Rodgers Kwemoi, Uganda, 3rd in the 10,000 at C.G. 10,000 is listed at 1.92/49kg on the C.G. website.
I think this has got to be a mistake, as no way could someone be that thin -were that the case, he would be literally skin and bones, with absolutely no muscle development whatsoever.
On another note, Jacob Kiplimo, also Uganda, who ran 27.30 in the same race has a birthdate of 14 November, 2000, making him just 17 years old. Another innacuracy.
Jake Robertson is also another BMI freak, listed at 1.88/62, and much touted Andy Vernon at 1.82/71. In normal life, Vernon would be considered a slim, fit looking individual, but next to some of the above figures, he looks almost like a body builder.
On the same subject, Mo Ahmed is another rake, at 1.82/56kg.
