John Trevor Blokdyk (30 November 1935 – 19 March 1995) and Formula One driver who participated in two World Championship Grands Prix, although qualifying for only one. He earned six caps for the South Africa national speedway team.

Career

Blokdyk rode in speedway in Britain in the late 1950s and early 1960s for Poole Pirates and Ipswich Witches. In 1962, he signed for Leicester Hunters but after one match for the team announced that he was quitting speedway to concentrate on motor racing. He was more successful at his next race, the Natal Grand Prix at Westmead, where he finished eighth.

Coventry Bees attempted to sign him from Ipswich Witches in June 1962 but failed to contact him to seal the transfer.

In late 1962, Blokdyk went to Europe to pursue a career in Formula Junior and was soon a front-runner, until he ran short of finances and returned to South Africa.

Blokdyk continued in the South African Formula One Championship in 1964 and then moved back to Europe and drove in Formula 3, scoring some good results, including a win at Magny-Cours and Nogaro.
