It looks like America has successfully exported marathon cheating and sleuthing to Africa.
Cheating is world-wide.
"Social media was on Monday (yesterday) abuzz with solidarity messages after a facebook post alleging that Brenda Makonyere was allegedly disqualified after winning the female 21km half marathon. Justice for Makonyere was the most popular comment as people sympathised with the young female athlete. Information availed by the organisers, however, suggest that the Makonyere did not complete the race but instead a male athlete crossed the line holding the electronic marathon tag."
