There is a golden oldie theme running through the 2021 sports calendar and the trend could continue at the Indianapolis 500 on Sunday, when the 40-somethings, led by pole sitter Scott Dixon, will try to fend off the IndyCar youth movement.

The "Greatest Spectacle in Racing" is shaping up as a clash of generations and nowhere is that more evident than the front row of the grid.

Dixon, the 40-year-old father of three and six-time IndyCar series champion, will be lined up alongside two eager young guns in 21-year-old Colton Herta and Rinus VeeKay, who at 20 is the youngest front-row starter ever at the Indy 500.
