Ok Mr Wrong!!, we get it, your sarcasm wins the day, now go take a nap.
As for this WR, lets just say the other WR's set this week pale in comparison and he could probably break the 3k and 5k indoor in his sleep.
I'm certain the US elites are shaken by this. Its monumental. Sub 40min 15k??
Is he on drugs? I dont think so personally, I think the shoes are a huge part of this, you get to train with less tired legs and you get to race in carbon plates, win win.
If there was an athlete to replace the talent of the late Kelvin Kiptum this is the man. Barring injury he will no doubt break the 2hr marathon barrier.
‘I suspect the drafting helped a lot more than the bicarb. He was close behind the lead car for most of it’
True. I doubt he would have broken 57.00 without the draft, maybe 57.30. Still a world class performance but World Athletics should add some rules on this. If the driver is not experienced enough to understand what the effect is, a judge on a motorbike could send him or her up the road. Happenes all the time in cycling.

Simply prodigious, first outkicked Jakob in Zurich 3000m in 2021 running 7:27 after Jakob won the 1500m, and proceeded to struggle somewhat at major championships on track surfaces but dominated the cross country like a boss!! His lack of gold and silver medals on the track for somebody with even better top end speed than Jakob albeit in only 1 race shows us this sort of space-time progression is clean and doping free. He would still be ranked as clean even if he went on to win 5k and 10k doubles at major champs for the simple reason he is an XC masterclass both in his teenage and adult career. Was also a teenage prodigy at 15 winning Kampala and had the right effortless and fluid biomechanics to boot. Also as an Ugandan training in Kapchorwa we all know how backward this area is with lots of fertile land and a great lack of telecommunications services which is great for producing durable distance running GOATS!!
I accept and induct Jacob Kiplimo in the hall of fame for world records which includes Bekele who still holds the indoor 5000m WR or 12:49 as of today in 2025.

Amen sweetheart, today is the best day of my life to see one of the future goats I foretell actually realise my foretelling just like that by running 56! He now can do double 59s easily which would put him in 1:58 range hopefully for the FM!
probably the most impressive distance WR at the moment..
Amen bro!! I fete every clean impressive human feat with the letter AMEN!! I don’t think he will be a good marathoner as I always believed the FM isn’t just linearly twice the HM, it’s rather physiologically 5 times the HM due to non linear thermal degradation!
This is what you must expect from a world legit strength champion aka world cross country champion double times and almost triple if we count he almost won 2019 with that insane hill every loop. Kiplimo’s progression is exactly how you will find a clean athlete running and at the correct age. Kipchoge is different as he was of the wrong age and had way too many unusual successes.
Kiplimo has been running fast for a long time but, man, WRs are just getting harder & harder for me to get excited about personally. 56:42 is sub-27min 10ks back to back plus another 1k+ at that pace.
He didn't come out of nowhere tho. 57:xx 2020, 2021, and 2022. Ran NYC Half in 2023 & won on a gross day that was cold + had a headwind, beating Cheptegei by ~40s in 2nd. He also ran ~58-flat in 2024. Perfect weather today. Maybe the next iteration of shoes are better. Just feel like smashing the half isn't really supposed to be a thing at this point versus taking off a few seconds here & there. Feels wild to me that Mantz is 2:30 behind this effort. When Ryan Hall ran 59:43, the WR was 59:07. It improved to 58:33 later that same year but he was within 36s when he ran it.
I suspect the drafting helped a lot more than the bicarb. He was close behind the lead car for most of it.
There have been some studies on drafting, for running in formations (sub 2h attempt etc). Long story short: maximum advantage was calculated 154s on the marathon distance (2.34 min). The draft of a car just a few meters in front of the runner should be even higher than an ideal formation (by the way, the role of the huge timing device on top of the lead car at the sub2 event has been noted at the time). So the effect is real and should be taken seriously and avoided for fair comparisons between record times.
Right now there are rules for labelled road running events concerning the lead car. As: the car should not obstruct the view for the runners on the shortest line for the course. But nothing on the minimum distance between the lead car and the leading runners.
