He's not a 13:20 runner. He ran 7:34 - 13:12 - sub 28. That's quite a big difference. And he never ran 1:01. He ran 1:02low. I hate to say it as I really wish everybody well - but I feel like he gets worse with longer distance (7:34 is far better than 1:02:xx in my book).
2:09:32. I would argue that lines up perfectly with his other PRs. But to do that in his first Marathon is impressive.
