The reality for Rupp is: he is a father, he has a wife who wants him at home --not a Farah player--, he has kids he wants to spend time with. Running the 5k and 10k keep him on the track more, and in the grasp of Salazar. If he focuses--which I think is his plan--on the marathon he can do less track work, and do his long runs from closer to home. Less need to travel is another benefit of focusing on the marathon.
OK, clearly you do not know Rupp. He wants to be in the grasp of Salazar and he has no plan of his own apart from Alberto's plan. You have no clue.
The marathon will undoubtedly bring out the Respro mask, the only Rupp certified mask. The pollution is incredibly high in Rio and Rupp will be donning his trademark face wrap. When he wears it, we've come to loving call him Rabid Rupp.
If you haven't already seen them, there was a huge ad buy from an American company selling these as a build up to the Olympics. Respro is a UK outfit, but many American companies are now manufacturing and selling stateside (and in Rio).
