Just 15 minutes into the race, it was becoming apparent Tune's distance of 18.517 would come under threat in Brussels. After 5k favourites Sifan Hassan and Brigid Kosgei were 10 seconds clear of the Ethiopian's world record pace.
The world record pace was visually represented via the Wavelight, a moving green light signal which illustrated Tune's pace.
In addition to the guiding light, Hassan and Kosgei counted on a strong pacemaker in Sheila Chelangat. The Kenyan led for 38 minutes and did a fantastic job to lift Hassan and Kosgei to a pace 40 seconds clear of the world record.
Due to the coronavirus crisis the grandstands of the King Baudouin Stadium remained empty, but you wouldn't have known from listening to the race. For this year, real ambient and spectator sounds were mixed and played inside the stadium, giving the illusion of Brussels' typical packed grandstands, amplified by DJ Jonas' beats.
It seemed to lift Kosgei and Hassan to a stunning performance. The pair worked together until the last minute, when Hassan found another gear. Kosgei struggled to keep up with the Dutchwoman's scorching sprint and had to cede the win and the world record to Hassan.
Hassan kept on sprinting to set a stunning new benchmark of 18.930 km. Local Nina Lauwaert also beat the domestic Belgian record (Sigrid Vanden Bempt's 17.264 km in 2003) with a distance of 17.315.
