Apparently, while doing all that, Farah found time to take an ice bath. eBay user rklassman had the good entrepreneurial sense to snap up water bottle full of what was left over, or pretend he did:
Buy at own risk.This is only water that I hope to have been scooped out of Mo Farah's ice bath and placed into this water bottle after his 2012 olympic win. Impossible to authenticate buy at own risk. Their was ice in the bottle but it has melted. My apologizes :(
The water bottle is all yours for only $1000. Luckily, the end of the bidding is 9 days away, so you have time to apply for a loan.
