Genzebe Dibaba

Genzebe won the junior women's title at both the 2008 and 2009 IAAF World Cross Country Championships and finished fifth in the same event in 2007. Dibaba became the second junior woman ever to win two junior cross country championships in a row. She also competed in IAAF Golden League meetings, including the Reebok Grand Prix and the Oslo Bislett Games. At the 2008 Bislett Games she recorded a personal best time of 15:02.41 in the 5000 metres, during the same race where her sister Tirunesh set a new world record. She did the same a year later in the same race, improving her personal best by more than five seconds.

She was the runner-up at the Great Edinburgh Cross Country in January 2011 behind Linet Masai. She placed ninth at the 2011 IAAF World Cross Country Championships two months later.

Genzebe opened 2013 on grass, winning the 3 km competition at the Great Edinburgh Cross Country, then took two indoor wins in Karlsruhe and Birmingham.

On February 1, 2014, in Karlsruhe, Germany, Genzebe ran 3:55.17 in the 1500 m indoor event, beating the previous indoor world record by over 3 seconds. This mark was the fastest 1500 m in the world, indoor or outdoor, since 1997.

During 2015 she changed shoe sponsor. In February in XL-Galan, Stockholm, she ran for Adidas, and in March in Carlsbad (CA, USA), she had her first official competition in Nike dress in the 5k-race, where she missed the world record by a small margin. The change of sponsor is associated with the change of manager – from Dutch Jos Hermens (Global Sports Communication) to Swedish Ulf Saletti. The manager change happened a few months before the sponsor change. Saletti is meeting director at Stockholm XL-Galan where she on 19 February 2015 repeated the achievement from the year before by setting a world record, now at 5000 meter with 14:18.86.

Genzebe won the women's 5000 m at the 2015 Prefontaine Classic in Eugene, Oregon, in a then-personal best time of 14:19.76. She then went on to win the 5000 m at the Diamond League Meet Areva in Paris on July 4 in a new personal best time of 14:15:41. This was her fifth 5000 meter run under 14:30. Only four days later, in Barcelona, she set a new African record for the 1500 m of 3:54.11 (video), virtually single-handedly running the fastest 1500 in the world in 18 years and the ninth fastest of all time. Six of the eight fastest times ahead of her occurred in two races at the 1993 Chinese National Games, where much of the running community believes the communist government was sponsoring a doping scheme in the days before serious drug testing was required. On 17 July 2015 in Monaco, Genzebe broke the 1500 m world record, which had previously been considered near-unbreakable, in a time of 3:50:07.

In February 2016, Genzebe competed in Stockholm's Globen Galan meeting. She ran the indoor mile in 4 minutes and 13.31 seconds, breaking Doina Melinte's 26-year-old world record of 4:17.14, which had been set in 1990. In April she pulled out of the Dubai Athletics President's Cup 10,000 m Olympic qualifier race due to an injury in her left foot. In a track meet in Barcelona on June 30, she failed to finish a 5000 m race due to an injury. She was removed from the track in a wheelchair.

In the 2016 Summer Olympics Dibaba run the women's 1500 m. In her heat (one out of 3) she won out of 14 runners in 4:10.61. In the semifinals (one out of 2) she was the fastest runner with 4.03.06. The final was won by Faith Chepngetich Kipyegon in a time of 4:08.92. Dibaba took the silver medal in a time of 4:10.27 and Jennifer Simpson placed third for a bronze medal with 4:10.53.

Genzebe broke the 2000 m indoor world record and also the absolute world record, because it lowered the outdoor mark as well, on 7 February 2017 in Sabadell (Spain). She ran the distance in 5:23.75, an improvement on the former indoor best by Gabriela Szabo from 1998 by 6 seconds. The outdoor world record was set by Sonia O'Sullivan with 5:25.36. An illness prevented her from running in her usual form at the 2017 World Athletics Championships, where she finished 12th in the 1500 metres. and later pulled off from the 5000 m event.

At the 2018 IAAF World Indoor Championships in Birmingham she became World Champion both in the 1500 m and in the 3000 m event.
