The Circuito di Siena hosted a demanding endurance race on 24 October 2026, with 38 teams taking the start on the 1,037-metre circuit for a race lasting nearly 587 minutes. At the finish, GOATS RED (kart #4) claimed the victory with 599 laps completed, holding off PF RACING (kart #1) by 30.806 seconds in an identical lap count. KARTEL (kart #11) rounded out the podium one lap down.

The top of the order was remarkably tight. PF RACING matched GOATS RED's 599 laps but could not close a gap that held at 30.8 seconds to the flag. KARTEL finished third at 1 lap, BREMO 58 (kart #58) fourth at 2 laps, and KARTEL SPORT (kart #12) fifth at 3 laps. In the battle for sixth through tenth, GOATS BLACK, TEAM LIECHTENSTEIN, BREMO 69, GOATS WHITE and NEXUS RACING all finished on 595 laps, separated by just over 31 seconds between sixth and tenth place.

In terms of pure pace, the analysis reveals a more nuanced picture. GOATS RED posted the 2nd-best median race pace (55.730 s) and the best overall consistency among the top finishers, with a standard deviation of just 0.64 s across 11 stints. Their strategy of 11 pit stops proved well-calibrated: all 12 stints showed a stable pace trend, and their best individual stint median reached 55.480 s in stint 6. Their combination of competitive pace and flawless management was the decisive factor in the victory.

PF RACING ran 13 pit stops — two more than the winner — with a median race pace of 55.821 s (3rd-best). Their more fragmented strategy did not prevent a strong runner-up result, though the additional stops ultimately kept them behind GOATS RED. KARTEL produced the race's longest individual stint (112 laps, repeated in both stint 1 and stint 10), underlining a bold low-stop strategy of only 10 pit stops, but their 4th-best median pace (55.891 s) was not quite enough to challenge higher up.

One of the most striking strategic contrasts came from NEXUS SPORT (kart #30), which finished 14th overall despite ranking only 21st in pure pace — a clear sign of effective pit-stop management over the course of the race. Conversely, GOATS WHITE (kart #26) showed the race's most significant pace degradation within a single stint, losing 0.42 s per lap through stint 9, which may have cost the team positions in the final classification.

The most consistent team across the entire race was ROMA KARTING SEVEN (kart #7), which recorded the lowest standard deviation of all analysed teams at 0.62 s, finishing 12th — a testament to the value of regularity in endurance racing. The fastest lap of the race was set by TEST (kart #50) in 54.312 s, though that team finished 32nd on classified laps (339 laps), underlining that raw speed without distance is not enough.

Key takeaways for teams: At Circuito di Siena, a well-paced strategy with minimal stop count (10–11 pit stops) consistently outperformed higher-stop approaches. Maintaining a stable pace throughout each stint — avoiding degradation in the closing laps — was critical. Teams with a pure-pace advantage but inconsistent stints or excessive pit stops lost multiple positions by the flag. Managing the balance between stint length and tyre performance appears to be the central strategic lever on this 1,037-metre circuit.
