What, specifically, made this attempt (and the Breaking2 attempt) not eligible for a world record? Pacemakers are allowed under IAAF criteria: https://en.wikipedia.org/wiki/List_of_world_records_in_athle... https://en.wikipedia.org/wiki/Marathon_world_record_progress...

Also, per the linked Wiki reference “and meet other criteria that rule out artificially fast times produced on courses aided by downhill slope or tailwind.[8] The criteria include:
"The start and finish points of a course, measured along a theoretical straight line between them, shall not be further apart than 50% of the race distance."[6] "The decrease in elevation between the start and finish shall not exceed an average of one in a thousand, i.e. 1m per km."[6]

The article mentions “Not open conditions”. Other words, this course was chosen for the record.

I don't know for sure but I strongly suspect that Pratchett was heavily influenced by Operation Black Buck: https://en.wikipedia.org/wiki/Operation_Black_Buck In particular, this diagram from that page makes the process clear: https://en.wikipedia.org/wiki/Operation_Black_Buck#/media/Fi... Hopefully the name of the original mission is enough to help you find a link to some relevant mathematics :-)
That diagram is anything but “clear”.
Of all the aicraft that took off, only one actually flew over the target. It had to be refueled seven times on outbound journey, and the last tanker itself had to be refueled three times to fly that far.

I just formed my own officiating world record certification body called WASI; We All Saw It. WASI rejects who-evers claim to a monopoly on declaring who ran what, when, and where. WASI officially recognizes Elluid Kipchoge as the most badass marathon distance runner alive.
he's also the 'normal' marathon world champion. He just didn't exceed his own previous record with this because it didn't qualify in this category. You wouldn't allow a rocket propelled and self driving formel1 car into the same bracket as the normal league either.... Though the difference is significantly less here His achievements are listed on Wikipedia https://en.m.wikipedia.org/wiki/Eliud_Kipchoge
Anyone have estimated of how many calories he burned during this run? I wonder how much he ate before starting and when? Are they allowed calorie dense drinks during these runs? I do not do runs, walking sure, so I am just really curious how much it takes for the human body to do this type of run
They're worried about ingesting carbs to supplement what they have stored via carb-loading over the previous day(s) before the marathon.
Kipchoge has used Maurten supplements (see https://www.maurten.com/ ) for a previous race.
The commentators during the Ineos159 broadcast also referred to his use of Maurten supplements every 5km during the Ineos159 run.
Why Maurten? One of the supposed benefits of Maurten GEL is the use of two forms of carbs (maltodextrin and fructose).
Early carb supplements (Gatorade, etc) typically used one type of sugar to supply carbs to the body. The rate of carb absorption by the body was thought to be 1 gram per minute (60g/hr).
Researchers discovered that fructose was ingested via a different pathway than other sugars and when combined with another sugar could increase the absorption rate of carbs up to 90g carbs/hr. see https://www.torqfitness.co.uk/news/maltodextrinfructose for more info.
Kipchoge was taking drinks every 5km, at target pace of 21.1km/hr - 21.1/5 = ~4 times/hr
Each serving of Maurten GEL has 25g. So, assuming each drink is close to one serving of GEL, he'd get ~100g carbs/hr which his body would absorb close to 90%.
The support team also believed that the cause of Kipchoge's slowdown in the previous Breaking2 attempt was that Kipchoge wasn't supplementing enough and hit the wall near the end of the run. To reduce the chance of that happening, they gathered the used drink bottle after Kipchoge was finished and analyzed how much supplement was remaining. Not sure what they would do if they found he wasn't drinking enough other than verbal encouragement.

What was the "Class A time" for the Marines 20 years ago? No offense but if you broke 18 minutes (6:00 mile) for the 3 mile I'd be surprised. Kipchoge just ran a 4:30 mile for 26 miles. Hell, the best marathoner the US had in the 2000 Olympics ran a 2:30. Literally a half hour slower than Kipchoge.
> No offense but if you broke 18 minutes (6:00 mile) for the 3 mile I'd be surprised. Curious, but why? That's an extremely achievable time for anybody who is athletic and trains. (no disagreement that 4:30 pace is vastly more difficult than 6:00)
Not saying that someone couldn’t do that in a PT test but more often than not, people aren’t training to the level they’d achieve that. If they were running distance in high school, sure. It’s an ordinary time for a high school varsity cross country runner.
Given that "[i]t will not be recognised as the official marathon world record because it was not in open competition and he used a team of rotating pacemakers," Mr. Kipchoge's attitude represents the best of sport: "Now I've done it, I am expecting more people to do it after me... This shows the positivity of sport. I want to make it a clean and interesting sport. Together when we run, we can make it a beautiful worl…
