The 2022 Sprint GrandNationals
The ‘Duffy’ is the most prestigious trophy in grassroots kart racing, and once a year the International Kart Federation holds its annual IKF Sprint GrandNationals. The names who call themselves Duffy winners are a who’s who of motorsports and the distinction of being an IKF national champion solidifies any racer’s legacy in the sport.
