The chart is for the runner's pace over a marathon. If expect being fat to slow down your marathon pace way more than it slows down pace for a single mile.

Why would it be fake? He is simply encouraging people to run.
THANK YOU.
Funny how he is trying to get people active and involved with running and all anyone can focus on is how he is a heel striker and arguing how hard it would be for him to run a 10 minute mile. Keyboard warriors at their finest.
Sorry but you're data has some serious underlying factors. One is the height of the runners. It is much different if someone is 6 feet versus a 5.5 foot person who is 180lb. Also you are talking about 2 seconds per mile over 26.2 miles. Over this long period of time weight will certainly have a greater factor in the time.
Finally just having the weight does not consider the training of the runners. Some may have been trying to run a fast time, while others just wanted to finish, others could have just rand eith friends and family and ran slower, and others could have been coming from an injury, etc.
This all being said shows you how unreliable your data is and why it should not be trusted.
As a side note the 2 sec per mile for each pound sounds pretty ridiculous too many factors affecting performance that have a greater impact on times than weight.
I think once you get near your ideal racing weight it becomes more than 2 seconds per mile. You must keep in mind that you do not time travel straight to the race at a new weight, you train to the new weight. At the lighter weight training will become exponentially more productive. Keep in mind ideal race weight is different for everyone so you'd have to have an error period to find the bottom.

Okay, pace aside, is heel running THAT bad for you? I tried to switch to forefoot striking a few years ago and ended up injured in really odd places.
My only issue with Zuckerbergs form is that he's hyper extending his knee. It looks like he's not just going to touch down on his heel and roll off but really slam it into the track. With that said the surface is rubber, he's going slow, and individual form varies so who cares how he runs for one mile?

You are correct r^2 value is low. This means that not all 180# people run the same pace.
R^2 shows that only about 10% of the time can be explained by the weight. R^2 has almost nothing to do with statistical significance is almost irrelevant for many analyses. The p value shows high significance.
Wasn't trying to "prove" anything.
Don't know what you're looking at, but it shows the average 180# person (actual min is 185) ran 4:42 while the average 260# person ran 5:56, or 169 seconds per mile difference.
The biggest problem is that you have much fewer data points at the higher weights. I don't think this analysis can tell us much more than "heavier people run slower", which is obvious. But to put a number to it isn't worthwhile without digging into the stats more.
Sad how much this sounds like a thread TMZ would do. I don't know too much about TMZ other than the fact that they gossip. Obessessing over the wrong people and ideas. Who cares that Zuckerburg set a goal that some of you ELITES think is unattainable or will lead to injury...don't you do the same thing?!
He set a goal and has a cult following. Good for him. Also, people are ctiricizing the fact that he heel strikes.
Even if it is highly probably, the photo is not evidence enough. He hasn't hit the ground yet. Also, didn't all of you know-it-alls know that elite marathoners and barefoot tribes in Kenya heel strike???
*Note: this is not trolling, these are facts
Why don't we, instead of criticize people, educate them!! Scolding helps no one, it only deters them from learning and can turn them away from the subject.
So let's stop berating successful people and heel strikers, especially since the majority of the people who visit this site (yes, majority) heel strike.
Lastly, When did it go from LET'S RUN to ONLY WE ARE TRUE RUNNERS*
Hell, half of the threads waste text trying to define who is and who isn't a runner.
Rant is over. Needed to inject my furious opinion into this thread. Fight fire with fire.

I was trying to agree with you. 2 seconds per mile per pound (or more) is what I was trying to say.
No scholarship limits anymore! (NCAA Track and Field inequality is going to get way worse, right?)
