I used google translate on this page and the text reads like this:
Winner of the Berlin Marathon admits dopingSportshow 03.08.2017 | 01:09 Min. | Available until 03.08.2018 | The firstThat doping in the Ethiopian athletics reaches to the absolute top, show ARD searches with hidden camera. A top athlete in the country admits to a decoy to have doped. Brisant: The person is still active, is among the best in the world and has already won the Berlin Marathon.
Haile and Kenenisa are the only Ethiopian men to have ever won Berlin and since Haile is not still active that leaves only Kenenisa.
A sad thing indeed if that is true, and I hope it is not. And I don't understand why would Kenenisa ever admit that, even to a decoy, even if he didn't know he was been filmed?
