Caster Semenya will make a last-ditch attempt to qualify for the Olympic Games when she races over 5000 meters at a meet in Belgium this week.
The 30-year-old South African is banned from competing in any race from 400 meters to a mile after the sport's governing body World Athletics ruled in 2018 that to ensure fair competition, women with high natural testosterone levels must take medication to reduce them in order to compete in middle-distance races.
The double-Olympic 800 champion, who refuses to take any medication to alter her testosterone levels, has been left with the 5,000 as her best chance to go to the Tokyo Games but her efforts so far to finish inside the qualifying mark of 15:10.00 have failed.
