French tricolor to start the race before 325,000 spectators at 16:00
CEST, which was led by the pole-sitter Nicklas Nielsen's No. 50 Ferrari. A total of 62 cars were scheduled to start the race, The larger Hypercar field and driver behaviour meant greater risks were made while lapping slower vehicles.
Mark Kvamme spun the No. 32 Inter Europol car into the gravel trap. Under the safety car, repairs to the barrier and debris cleanup took 35 minutes as Aitken returned to the garage for repairs and Kvamme was extricated from the gravel. Following Aitken's incident,
Daniil Kvyat's second-placed No. 63 LMP2 Prema car entered the pit lane for a lengthy stop to remove debris in the air intake. Catsburg drove the No. 33 Corvette into the garage during the second hour to repair a faulty front-right
damper and Keating rejoined the race two laps down in LMGTE Am. Accidents for Sales' No. 14 Nielsen car into the outside tyre barrier approaching Dunlop corner, which removed the car's front-right, and
Ricky Taylor's No. 13 Tower vehicle against the inside barrier at high speed in Arnage turn prompted the retirement of both cars and the implementation of a slow zone. Midway through the second hour, De Pauw's No. 21 AF Corse Ferrari was caught out by Bourdais' No. 3 Cadillac slowing for the slow zone and rammed into Bourdais' rear under the
Dunlop Bridge. Gustav Birch's No. 55 GMB Aston Martin was also involved in the incident, and both his and De Pauw's cars were retired. While Bourdais drove the No. 3 Cadillac to the garage for rear-end repairs, Birch and De Pauw were unhurt. Heavy rain fell from Indianapolis corner to the start/finish straight before the end of the third hour, and several vehicles were caught off guard by the sudden drop in grip while braking and leaving turns on slick tyres. Pera's LMGTE Am-class leading No. 86 GR Porsche spun rear-first into the inside barrier. After the safety car period ended, Ye's No. 38 Jota Porsche moved from sixth to the race lead into Indianapolis corner. Cameron moved the No. 5 Penske Porsche to second overall before being passed by the Ferrari 499Ps. He was imposed a drive-through penalty for passing the No. 100 Walkenhorst GTE Ferrari during the safety car period. Ye lost the overall lead when he lost control of the No. 38 Jota Porsche, removing its rear end assembly and engine cover in a high-speed sideways impact against the tyre barrier leaving the Porsche Curves. The car was repaired in the garage by mechanics for 20 minutes and four laps and Giovinazzi's No. 51 Ferrari took the lead. The debris on the circuit caused a Full Course Yellow. Heavy rain again fell on parts of the circuit and reduced visibility in the seventh hour and more vehicles were caught out by the changing conditions as they made pit stops for wet-weather tyres. Petrobelli got the JMW Ferrari beached in the gravel at Karting turn, causing heavy rear-end damage and requiring extrication. The car lost the LMGTE Am lead to Iron Dames' Gatting before being passed by Cairoli's No. 56 Project 1 car. Rasmussen's No. 28 Jota car had a frontal crash in the Porsche Curves but drove slowly to the pit lane for repairs and Scherer's No. 34 Inter Europol car took the LMP2 lead in the seventh hour. Pier Guidi then lost control of the race-leading No. 51 Ferrari while attempting to avoid colliding with the No. 911 Proton Porsche that had hit a Glickenhaus ahead of him in the Daytona Chicane. He recovered with vehicular assistance and lost the race lead to Müller's No. 94 Peugeot.

safety car period. Kobayashi slowed at Tertre Rouge corner in the ninth hour to avoid passing
Giedo van der Garde's No. 39 Graff car into a slow zone enforced for Pier Guidi's accident. Prette's JMW Ferrari was caught off guard by Van der Garde and hit the No. 7 Toyota's left rear, while
Memo Rojas' No. 35 Alpine struck the Toyota's right rear. Prette collided with the rear of Van der Garde's car, causing race-ending damage to the JMW Ferrari and the No. 7 Toyota. Although no driver was hurt, Prette was taken to the medical centre for evaluation. A third safety car period was used to allow marshals to clear debris at Tertre Rouge corner and to recover the damaged cars. The accidents promoted Bamber's No. 2 Cadillac to third and Pier Guidi's No. 51 Ferrari to fourth. Because a large piece of Kevlar became caught in the suspension and blocked the cooler's flow, the No. 8 Toyota's engine began overheating at the same time as the No. 7 car's collision. Fuoco entered the garage to repair a front leak caused by a stone damaging the front-right brake
radiator. Calado used the No. 51 Ferrari's better straightline pace on the straight into the Indianapolis turn to pass Müller's No. 94 Peugeot on the inside and take second place. De Gerus damaged the No. 37 Cool entry's front-left and rear-left suspension against the barrier at the exit to the first opening of the Porsche Curves during the 13th hour. He brought the car into the garage to be retired with tub damage.

Ben Barnicoat's No. 80 AF Corse LMP2 Pro/Am car attempted to overtake slower vehicles through the Porsche Curves not long after. Kessel's No. 57 Ferrari had become the LMGTE Am leader by this stage thanks to steady pace from drivers Serra and Huffaker, as well as pit stop strategy. While lapping the No. 31 WRT LMP2 entry in the 17th hour, Estre's No. 6 Porsche hit the inside kerb in the Porsche Curves, severely damaging the car's floor against the tyre barrier. The car dropped out of a duel for fourth with Bourdais' No. 3 Cadillac after 43 minutes of bodywork and floor repairs in the garage. LMP2 remained a battle between Kubica's No. 41 Jota and Smiechowski's No. 34 Inter Europol cars, while LMGTE Am was a duel between Iron Dames' Frey and Project 1's Cairoli, and Catsburg and Keating's No. 33 Corvette moved to third in class after returning to the lead lap through pace and a safety car wave-by as the circuit dried. Pier Guidi's No. 51 Ferrari lost the lead to Buemi's No. 8 Toyota because he needed to power cycle the No. 51 Ferrari, which had difficulty restarting from his pit box due to a cockpit communications system failure, but reclaimed it by passing Buemi on the outside through slower LMP2 traffic into the second Mulsanne chicane. The gap between both drivers was small until Molina's No. 50 Ferrari attempted to regain a lap from Hartley's No. 8 Toyota, allowing Calado's No. 51 Ferrari to pull away. Actor

Varrone's 33 Corvette set a series of quick laps to take the LMGTE Am lead from Bovy's No. 85 Iron Dames Ferrari and the No. 25 ORT by TF car of Al Harthy.

Mikkel Jensen's No. 93 Peugeot entered the garage with a hydraulics issue. Hirakawa, who replaced Hartley, spun into the left-hand side guardrail barriers entering the right-hand Arnage corner after locking the rear brakes in the
braking zone due to a rearward brake balance setting that he was unaware of with 1 hour and 45 minutes remaining. He entered the pit lane to have mechanics replace the damaged front and rear bodywork before rejoining the track nearly a lap behind Giovinazzi's No. 51 Ferrari. In the 23rd hour, Iron Dames lost second in LMGTE Am to Eastwood's No. 25 ORT by TF car who passed Frey's No. 85 Iron Dames Ferrari on the inside into the first Mulsanne chicane after a short battle and began pulling away. Although the No. 51 Ferrari underwent a system reset at its final pit stop in the final hour, They finished 1 minute, 21.793 seconds ahead of the No. 8 Toyota, with the No. 2 Cadillac finishing one lap behind in third place, despite losing time due to frequent oil replenishing during pit stops arising from an engine oil issue from the third hour. earning their first WEC LMP2 victory and second since the ALMS 4 Hours of Dubai.
