Zimbabwean runner Isaac Mpofu on Sunday forfeited R50 000 in prize money during the Durban International Marathon for having one licence number.
The 42.2km run was won by Mpofu in 2:10:04 but there was drama as he was about to be declared the winner.
Mpofu’s World Championships qualification hangs in the balance after the disqualification.
The qualifying time for the men’s World Athletics Championships qualification that is due to take place from July 15 to July 24 in Oregon, United States, is 2 hours 11 minutes 30 seconds.
Mpofu had one licence number which was placed in front his vest and nothing on the back of his shirt at the finish line.
According to Athletics South Africa (ASA), Mpofu had to be disqualified and forfeit the R50 000 prize money, as per the rules.
ASA said the rules are clear that the participants of the Durban International Marathon had to have two license numbers on the day.
South African runner Tumelo Motlagale was declared the winner after he came in second behind Mpofu having clocked 2:11:15.
