27-29 October

> Algarve Classic Festival, Portimão, Portugal A great way to bring the curtain down on a season of retro racing, this festival includes the last outing of the year for the Historic Grand Prix Association’s eclectic multi-class format, featuring five decades of top-level single-seaters, from 1920s grand prix machinery to the multi-marque rivalries of the 1950s and the diminutive 1.5-litre screamers of the early 1960s.
