When you fall in a highly competitive race, it’s over for you, particularly for sprinters. But even in long-distance foot races, falling not only places you way in the back of the pack, it becomes a psychological burden as you see your competitors fly by you.

And yet, Lasse Virén of Finland was not fazed. Virén was competing in the 10,000 meters in the Munich Olympics in 1972. It was the 12th lap of a 25-lap race when Virén’s leg hit the leg of Belgian runner, Emiel Puttemans, sending Virén tumbling to the cinder track. Famed Tunisian runner, Mohamed Gammoudi, also took a nasty spill tripping over Virén’s body. Virén, who fell behind by 20 meters, got up quickly, and re-started those long strides, getting back into the race after four laps.

In the last lap and a half, Virén stepped on the gas. But as this thrilling account from The Guardian relates, the man whose leg sent Virén to the ground 12 laps earlier was now breathing down Virén’s back.

At the bell, Virén raised the pace yet again, and Yifter was unable to respond. The air was suddenly too thick for his limbs. But Puttemans held on. The small Belgian, his face contorting with determination, closed the slight gap that Virén had opened up. ‘I believed I had a chance to win the gold medal,’ he said later. ‘Lasse was five metres ahead and I knew I must take my chance going into the final bend.’ So Puttemans moved on to Virén’s shoulder. The Finn accelerated. ‘As we came round to the home straight,’ Puttemans said, ‘I knew the gold was his.’ You could see Puttemans absorb this painful truth, but make an instantaneous reappraisal of ambition: he looked over his shoulder, to make sure Yifter was far enough behind him to be no threat, and settled for silver.

Virén not only won, but smashed the world record for the 10,000 meter race that had stood for seven years. Virén went on to win the 5,000 meter competition in the Munich Games, accomplishing the so-called “double”, which had been done only three times prior to Virén, and three times after him. Even more amazingly, Virén did it again, winning both the 5,000m and 10,000m races at the Montreal Games in 1976, the only “Double-Double” ever.
