🇧🇪 Guido Dumarey

Guido Dumarey is a semi-professional endurance racing driver competing in multiclass championships at the Nürburgring. Racing for PROsport Racing, he drives GT4 cars in the Nürburgring Langstrecken-Serie and the Nürburgring 24 Hours, and has also contested the 24H Series; he holds an FIA Bronze grade, the amateur classification in endurance racing. His career spans eight seasons from 2019 to the present.[1]

Dumarey has accumulated 37 starts across these three series with five podium finishes. The bulk of his racing comes in the Nürburgring Langstrecken-Serie, where he has made 30 starts and taken four podiums over that period. He has started the Nürburgring 24 Hours six times and scored once; he made a single appearance in the 24H Series in 2022. His current season includes his ongoing participation in the 2026 Nürburgring 24 Hours.[2]

In the competitive field, Dumarey is closely matched with Andreas Gülden, a Bronze-graded professional who won the Nürburgring Langstrecken-Serie SP 10 class in 2024 and has been a regular opponent across these series. He typically finishes behind Michael Tischner, an entry-level professional also racing the same championships. Against the broader grid of amateur and semi-professional entrants in multiclass endurance racing at the Nürburgring, Dumarey has occasionally finished ahead of drivers of significantly higher standing, including Max Verstappen and Sho Tsuboi, both multiple world champions in their respective disciplines who have made occasional appearances in endurance events.
