Two-time Formula 1 champion Fernando Alonso has indicated that Sunday's Spanish Grand Prix is likely to be his final race in Barcelona, as the event is set to become biennial from 2027. The Barcelona-Catalunya Grand Prix will not be staged again until 2028, leading the 44-year-old to tell reporters on Thursday: "It is probably going to be my last Barcelona race in Formula 1."While Alonso was quick to clarify he was not announcing his immediate retirement, the extended break until the next Barcelona event makes his involvement highly improbable. He revealed plans to consider his future in the coming months, weighing up whether to continue racing next season, especially given Aston Martin’s struggles to provide a competitive car.Alonso won the last of his two world titles 20 years ago (Getty)"I don’t have anything in mind, and after the summer I will take the decision to continue or not," the Spanish driver explained. "But Barcelona is not happening next year, and if I don’t know what I am doing next year it is near impossible to know what I will doing two years from now. Every race I go to could be my last."An icon of Spanish sport, Alonso secured world championships in 2005 and 2006, and is widely regarded as one of the series' finest drivers, despite years without a car to match his talent. His last F1 victory, his 32nd, came at this very track in Montmelo in 2013. Despite his current season yielding just one point, placing him 18th out of 22 drivers, tens of thousands of fans still flock to the Spanish race to support him.Reflecting on his career, Alonso expressed being "at peace" with his achievements, though he admitted the lack of competitiveness was challenging. "The hardest thing is to not win races and not be competitive," he said. "If (this season) is the last, it is not affecting me. I am at peace now with myself and my career. I achieved a lot more than I ever dreamt when I was a kid."
