There are marshalls all over the race course at international events like this whose sole purpose is to disqualify athletes that breach any rules. If he had broken any rules he would have been disqualified before the race even ended, or at least the moment he finished.
How could a marshal who only saw him pass for a few seconds, make that judgement?
Drafting the lead car could be a huge deal. Drafting works.
But how do we explain the two Spanish guys who went 2-3? That is what is the weirdest thing to me. Kiplimo is ultra-elite, so I get it. But Josep Sola Benitez running 57:38 and Ivan Serrano Hernandez breaking 58:00? What the heck? What about a total unknown running 58:55? That is faster than the US record!
Results:
Jacob Kiplimo (UGA) – 56:42 World Record (no words for this)
Josep Solà Benítez – 57:38 (SMH and/or stunned)
Ivan Serrano Hernandez – 57:59 (Never heard of this guy; have you?)
Zulnio Tarakanantyo Yudha – 58:31 (Huh? WTH?)
Geoffrey Kipsang Kamworor –58:44 (okay, this finally makes sense)
Daniel Delgado Cañaveral – 58:55 (has he run professionally before this race?)
p.s. Zulnio Tarakanantyo Yudha doesn't even give me a google result. Those names have, it seems, never existed in that order before today. Is this even a real person?

Umm ever heard of headsets for communication? Marshall’s are in contact with each other all over the course.

Computational studies were done for Breaking2. The lead car makes almost no difference, even with a comically gigantic clock on top of it. If Kiplimo drafted as close to the car as Kipchoge did, for the ENTIRE race, the benefit would be...about 13 seconds total. Having a pacer immediately in front of you is over 10x more beneifical.

IMHO, to get some benefit one should be much closer to the car than Kiplimo was. In the cycling sport there was a kind of race on track when a motorbike leads a cyclist (don't know if it is still on). And the latter is not more that 1.5 m behind for speeds about 60+ km/h. If this close contact is lost, he immediately "hits a wall". And for speeds like 20+ km/h this distance should be less.
This could be easily modelled/simulated numerically nowadays. Are there any experts in aerodynamics here outfitted with appropriate software toolkits?
Agreed, way too far back to get a benefit from the car. You could easily test it with a bicycle behind a car at that pace. You could even feel turbulence

The biking speed speed record behind a car is 268 km/hour so drafting plays a huge role if you are close enough.
So many people making comments when they have no idea about aerodynamics. Take Ironman competitions, there is a 12 meter draft-limit, and EVEN then, they are biking in trains because of the advantage. Even at the lower speed of running, drafting a CAR with a clock at the top will have a significant effect. Noone is arguing he would run 90 minutes without the car, just maybe 1% slower.
I dont see him being disqualified, as its not Kiplimos fault, but the organizers have really not being doing their job by letting this happen.
I didn't watch it yet, but if he did, it's certainly not his fault unless he bribed the driver or organizers. It's the responsibility of the lead/camera cars (or bikes) to stay far enough in front and those vehicles certainly have enough power to do so. It's not the runner's job.
Disqualification of a runner due to an illegal course isn’t about whether it’s the runner’s “fault.”

If a course is found to be short or downhill, the time doesn’t stand. It’s not about “fault.”

Excellent article. Maybe the car provided ~10 second benefit which is much smaller benefit than what he would have gotten from 10 km of traditional pacing (1 minute benefit) right behind another runner.
I watched most of the race. At times he was getting closer to the car, but in the 2nd half of the race the gap was too big to be getting any wind-draft effect. I don't think it played a role in this run. Kiplimo was on fire and the only thing he had to chase was the pace car.
I disagree. He was less than 2 seconds behind the lead car during most of the second half.
At the pace he was running 2ish seconds is around 16m (35ft) back.
He was not that close to get that help, contrary it looks to me that he could gotten affected by the distance from him and the car. In order to get the benefits of wind protection you gotta be very close to the car otherwise you get more wind turbulence. Don’t believe me get in a road bike with a group of guys much stronger than you and try drafting properly (inches away from the guy in from of you) and then get away 10-15 meters.
according to the race director, a race marshal was there on a scooter alongside the lead car and kiplimo .
On some occasions he was definitely closer to the lead car that I have seen in most races, but I think it was only enough to get a small advantage during maybe 25% of the time. as said above when cyclists use (sometimes illegally) the team car to join the peloton they sit really close behind the car otherwise there is not much benefit or even a negative impact.
One thing is sure, he would have enjoyed a much bigger performance boost if he was tucked in behind a pacer for 15kms
The car is like the best pacer ever. Something big to chase after the whole race that will generate some draft and shield you from headwinds. It should be at least 3-4 seconds up the road, here it was well within 2 seconds most of the time.
