Oslo (three days after Stockholm this year) pretty much always sees a WR attempt in the 1609 - If Jakob Ingebrigtsen is back in shape by then he'll almost certainly take a crack at it (also, it's before Kerrs planed Project 222). The world stage marketing value for just being in that race, maybe even partially pacing it, is bigger than running something smaller back in the US. Also the "see and learn" factor for simply being in or near a staged WR attempt for someone who might to go after several WRs down the road himself...
What? Oslo pretty much always sees a mile WR attempt? I don’t think so.
