2013: Borlée third at 400 meters
The KBC Nacht (KBC Night) landed a few personal best performances for several Belgian athletes, but no one managed to reel in a ticket for the World championships.
Jonathan Borlée claimed third in the 400 meter. Albert Rop concluded his 5000 meter well. In the B-series of the 1500 meter race favourite Jeff See fell. Matt Elliott claimed victory in 3:37.07, a personal best. Kim Ruell claimed third in 3:37.62, also a personal best.
Ryan Brathwaite
, the 2009 world champion, was disqualified in the 110m hurdles after a false start. Andrew Riley won in 13:39. Adrien Deghelt was sixth and Damien Broothaerts seventh but neither made the threshold for the World Championships in Moscow.

In the 100m hurdles Sara Aerts and Eline Berings aimed at a ticket themselves, eyeing the limit of 12:94. Aerts claimed fourth at 13:02. Anne Zagrée, who already secured her ticket, managed 13:07. Bering claimed eighth. Kristi Castlin won the event in 12:77.

Abraham Rotich could not win the 800 meter for a second consecutive year. After a first lap in 48:6, he was passed by Abdulaziz Mohammed (1:44.36). Rotich claimed fourth. Jan Van Den Broeck claimed fifth with a personal best, but his performance was not good enough for a ticket to Moscow.

Abdalaati Iguider, bronze medal at the Olympic Games in London, got most attention for the 1500 meters. Still, he was outrun in the final straight by Jordan McNamara. The American won in 3:35.29. Jeroen D'Beware claimed seventh in 3:37.25, Ali Hamdi fifteenth in 3:41.38.

David Verburg won the 400 meters in 45:43. Child Butler was second, Jonathan Borlée third in 45:62. Lalonde Gordon, bronze at the London Olympics, came in only fourth.

Hans Van Alphen made his comeback. The decathlete took part in the shot put. On his last attempt he threw 14m78, his best effort of the evening.

Albert Rop was very fast in the concluding 5000 meters. The athlete from Bahrain finished in 12:59.42, his first ever performance under 13 minutes. Bashir Abdi, who already had made the Worlds threshold in the 10,000 meters, could not repeat his performance and finished behind Abdelhadi El Hachimi (18th in 13:28:05, a personal best).
