I know virtual races aren't a matter of great interest here, but I looked at the virtual results from London (

), and I noticed that the men's "winner" is a guy previously busted for cheating:

Furthermore, the women's winner is listed as 2:25:14 as a 45-49 year old. The only issue with that? The 45+ world record is 2:28:34 by a woman who was an Olympian at age 44. Does London verify this stuff whatsoever?
