For kicks I ran this scenario through my TrackBot AI previewer. It's basing this prediction off each athlete at the year of their last 1500m Olympic title, not earlier or later. It takes their last two years of results from World Athletics and some basic details like their age into account. This is what it said:
Predicted Finish and Times:
Jakob Ingebrigtsen (NOR) - 3:28.50
Hicham el Guerrouj (MAR) - 3:29.00
Taoufik Makhloufi (ALG) - 3:29.50
Matthew Centrowitz (USA) - 3:30.00
Sebastian Coe (GBR) - 3:30.50
Asbel Kiprop (KEN) - 3:31.00
Noah Ngeny (KEN) - 3:31.50
John Walker (NZL) - 3:32.00
Noureddine Morceli (ALG) - 3:32.50
Peter Rono (KEN) - 3:33.00
Fermín Cacho (ESP) - 3:34.00
Details and reasoning can be seen on the site (still working on the coherence of this):
