Goodwood Festival of Speed might seem impossible to follow, but the ever-expanding Silverstone Classic (Saturday 21 July and Sunday 22 July) appears to be managing it. There will be a total of 24 races. We can’t cover them all, but these are some of the highlights.One of the most famous races in British motor sport – the Daily Express International Trophy – is being revived. The prize will be awarded later this month to the aggregate winner of the two Grand Prix Masters races. First run in 1949, the roster of winners reads like a who’s who of motor sport history. Alberto Ascari won the inaugural event for Ferrari and subsequent victors include Mike Hawthorn, Stirling Moss, Jack Brabham, Graham Hill, Jim Clark, Jackie Stewart, Emerson Fittipaldi, James Hunt and Niki Lauda. Keke Rosberg won the final contest held for Formula 1 cars in 1978.
