Jared Tallent

Tallent crossed the line second in the London 2012 50km behind Russia's Sergey Kirdyapkin, and nearly four years later Kirdyapkin's result was annulled for doping and Tallent was awarded the gold, receiving it at a ceremony in Melbourne in 2016. With further Olympic medals in Beijing and Rio, he was one of the most consistent long-distance walkers of his era, and an outspoken campaigner against the doping that cost him his moment on the podium.
