John Williamson is an experienced endurance athlete who finished the demanding Bull of Africa, a six-day non-stop adventure race in South Africa. He has also competed at a national level in the Landrover G4 Challenge and Southern Storm stage race. He describes himself as, "never turning down a challenge." This might explain how he is able to manage and own seven quick-service restaurants in South Africa. John volunteered at the Atacama Crossing 2011 and RacingThePlanet: Nepal 2011 before completing races as a competitor at RacingThePlanet: Jordan 2012, Iceland 2013, Sri Lanka 2016 and the Gobi March (China) 2017. He also volunteered at the Sahara Race (Namibia) 2016. John is now returning for his fourth times on the volunteers team at the Sahara Race (Namibia) 2018.
