At the Diamond League meet Prefontaine Classic in Stanford, CA in June, Klosterhalfen finished second in the 3000 m with a new national record of 8:20.07, a nearly 10-second improvement on her own German national record set about two years prior. Her time ranked her the sixth-fastest woman over the distance in history. The run was won in a time of 8:18.49, a new European record by Sifan Hassan.[17][53] In August at the German Championships in Berlin, Klosterhalfen set a new national record in the 5000 m with a time of 14:26.76, a massive improvement on her former personal best of 14:51.38, putting her thirteenth on the world all-time list.

World Athletics Championships in Doha

At the 2019 World Athletics Championships in Doha, Klosterhalfen (L) lost only to Hellen Obiri (R) and Margaret Kipkemboi

On 5 October, Klosterhalfen won the 5000 m bronze medal at the Doha World Championships with a time of 14:28.43. The 2017 defending champion Obiri took the title in a time of 14:26.72, her Kenyan compatriot Margaret Kipkemboi became the runner-up with 14:27.49. It was the first World Championship 5000 m medal for a German woman.[62][63]

The termination of the Nike Oregon Project

On 1 October, the USADA banned the head coach of Klosterhalfen's training group Alberto Salazar, and Dr. Jeffery Brown, a colleague at the Oregon Project, for doping offences. These included using a WADA prohibited method, tampering with doping control methods and trafficking testosterone through a prohibited testing program.[64] The case against Salazar and Brown concerns a timeframe before Klosterhalfen was part of the project.[65] At the NOP Klosterhalfen was trained by Salazar's former assistant Pete Julian, who maintained on German television, "We know, we do everything right".[66] On 11 October, Nike decided to shut down its project.[67]

Regarding the closure of Nike's Oregon Project, Klosterhalfen stated: "It's a first and important decision, specially to protect the active athletes and what they have achieved. Since last week, their and my competition activities were put into offside due to this ongoing issue." (Translation from her statement in German).[68]

On 24 October, the Portland paper "The Oregonian" stated that Pete Julian likes to continue supervising seven athletes, formerly members of the Nike Oregon Project, among them Klosterhalfen. Furthermore, the article highlighted that no NOP athlete has ever failed a drug test nor been credibly accused of doping.[69] Klosterhalfen also confirmed that she will go on with training under the supervision of Julian.[70]

2020

edit

In January, Kosterhalfen competed in the first 1500 m race of the World Indoor Tour in Boston. She placed second with 4:04.38 in front of Ciara Mageean, who finished in a new Irish indoor record of 4:06.42. The race was won by Jessica Hull (also coached by Pete Julien) in 4:04.14, an improvement on the Oceanian indoor record by more than two seconds.[71][72] As the defending winner, Klosterhalfen placed second in the indoor mile run at the Millrose Games in February.[73] The event was won by Elinor Purrier (USA) with a new NACAC record of 4:16.85, the second-fastest time ever.[74] Klosterhalfen finished in 4:17.26, an almost 3 second improvement on her personal best and a new national record, the fourth-fastest time ever. She also bettered her 1500 m time en route with 3:59.87, another new German record.[75][76] Third placed finisher was Jemma Reekie with 4:17.88, a new national record and the 5th fastest time ever. DeBues-Stafford finished fourth in 4:19.73, a new national record and the eighth place on the all-time list.[77] The first four placed women also set new 1500 m national records en route.[78]

On 27 February, a 23-year-old Klosterhalfen set a European record in the indoor 5000 m event. The former area record was 14:47.35 set by Gabriela Szabo in 1999. Klosterhalfen won the competition at the Boston University Last Chance Invitational meet in 14:30.79, which placed her fourth in the world all-time ranking.[79] Her winning time marked a 45 seconds improvement on her previous personal best set in Boston in 2019.[80] Her final 200 m split was recorded with 31.6 seconds.[81][82] Klosterhalfen's split times:[83]

Distance interval Time Split

In July, Klosterhalfen set a new personal best to win the 1000 m at The Big Friendly 2 meet in Portland, OR in a time of 2:37.05.[84][85] In addition, she ran the 3000 m, but failed to finish.[86]

2021

edit

With her first 10,000 m race at the Trials of Miles Texas Qualifier in Austin, TX in February, Klosterhalfen set a new national record. She won in a time of 31:01.71, lapping all runners, breaking the former best of 31:03.62 set by Kathrin Ullrich in 1991. After the race, she complained about windy conditions.[87][88]

Her season was injury-plagued, including pelvic and back problems.[89] Despite this, at the delayed 2020 Tokyo Olympics in August, she competed in the 10,000 m event, finishing eighth out of 29 runners in 31:01.97.[2] The following month in home Trier, Klosterhalfen broke yet another national record, this time in the less common 2000 metres distance which had stood since 1985.[90]

edit

Klosterhalfen ended her indoor season prematurely because of a hamstring injury after a fall in January.[91]

In May, the 25-year-old set a European best in the rarely contested two miles in Eugene, Oregon.[92] After she got COVID-19 in June, she struggled to reach her form at the same venue during the World Championships the next month, and was eliminated in the heats of the 5000 m with 15:17.78.[2][93]

However, Klosterhalfen returned to fine form a month later at the European Championships on home soil in Munich, becoming the first German athlete to win the European Championship title at 5000 m.[91] She won decisively in this event with a time of 14:50.47, beating second-placed 2016 European 5000 m/10,000 m champion Yasemin Can by over six seconds.[94] It was the first double start at a major championships of her career as she also competed in the 10,000 m event three days earlier to finish fourth with a season's best.[95][93]

In October, on her debut at the distance, Klosterhalfen won the Valencia Half Marathon with the third-fastest time ever set by a European woman of 65:41, becoming the first female non-African winner of the event since 2003. She was 23 seconds short of the German record and 26 of the European record.[96][97] She competed at the European Cross Country Championships in Italy on 11 December, finishing a close second behind Karoline Grøvdal on a hilly and demanding 7.662 km course near Turin, leading Germany to their first ever team gold.[98] They clashed again on 31 December, this time over 5 km at the Cursa dels Nassos in Barcelona, and Klosterhalfen decisively came out on top, breaking the German record (Irina Mikitenko's 15:16) with a 14:52 performance behind only world record holder Ejgayehu Taye. Klosterhalfen was eight seconds short of the European record.[99]
