP2 field full of graduation candidates, and whether any of the 18 Hypercar crews need their bench before Sunday afternoon.
