The Wanda Diamond League season is set to begin in just under two months time in Rabat, so could 2021 prove to be a record-breaking year for athletics most prestigious season-long competition?
Despite major limitations due to the coronavirus pandemic, 2020 saw four Diamond League records tumble in the traditional Diamond Disciplines, as athletes such as Mondo Duplantis and Karsten Warholm achieved new levels of greatness on the WDL circuit.
Many of the Diamond League records which currently stand were set in the last few years, but there remain a handful of marks which have proven more difficult to beat.
Here's a look back at the longest-standing Diamond League records.*
Brittney Reese - Women's Long Jump
7.25 - Doha 2013
A seven-time world champion and Olympic gold medallist, US superstar Brittney Reese is also the Diamond League record holder in the women's long jump thanks to a 7.25m leap in Doha eight years ago. The best jump in the world for nine years at the time, the closest anyone has got since on the circuit is Germany's Malaika Mihambo, who cleared 7.07m on her way to the Diamond Trophy in 2019.
Aries Merritt - Men's 110m Hurdles
12.80 - Brussels 2012
The first of many world records to have been broken in the Diamond League, Aries Merritt's 12.80 in Brussels in 2012 is still yet to be beaten either on or off the WDL circuit. An 11-time meeting winner, 2012 remains the only year that Merritt managed to get his hands on the Diamond Trophy.
Yohan Blake - Men's 100m
9.69 - Lausanne 2012
It takes quite something to put Usain Bolt in the shade, but fellow Jamaican Yohan Blake managed it at Athletissima in 2012 when he set a new Diamond League record of 9.69 in the 100m. It was all the more impressive as he admitted to being ill for most of the week, and even Bolt was never able to beat the mark at a Diamond League meeting.
David Rudisha - Men's 800m
1:41.54 - Paris 2012
The seventh-fastest performance of all-time back then, David Rudisha's world-leading and Diamond League record-breaking performance in Paris in 2012 remains a series best in the 800m nearly a decade on. Though he didn't go on to win a third Diamond Trophy that year, the Kenyan's performance was the perfect set-up for his world-record breaking Olympic gold in London just weeks later. The only other man to go below 1:42 in the Diamond League is Nijel Amos, who will be out to claim a record fourth title in 2021.
Valerie Adams - Women's Shot Put
21.03 - Rome 2012
While Chinese star Lijiao Gong has dominated the women's shot put in recent weeks, New Zealand legend Valerie Adams remains the Diamond League record holder with her 21.03m effort in Rome in 2012. Gong needs another two Diamond Trophies to match Adams' impressive five titles, and she will need to add more than 70cm to her Diamond League best so far (a title winning 20.31 in Zurich in 2019) in order to take the record.
Yohan Blake - Men's 200m
19.26 - Brussels 2011
Blake makes a second appearance in this list thanks to his 19.26 in the 200m in Brussels in 2011. This record, however, may be in more danger than his 100m mark, as US star Noah Lyles continues to strengthen his stranglehold on the 200m. Lyles' 19.50 in Lausanne in 2019 has put him within a whisker of setting a new Diamond League record, and who would bet against him being even better in the next few seasons?
Christina Obergföll - Women's Javelin
69.57 - Zurich 2011
One of the most hotly contested disciplines over a decade of Diamond League history, the women's javelin is still yet to see a bigger throw than Christina Obergföll's title-winning 69.57 in Zurich in 2011. Can China's Lyu Huihui, who will be out to defend her 2019 title this year, attack the record in 2021?
Kaliese Spencer - Women's 400m Hurdles
52.79 - London 2011
The second-oldest Diamond League record belongs to Kaliese Spencer in the women's 400m hurdles. Her 52.79 in London was the eighth-fastest of all time in 2011, and remains the fastest ever on the Diamond League circuit - though only, it must be said, by a whisker. Among those breathing down her neck in the all-time WDL list is reigning champion Sydney McLaughlin, who clocked 52.85 to win her first Diamond Trophy in Zurich two years ago.
Carmelita Jeter - Women's 100m
10.70 - Eugene 2011
The award for the most tenacious Diamond League record goes to Carmelita Jeter, who clocked 10.70 in the women's 100m with a just-legal wind-reading of +2.0 at the start of the 2011 season. Ten years on, the mark is still yet to be broken, though Jeter's mark of three Diamond Trophies has since been beaten by sprinters such as Shelly-Ann Fraser-Pryce and Allyson Felix. With the likes of Fraser-Pryce, Dina Asher-Smith and Elaine Thompson hoping to claim the Diamond Trophy this year, could 2021 be the year that Jeter's record finally falls?
