It seems pretty clear cut to me. I'm not sure about the yellow flag when they had 300m to go, but with 150m to go, Gomes was running the Bowerman curve at the outside of lane 1. This trajectory gave room for Berra to establish a position on his inside shoulder. At this point, there was no interference. However, as Gomes admits in his block, he "did defend it when he felt him (Berra) on his inside." His method of defense was apparently to move into Berra's path, initiating contact. He should have been, and was, disqualified under USATF Rule 163.4.
What top master runners do you train with?
I watched the 1500m race live and then watched the replay at least 6 times.
While the whole race is not televised, the infraction appears to be from an incidental bump at 3:35 after the camera comes back from the high jump.
It is clear Berra runs in Gomes from behind which is clearly not Gomes' fault.
I agree that it depends on where the official was viewing this contact but it is ridiculous to throw out an athlete's when it's clearly not his action initiating the infraction!
The USATF should be ashamed of themselves.
Master's athletes work very hard (FYI, I am 32 but train with several world-class master's runners) and to DQ Mark because of such a ridiculous reason is so frustrating to the true fans of running/track.
Hopefully they come to their senses and give Gomes back his rightfully earned gold medal but in the meantime Berra must look at it and realize he got SMOKED in the final 200m which is Mark's M.O.
Anyone who knows Mark knows he is a world-class athlete, gentleman and has the utmost respect for his competition and the system. His classy response to this at fasterthanforty.com is evidence of this.
