11. Fred Lorz
The 1904 men’s marathon ended in farce when Fred Lorz was crowned the winner, despite barely running half the race. Indeed, the opportunistic New Yorker had withdrawn from the event just nine miles in but re-entered at the 20-mile mark. He consequently reached the finish line 15 minutes ahead of the runner-up Thomas Hicks, before being caught out. What’s more, Hicks himself was later found to have used a performance-enhancing drug during the race, but unlike Lorz was allowed to keep his medal.
10. Hans-Gunnar Liljenwall
Half a century later the men’s modern pentathlon caused another Olympic scandal. In fact, the 1968 Mexico City Games were the first to test competitors for performance-enhancing drugs. Hans-Gunnar Liljenwall, who drank an “excessive quantity of alcohol” before the pistol shooting, subsequently became the first athlete to fall foul of the new laws. And although the Swede was forced to return his bronze, he can consider himself unlucky. Indeed, 14 of his competitors were also under the influence of tranquilizers that only later became banned.
