In 2008, Mark Webber was riding his mountain bike as part of the ‘Mark Webber Pure Tasmania Challenge’ charity event when he collided with an oncoming car in a freak accident. That left him with a badly broken leg which required surgery and put him out of action for several weeks, causing him to miss an end of season test with Red Bull.
He was back testing in February the following year and despite his leg having not yet fully healed, raced in the entire 2009 season. He didn’t have the final metal rod removed from his leg until the start of the 2013 season - ‘Aussie Grit’ indeed!
Jackie Pretorius (born 1934) raced in the South African F1 championship in the 1960s and 1970s, during which time he also entered four grands prix - all of which were in South Africa. He failed to qualify in 1965, was unclassified in 1968, and retired in 1971 and 1973.
