My experience is that GPS measures short. Its refresh rate is slow enough that corners and curves are cut off.

The time and the course make the "World Record" meaningless. The sustained effort over that distance however, is mind-boggling! Metronomic splits run in tandem will always yield maximum efficiency. The gene pool of Kenyan talent has barely been tapped and will only continue to grow with victories such as this.
Stunning!@!!¡€_+

In 2 minutes, 58 seconds! Duuuuh! ;-)

No! The problem is guys like you become race directors and start using GPS to measure the course instead of the more accurate wheel.
I ran one 10km course through thick trees with no possibility of a GPS signal that probably measured 6.7 miles. But it was exactly 6.2 on the Garmin! Experienced runners had raced in previous years were much slower and they knew it was long. The hobby joggers were like "finally a course that isn't short".
GPS might be more accurate if you race across a farmer's field.
So throw away that GPS and measure with a flipping wheel.
I can't imagine anyone any time soon going through the first or second HM in less than an hour, let alone back-to-back. But, damn, a 1:01:12 second half is impressive.

breaking 2:04 now becomes similar to breaking 1:42 in the 800 in terms of the magnitude of the accomplishment: rarely happens, and is awesome, but the next threshold has already been busted through.
You are all idiots. There is a very long and complicated process to get a course certified and ratified for a record. A race director wheeling a course doesn't cut it, and certainly not GPS. Even a USATF certified course goes through a high detailed process that must be certified every few years due to course degration.
If you think any Joe Schmoe can go out, wheel or gps a course and have it count as a record you are mistaken. Not saying it doesn't happen, I. E. Alberto in New York but the course had to be measured for the record. So will this.
You a damn fool. 1:42 for 800m has been broken 5 times in the last 40 years. It's only a slight exaggeration to say that every 2 weeks a kid in east Africa decides on a whim to see what a marathon is like and runs 2:03:xx.

You're wrong to overgeneralize but- the best way to measure is with the Jones Counter.
GPS usually measures long but I suppose it could have lost the signal since it's in a city.
How many men have broken an hour for the half? Do you really think anyone will EVER run back to back sub one hour half marathons?

A quick look at all time athletics
http://www.alltime-athletics.com/men.htmshows that in fact 1:42 has been broken 14 times in the last 33 years. Sub 2:04 on the other hand has only been run 8 times, in 6 races, by 5 different men; on record eligible courses.
The comparison was very reasonable. When Rudisha ran 1:40.91, 1:41 remained a hugely respectable time but it showed us the possibility of something greater. After today's race nobody is going to be looking down at 2:03, but the impossible just got a little bit closer.
It took 6 years to go from 2:03:59 to 2:02:57. The lower the time gets, the harder it will be to continue advancing the record. This would suggest that it will take more than 6 years for another minute to come off and produce a sub 2:02.
A counterargument to this is that the marathon is red hot right now with the money and a multitude of East Africans going hard for it. No one knew who Kimetto was until a few years ago, so nothing is stopping someone else like him from showing up and smashing the record some more.
Can we stop saying that Mutai's 2:03:02 from Boston was aided?? That fool crushed E. Mutai and E. Mutai ran 2:03:13 today.
Boston that year was as legit as they come.
LEGIT TOP 5 ALL-TIME
2:02:57, Dennis Kimetto (KEN)
2:03:02, Geoffrey Mutai (KEN)
2:03:05, Moses Mosop (KEN)
2:03:13, Emmanuel Mutai (KEN)
2:03:32, Wilson Kipsan (KEN)

No, no we can't.
Did you run Boston that year? The wind was a huge help, esp for faster runners as wind resistance is a quadratic function, your speed doubles, resistance goes up approx 4x. That was also over 3 years ago, E. Mutai is much faster since then. G Mutai is also probably faster.
If Kimetto ran Boston that year with his Berlin fitness, he would have easily run sub 2, even if he had to stop and take a dump on your brainless head.

Wheels are not accurate because they wobble side to side, and there is no steady pressure on the top.

Where was he today?
Mutai's fastest legitimate time was 2:05.
Heck I ran a WR mile in 3 minutes around the block this morning, nevermind that it was only 880 yards.
not if you use a pressurizer on the top. Very useful tool to stabilize the wheel.

Cars and gps are useful too, which doesn't make them accurate.
A wheel is not accurate.
The only thing it's useful for are cross country courses where it's not feasible to use a bicycle with Jones Counter.
