On last Thursday Burgin celebrated his best personal record of under-20 with a record time of 1 minute 44.14 seconds.
On Wednesday, Keely Hodgkinson who is 19 years, won the women’s 800m.
The European Indoor champion had her lifetime best which is less than two minutes, 1:58:89, time for the first time.
This also comes under British under-20 record.
Burgin, who led from start to finish ahead of Dutchman Tony Van Diepen in second, fellow Brit Jake Wightman in third, and 2019 global silver medallist Amel Tuka in eighth, rapidly followed Hodgkinson’s stunning performance.
In the Czech Republic, Jessie Knight won the women’s 400m hurdles with a timing of 54.74 seconds.
Phil Normal ran the fastest time by a British athlete in 27 years to finish second in the 3,000m steeplechase with an Olympic qualifying time of 8:20.12.
Fred Kerley of the United States won the 100m in 9.96 seconds by finishing ahead of American Justin Gatlin (10.08) and Canadian Andre De Grasse (10.17).
Kerley, a global bronze medallist in the 400m in 2019, ran a 9.91 a month ago, his first time breaking the ten-second barrier.
Kerley competed again later in the competition over 200m, but he did not threaten to achieve the double, finishing second in 20.27, considerably behind compatriot Kenny Bednarek, who won in 19.93.
Sha’Carri Richardson, another American, appeared to have much left in the tank as she won the women’s 200m in 22.35 seconds.
