Therefore there is nothing wrong with wearing inline skates to a running race as the same principle applies: "All the energy to do the work" of moving is still coming from the human. Can someone please get an inline skater to bandit this race and absolutely crush the 2hr barrier and we can let it go?
On it!
See you on the teevee!
Sitting beside the course as I type. Weather is looking good and they are doing final prep on the course at the moment.
Curiously, they have some LED scoreboards predicting a 2:02:40 finish.
As for the car/aero question, I can only speak from experience in car racing but there is certainly swirling and disturbed air very close to the back of a car - known as aero breakaway. That said, at the speeds we’re talking about, the aero benefit or otherwise has got to be negligible.
Cars are Audi SUVs this time, not a Tesla. I’ve seen three different Audis on the course this morning, two are camera cars and one is the pace car.
No need, the course record at Berlin Marathon is already under 57 minutes!

Is Bekele running this, that’s why they have a 2:02:40 predicted finish for him?

The same shoes but with different colours

"Basic Physics" post is absolutley correct. All the energy is coming 100% from the runner. There is not added energy from any mechanical device. Example a light bike is faster than a heavier bike. That not the same as adding a motor to the bike. This a very basic concept but essential to understanding shoe design and it's benefits. Why is this so hard for the average blogger on this page to understand?
Does anyone have an idea how much the pacemakers are being paid? 5, maybe 10 Gs?

As the event approaches, I had two thoughts.
1) Are they going to be letting him draft off a car with a huge scoreboard on top of it like last time as experts thought it made a big difference?
2) Are they going to be using an even newer and improved version of cheaterflies that will let him run26 seconds faster?
The answer appears to be yes and yes.
Here is a pic from the test event of the car.

Again, that is the same for using rollerblades or any other non-motorized device , but there is a reason we don’t crown the wheel chair racers the new marathon world record holders.

Lighten up. It's a joke term for the shoes on here. I'm sure Nike doesn't mind the free publicity.
Having said that, if Kipchoge were to use these shoes in Tokyo I would say he's a cheater. The rules are clear. "Any type of shoe used must be reasonably available to all in the spirit of the universality of athletics"
That rule change wasn't in place for Rio but is on the books now.
IAAF needs to enforce the rules. I think any shoe out there should have be commercially available for some time period before it's allowed in competition. Maybe 6 months. Then people from other shoe companies can decide if they want to use it.
I don't think there isn't much debate for the roads that the Vaporflys are slightly faster than old shoes. But 1% at the elite level is a lot. If you're an adidas, brooks, Hoka , guy for the Trials, do you wear the Nikes at the Trials? Will their company let them?

Anyone know if there will be a reply to watch if one is not up at whatever time in the middle of the night to watch it live on YouTube? Will the live stream just be able to be replayed when we go to it on YouTube?
All I know is that I would have loved to see him racing Bekele for the World Record at Berlin this year. Instead, we get this.

Thanks, Nike shill!
Now, go get a standard golf club, and drive the ball. Then, get a carbon fiber golf club, and drive the ball. See how the ball went further, with the same effort? Okay then.
Those shoes look like trampolines and make the sport look like a joke. All of a sudden, because it's Nike, it's okay to have the equivalent of the old Spira spring shoes that allowed a B-level Kenyan to run 26:01 for 10k on the roads on a downhill course one year.
All technological advancement in running shoes over the last 50 year has increased energy return from the shoe. No midsoles to midsoles. Cut EVA to compression molded EVA. Different types of of compounds within the EVA. Air bags. Track spikes have gone from plastic spike plates to p-back plates to carbon plates. All of these developments have increased energy return and made the shoe and those wearing them faster. Vapor fly 4% are just a extension of this evolution of shoe technology. But the shoe is still a "passive"- energy out does not equal energy in. At what point do you stop technology advancement? How far back do you go?
The people bashing the Nike shoes are the same people who are too broke to buy the shoes. If they actually had extra money in their bank account, they would immediately buy them.
So just for my own sanity, the race starts in less than 15 hours from now, correct?
