He started out playing basketball and football, where his football coach, Adriano Bertazzi, took notice of his speed and suggested that Jacobs try sprinting.[3]
When Jacobs was ten, he began competing in athletics. He preferred sprinting until he discovered the long jump in 2011.
Personal life
Jacobs lives in Rome with his wife, Nicole Daza, and their two children.[11][13] Jacobs has another son, born from a previous relationship when Jacobs was nineteen.[14]
Although Jacobs was born in the United States, he identifies as Italian.[15]
Jacobs had been estranged from his father since he was an infant; however, in 2020, he reestablished a relationship with him at the suggestion of his mental coach. He said that reconciling with his father gave him the motivation and peace of mind he needed to focus on winning in the Olympics.[16][17]
Career
Long jump
In 2016, Jacobs won the Italian Athletics Championships in long jump. With a personal best of 8.07 meters, he ranked tenth on the IAAF (now World Athletics) world-leading list at the end of the 2017 indoor season.[18]
At the 2016 Italian U23 Championships, he jumped 8.48 meters, the best performance ever for an Italian, although this result was not recognized as a national record due to a 2.8 m/s tailwind, which was 0.8 m/s above the allowable maximum for any record performance.[19][20]
Jacobs did not participate in the 2016 Summer Olympics due to a hamstring injury.[21]
Sprinting
In 2019, Jacobs decided to focus his efforts exclusively on sprinting, citing frequent injuries while long jumping among the reasons for this switch.[3]
In July 2019, Jacobs lowered his 100 metres personal best to 10.03 seconds, making him the third-fastest Italian in history.[3]
On 13 May 2021, in Savona, Italy, Jacobs set the Italian record in the 100 metres with a time of 9.95 seconds, becoming the 150th person in history and the second Italian, after Filippo Tortu, to break the 10-second barrier.[22] On 26 June 2021, into a headwind of −1.0 m/s in Rovereto, he broke the Italian championship record with a time of 10.01 seconds, winning his fourth national title in a row.
2020 Olympics
Jacobs won his first 100 metres heat at the 2020 Tokyo Olympics in 9.94 seconds, improving his own Italian record by 0.01. In the semi-final, he was third with a time of 9.84 seconds, setting a new European record and qualifying for the final with the third overall fastest time. He is the first Italian to ever reach an Olympic 100m final.[23][24]
His effort broke the European record he set in the semi-final earlier that day, recording the fastest time ever run by an athlete that is neither American nor Jamaican. Due to this performance, Jacobs is tied with Steve Mullings as the 10th fastest man of all time.[26][27] Jacobs was not favored to win the race, with bookmakers giving him a three percent chance of winning.[28][29]
Jacobs later won a second gold medal in the 4×100 metres as part of the Italian relay team, along with Lorenzo Patta, Fausto Desalu and Filippo Tortu. It was the first time Italy had ever won this event, and also the first time Italy had earned a medal in the event in 73 years.[30][31] Jacobs ran the team's second leg (split time: 8.925), contributing to its total run time of 37.50 seconds, setting a new Italian record.[32][33]
Jacobs ended his season shortly after the Olympics, citing fatigue, and cancelling two upcoming Diamond League appearances.[35]
After the Games, it was reported that Giacomo Spazzini, who had worked as Jacobs' nutritionist, was involved in a steroid investigation in Italy. In response, Jacobs' agent stated that the athlete had cut ties with Spazzini several months before the Olympics.[36] In 2022, the investigators established that Spazzini himself was a victim of collaboration with a person who turned out to be a fake doctor: the biologist Antonio Armiento who negotiated a sentence of 1 year and 11 months and 20 days for falsely declaring he was a doctor and free prescription of antihistamines and diuretics.[37]
2021/2022 indoor season
Jacobs returned to competition in February 2022, winning the 60 m race at the ISTAF Indoor in Berlin with a time of 6.51.[38] In subsequent races, which included winning the national 60 m indoor title, he lowered his season best to 6.49,[39] arriving at the world indoor championships in Belgrade with the 5th fastest time in the season. In his semi-final he equalled the world leading time of 6.45,[40] held by pre-championship favorite and world record holder Christian Coleman and Bahamian sprinter Terrence Jones, setting a new national record. In the final he edged Coleman by 3 thousands of a second setting a new European record of 6.41,[41] winning the gold medal and becoming the 4th fastest man in history on such distance.
2022 outdoor season
Jacobs was supposed to start his outdoor season competing in the 100 metres at the 2022 Kip Keino Classic in Nairobi, Kenya, however he missed his debut after being hospitalised for a gastrointestinal infection.[42] He officially opened his outdoor season with a time of 10.04, winning an international meet in Savona,[43] after changing his original plan of competing in the 200 metres.[44] Having sustained a slight injury to his biceps femoris, he took the decision to withdraw from three Diamond League meets which were on his calendar.[45]
