I’m with you. Every time I’ve taken splits from the video for El G’s world record, it is 39.9-40.0 for last 300 (and 53.4-53.6 for last 400). It’s a weird idea that somehow 2:46.34 is an unassailable split time for 1200 meters. I keep getting 2:46.0-2:46.1. It’s the final time we can have confidence in, not the 1200 split.
In his 2001 3:26.12, El Guerrouj appears to have closed in about 39.9 as well, where he was pushed to the line by Lagat.
Relating it back to the point of the thread, part of the argument against Ingebrigtsen challenging the record is the large gap between his closing ability and El Guerrouj’s. But the gap is not as big as those “official” splits make it appear. The reality is that Hicham’s 1500s were imperfectly split, and if Jakob (or anyone) will challenge the record, it will be with better pacing, giving up a second or more the first 400, then clawing that back (and probably a couple tenths more) the next two laps. While 39.9 off that pace is excellent, and it seems unlikely that even Hocker could exceed that by much, if at all, off a 2 second faster pace than Paris, a peak form Jakob might nip the record getting through 1200 in a well paced 2:45.8
The stadium altitude is favorable, but the predicted temperature seems too cool for the racers to remain warmed up enough, by the time the gun goes off, to run a fast first lap comfortably. I predict it looks a bit like Lausanne, never on pace, with Jakob winning near 3:27.0 and a bit of a rebound from Hocker…
