IRK RONE · Endurance Race Race⏱ 4h51

The 7 Laghi Kart circuit in Castelletto di Branduzzo (PV) hosted a demanding 291-minute endurance race on 1 August 2026, with 46 starters battling it out on the 1,256-metre layout. When the chequered flag fell, Maximilian Schieder (kart 6) took the overall victory with 381 laps completed and just 6 pit stops — the most laps of the entire field.

Matteo Grappolini (kart 27) crossed the line in second place, 4 laps down, also on 6 pit stops, while Dennis Holler (kart 1) rounded out the podium in third, 6 laps behind and with 7 pit stops. The top five was completed by Alessandro Grilli (kart 10) in fourth at 7 laps and Rob Freckleton (kart 15) in fifth at 8 laps. The absolute fastest lap of the race — 1:02.226 — was set by Alessandro Grilli (kart 10).

The pace analysis reveals a striking gap between finishing position and pure pace for the race winner. Maximilian Schieder ranked only 4th in median race pace (1:03.008), with a consistency standard deviation of 0.35 s across 7 stints — all rated stable. His victory was built on exemplary strategic execution: 6 pit stops, minimal time lost, and an ability to maintain an unwavering pace throughout the 291 minutes.

The most notable contrast belongs to Matteo Grappolini (2nd), who ranked only 33rd in pure pace with a median of 1:03.662 and a regularity of 0.72 s — the weakest among the top 10 analysed. His runner-up finish is a textbook example of strategic gain: the same 6-stop plan as the winner, capitalising on the attrition suffered by faster rivals.

At the other end of the spectrum, Lorenzo Manfredotti (kart 58) posted the best pure pace of the entire race — a median of 1:02.749 — with a solid regularity of 0.42 s across 8 stints. Yet he could only manage 7th place on the road, held back by 8 pit stops and time lost in the pits.

Dennis Holler (kart 1) stood out as the most consistent driver of the race, with the lowest standard deviation in the top 10 at just 0.33 s, and the 2nd best pure pace (median 1:02.948). His 8 stints were all stable, confirming a flawless mechanical management of the kart — yet a stop more than the winner cost him a place on the top step.

Daniele Rossi (kart 4) deserves a mention: ranked 3rd in pure pace (median 1:03.007, regularity 0.45 s) but finishing 10th, penalised by 8 pit stops and time lost on strategy. Similarly, Nicolas Serafini (kart 30) achieved the 5th best median pace with only 5 pit stops — the fewest in the analysed group — but finished 9th, suggesting pit stop duration or traffic weighed against him.

Key takeaways for teams: at 7 Laghi Kart in endurance format, pit stop count and execution prove decisive — Schieder's win on 4th-best pace illustrates this perfectly. Controlling the number of stops while maintaining sub-1:03.0 median pace is the optimal target. Consistency (σ below 0.40 s) appears more valuable than peak speed: Holler's 0.33 s deviation and Schieder's 0.35 s confirm it. Teams with high regularity variance (Grappolini at 0.72 s, Freckleton at 0.64 s) must review how they manage longer stints to avoid losing ground to more controlled rivals.
