My pair is nowhere near that mileage, but have gone over some really rough terrain. First couple hundred meters on my touring bike always feel like I am riding a tank, like I am on a tracked vehicle - it's a really rough ride. But they are tough and strong. I did manage to get five punctures in less than two weeks (and then ripped the tire itself), but that was once, it's an outlier. I think I have one puncture per one thousand kilometers on average, which is not bad considering the terrain I often ride fully loaded.
Edit. Forgot to mention - my tires are Marathon Plus Tour. Marathon Plus are not as rough.
