No shame in that but Jakob is turning 22 in a week and I see him limited in his turnover which means he will likely not run faster at 1500m than he has. Then he will probably continue to be a sub 13 and sub 27 man who occasionally wins a global championship for a few more years. This is his ceiling, so best possible personal bests would be 12:40 and 26:25. A pretty good career one might say.
