They make a big deal about clamping down on doping in marathoning (check out the twitter feed of Tom Bedford - @Tom_Bedford), but they invite the following athletes, even though both are managed by Andrey Baranov, who has managed at least a half-dozen marathoners popped for doping over the past few years (most notably Shobukhova), almost all for blood manipulation.
Tatyana Arkhipova (Russia) 2:23:29
Tetyana Gamera-Shmyrko (Ukraine) 2:23:58
The website for Baranov's agency (Spartanik.com) is no longer up.
