Well, it appears that any fellow runner in Rob's pictures has similar splits. I can't see where he slipped in or out of the race. It does look like he threw away a sub 3 run to do an interview. That, I don't get.
I think he exaggerated afterward, saying it was a 20 minute interview to make his time look better. His splits for 30K and 35K and the brief 2.2K at the end look fairly consistent. It's the 40K split that looks about 5-7 minutes long. So if he did an interview, probably no more than 5-7 minutes at most. And yeah, looks like he ruined his chance to get near sub-3. Will be interesting to see what he runs at Berlin and Chicago if he does so.
