The 2012 Summer Olympics marked Emanuele Guidi's first appearance at the Olympic Games at the age of 42. He qualified for the men's individual competition after receiving a wild card from the Tripartite Commission. The archery events at the 2012 London Games were held at the Lord's Cricket Ground. Guidi competed on 27 July in the ranking round, finishing 64th and last of all competitors with 589 points. He scored 110 points less than the leading competitor, Im Dong-Hyun of South Korea. Guidi competed against Im, the second-placed ranked archer in the world, in the Round of 64 three days later. Guidi made a good start but was unable to put Im under pressure throughout the contest and the latter took all three sets of the match to advance into the next round of the contest. After the competition, Guidi said to Reuters, "I am still shaking. Did you see me shaking on the shooting line? I had nothing to lose today. My first objective was being here and I am. I just hope I did not make such a bad performance."
