Ken Goe breaks the news at the Oregonian:"Salazar said Rupp would continue to compete in the 10,000 through 2017, but would concentrate on marathon training."
Alberto also says, "You can be effective in the 10,000 while doing marathon training. There is precedent for that. But we won't be doing all that training for a kick. And he won't be running the 5,000 anymore. That is gone."

If Rupp wins USAs in the 10,000m this year it would be his amazing 9th straight USATF 10,000m title.
