In a USATF interview he declares he is running both marathon and at least 10k and possibly 5k.
The rest of the marathoners entered just collectively shat themselves
I at least see him starting the Marathon in Rio unless he decides to try again for the 10/5 double. There are 8 days between the 10000 and the Marahton, which might be enough to recharge a bit. If he is to go for that double, do not expect him to race at all for 4-6 weeks prior to the 10000m
He says his focus is still on the 10K. Almost sounds like he's running the trials so that he has the marathon as a backup.
It is a very real possibility, in my view, that Rupp will qualify, take a spot on the team, but DNS the marathon in Rio. That would a be real shame.
