For the sake of the sport, I would love for El Guerrouj's mile record to finally be broken, but there are a few things working against it.
1) The race is in the middle of the day. AccuWeather forecast says high of 84F with UV index of 10. 8mph winds from the north with 22mph gusts. 8mph isn't too bad, but I'd be concerned about those gusts.
2) Only one pacer listed on DL website - Abe Alvarado, who also paced the 2024 Bowerman Mile. For an attempt at a legendary record like 3:43.13 you should have at least 2 pacers, if not 3. I doubt Alvarado could get Nuguse to 1200m at WR pace. Ritz did say he wants the pace thru 800 to be 1:50. Alvarado could definitely do that, but probably could only get 100-200m further. That would leave Nuguse front-running the final 600-700m. Jakob front-ran the final 700 in 2023 to run 3:43.73, but he is a stronger athlete than Nuguse.
3) If Nuguse's priority is to win, then he won't risk going all out for a WR if it means a chance of losing. There will be a lot of strong guys right behind him - Hocker, Kessler, Habz, Laros, etc that could easily outkick him at the end.
All in all, I say the most likely outcome is a 3:44-3:45 winning time if conditions allow for it. If it's poor conditions, 3:46-3:47.
