In the Olympics, held in Melbourne later that year, Pirie ran against Kuts in the 10,000 metres and despite the tactics of Kuts, an aggressive front runner whose bursts of speed were particularly damaging to a long-striding runner like Pirie, he stayed with him into the last mile when every other competitor had dropped well back. Kuts surrendered the lead for a short while, then made a sprint which Pirie could not match and he dropped back. Kuts said that if Pirie had stayed with him on that last sprint he would have dropped out of the race. In the 5,000 metres Pirie took second place behind Kuts. Christopher Chataway, another British runner, had been selected on past performance. He had not competed at top level for more than a year as he was pursuing a media career. With Pirie and Derek Ibbotson, the third British runner, he was tracking Kuts and had moved ahead of them as they went into a bend. The Soviet runner was setting a much faster pace than Chataway had ever run. Chataway suffered an attack of stomach cramp which caused him to slow down, and as Pirie and Ibbotson came out of the bend they found that Kuts had opened a gap. Pirie and Ibbotson ran round Chataway but Kuts was able to exploit his advantage and won the race with a margin of 11 seconds, the largest ever for this event in Olympic history. For the latter stages of the race Pirie was running what was virtually a front race, as Kuts had broken away, but he was still strong enough to hold off a late challenge by Ibbotson.
The 1960 Rome Olympics were held in the height of the summer and Pirie and other leading British contestants asked to go on ahead of the main party, at their own expense, so that they might acclimatise to the heat. They were refused permission, on the grounds that "we travel as a team". Pirie and his fellow 5,000 metres contestants were eliminated in the heats, leaving Pirie's only chance of a gold medal the 10,000 metres held later in the games. Pirie followed the favourite, Murray Halberg of New Zealand. Halberg had won his major championships by making a tactical burst in the last mile and holding on to the lead – he had won the 5,000 metres at Rome by that tactic and Pirie's plan was to stay with him as he went forward. Halberg was probably suffering from his effort in the earlier race and as the race went on he failed to stay with the leaders. Pirie realised that he and Halberg had lost contact with them.
Post-Olympic career
For some years, after he had criticised them, sections of the press ran a campaign against Pirie particularly after the Olympics. In a radio interview with Eamonn Andrews soon after the games, the Australian runner Herb Elliott, referred to Pirie and Ibbotson who, having broken the world record for the mile in 1957, had never regained the same form and was not selected for Rome. Elliott said, "The British Press is the most vicious in the world. Their attitude to people like Pirie and Ibbotson is 'That bloke's on his way down, I'm going to kick him down and keep him there.'" In 1960 Pirie ran a sub-four minute mile in Dublin, clocking 3:59.9. Pirie won the British Orienteering Championships in its first two years, 1967 and 1968, and won the first edition of the JK Orienteering Festival. He also represented UK at the 1966 World Orienteering Championships, and again at the 1968 World Orienteering Championships. The 1998 edition of The Guinness Book of Records lists Gordon Pirie under the "Greatest Mileage" entry, stating that he had run a total distance of in 40 years to 1981.
''Running Fast and Injury Free''
In his book Running Fast and Injury Free Pirie advocates running with initially making ground contact with the midfoot, 3–5 steps per second to reduce fatigue, damage to feet, and wasting of energy on vertical movement of body. He also describes his collaboration with Adolf Dassler on designing running shoes with stronger toes for better durability with his advocated running style.
