1:46/3:26.7/7:17/7:54/12:48, plus many-time Euro xc champ, makes for some pretty solid range right now. Who are you comparing him to? Augustine Choge ran 1:44/3:29/12:53ish, on up to marathon. Webb ran 1:43.8/3:30/3:46/13:10/27:34. Even El G had a 1:46 pr, with 3:26.0/3:43/7:23/12:50. Aouita ran 1:43/3:29/3:46.9/12:58/27:17. Jakob could stand to knock down that 800 pr or throw down a good 10000m but he's well on his way to best range for a 1500m runner considering the quality of his marks from 1500 through 5000m.
