I'm trying to think about how or why Farah would say he was in France but post a picture of himself training in the track in Sabadell Spain, the town where the Aden raid was conducted. (if you don't know what i'm talking about read here http://www.letsrun.com/news/2016/06/jama-aden-doping-raid-update-might-raid-impact-mo-farah-dibabas-nike/ )
1) Innocent mistake. He was in France, had been in Spain previously before and just used a photo of himself training for his fans.
2) He wanted to hide the fact he was in Spain.
Those are the only explanations I can come up with.
I lean to #1.
As for #2, if he was trying to hide something there are few complicating factors. Why was he hiding and who would he be hiding from in 2014? Remember the tweet in question was from 2014 BEFORE any of Aden's athletes were busted for drugs.
Also if you were trying to hide that you were somewhere, could you really be that stupid to post a picture of yourself in that place and just call it somewhere else?
Am I missing anything here?
