Jakob isn´t running the 5000m in Tokyo. The 1500m / 5000m double isn´t doable (as ROJO has complained about several times; and I agree).
I'd assume he'll choose the 1500, too. I thought maybe it was like the women's side where the double is more doable. I think the way Jakob is running, it's hard to picture him not picking up silver in the 1500. More composure, making his last 50 among his best. Even in this race, he refrained from cutting off Ahmed or getting overly physical when he didn't have room and stayed patient. The talent/fitness gap between him and whoever is third figures to be pretty big in the 15.
