Chepkoech has already enjoyed success this year, most notably when achieving a 5k (road) world record in Monaco (14:43) and an indoor personal best for 3000m (8:31.72), both in February. Her 3000m SC world record, also achieved in Monaco (2018), is an incredible 8:44.32.
Coburn, Olympic bronze medallist in Rio and 2017 world champion, has a 3000m SC best of 9:02.35 from the 2019 World Championships. She recorded an indoor personal best over 3000m this year clocking 8:39.19 in New York, and ran 15:24.76 for 5000m in February – her fastest time ever over the distance. More recently, she clocked 4:04.28, just outside her PB, to finish fourth at the Track Meet in California.
Krause is the German national record holder in the 3000m SC courtesy of her World Championships bronze medal-winning performance in 2019 (9:03.30). She raced extensively throughout the 2021 indoor season and opened her outdoor season with a 2:05.76 800m in Germany on 21 May. She will compete in her first 3000m SC of the year in Doha as she prepares for her third Olympic Games this summer.
Chepkoech, who finished third over 3000m in the 2020 Wanda Doha Diamond League, said: "I'm looking forward to competing in Doha. It's the place where I became World Champion. 2021 is a special year with the Olympics coming up and I would like to start my outdoor season in a nice way."
The 2021 Wanda Diamond League comprises 14 meetings and started with Gateshead (which replaced Rabat as the first host city on this year’s circuit) on Sunday 23 May. A single final will be held across two days in Zurich at the end of the season (8/9 September). Each meeting will be broadcast globally in a live two-hour programme.
The 2021 calendar remains subject to change depending on the global health situation in the coming months.
