The 66-minute endurance race at Dunois Kart in Lutz-en-Dunois brought together 16 teams on the 1,200-metre circuit on 11 September 2026. After 51 laps of racing, it was RAIKKONEN (kart #19) who crossed the line first, ahead of SAINZ and PROST in a tightly contested finish at the top of the leaderboard.

RAIKKONEN took victory with a 6.765-second margin over SAINZ (kart #24), who in turn finished 3.274 seconds clear of PROST (kart #5) in third. ROSBERG (kart #3) and OCON (kart #15) completed the top five, all finishing on 51 laps. VETTEL (kart #16) rounded out the lead lap in sixth, finishing over a minute behind the leader. Each of the top six teams made 3 pit stops during the race.

The fastest lap of the race was set by PROST with a time of 1:03.764, the quickest single lap recorded across the entire event. On pure median pace, however, it was VETTEL who posted the best race rhythm at 1:04.959 — the fastest of any team — yet finished only sixth. This gap between raw pace and final position is the defining storyline of the race. VETTEL's two slower stints (relais 2 and 4, medians of 1:09.210 and 1:08.082 respectively) cost them dearly, inflating their overall standard deviation to 2.36 seconds — the highest inconsistency among the frontrunners.

SAINZ produced the second-best median pace (1:05.249) with the most consistent performance in the leading group (σ = 0.93 s), all four stints rated stable. VERSTAPPEN (kart #2) is arguably the race's most striking case: 3rd-best median pace at 1:05.277 across only three stints, yet finishing 11th — 3 laps down. Their race was clearly compromised, as illustrated by a final classification far below their pure speed potential.

At the other end of the spectrum, ROSBERG was the most consistent team on track, recording the lowest standard deviation of all finishers at σ = 0.88 s over four stints, despite sitting only 6th in pure pace. Their controlled approach secured a solid 4th-place finish. BOURDAY (kart #9) finished 7th with 50 laps, an noteworthy result given their 13th-best median pace (1:07.538) — testament to solid strategy and execution despite limited outright speed.

Among the notable performances further back, FANGIO (kart #10) showed the sharpest pace degradation of any team, losing 0.31 s per lap in their final stint, which ultimately cost them positions in the closing stages. LECLERC (kart #1) finished 8th but completed only 27 laps, suggesting their race was cut significantly short, while GASLY (kart #13) ended the day 10 laps off the pace in 16th with 41 tours.

Key takeaways for teams: At Dunois Kart, inter-stint consistency proved at least as important as outright speed. VETTEL's case shows that the fastest median pace is worthless without regularity across all stints. The winning RAIKKONEN team achieved victory not through the sharpest times, but through four remarkably stable stints (σ never above 2.14 s, and as low as 0.53 s in relais 3). Managing pace across every stint, not just the fast ones, is the true key to endurance success on this circuit.
