Cape Town - South African star athlete Wayde van Niekerk will run his first international 100m race in Velenje on Tuesday.
He will line-up with fellow South Africans Henricho Bruintjies and Emile Erasmus in Slovenia.
Van Niekerk has yet to win a 100m race this year after being stunned at the ASA Speed Series Meeting in Bloemfontein to teenager Gift Leotlela and losing to Rio Olympic finalist Akani Simbine at the SA national championships in Potchefstroom.
At the SA championships, Van Niekerk clocked a season best time of 10.22 to finish second behind Simbine.
However, Van Niekerk has yet to reach his personal best of 9.98, which he achieved in Bloemfontein last year.
Last year he become the first runner to break 10 seconds for 100m, 20 seconds for 200m and 44 seconds for 400m.
Van Niekerk has four meetings prior to the much anticipated London World Championships in August.
He will compete in the rarely-run 300m distance at the IAAF World Challenge meeting in Ostrava starting on Wednesday, June 28 - where he will attempt to break another Michael Johnson record after his 400m Rio Olympic triumph.
He'll then participate in the IAAF Diamond League meetings in Lausanne on July 6 and Monaco on July 21.
The 2017 World Championships will take place at London's Olympic Stadium from August 4-13.
