Yes, but it will improve your presentations in much the same way that screeching car tire and ricocheting bullet sounds improve PowerPoint presentations.

So everyone should use it is what you're saying? I'm a star fade man myself: use it every couple of slides to keep things interesting.

They've improved star fade, if that's possible... You keep scrolling down until you are certain that there is nothing left to see and then, suddenly... star fade!

Here's the hypothetical scenario that the report describes in the end. I've found reading the analysis after this story makes it an even better read: The road is so flat and straight, you can see them coming from a mile away. Six runners flow in arrowhead formation around the Canadian city of Saskatoon. The early November air is still and dry, the sky overcast, and the temperature hovers a bit above freezing, just as…

Why is it that drafting is allowed in world records? Why not just break the record by having a big draft train like in cycling? Cycling records don't count if drafting is involved, in fact.

Because the benefit is pretty small compared to what you can save in cycling. Now it's certainly there, which is why you want to save the extra 5% for the 2h mark, but it's not the 40% you get in cycling on the flat (drag grows faster than linear).

Basically what drugs allow you to do is recover faster and better - which allows you to train far harder than your clean competition and build all of these superhuman stats you enumerated. A famous cycling reporter took drugs for a month to see just want the effect was and apparently it was like being superman. He would go out and ride 100 miles (something that normally leaves you in couch mode the next day) and be r…

Hmm, I wonder what the long term effects of these drugs are. Medicinal and therapeutic use may be very promising for average people just trying to stay in shape. If the long term effects aren't too terrible, say like that of coffee, then greater acceptance may be possible. Also, as toward the 2 hour marathon, drugs that are psychoactive may be of as great a benefit as the physical ones. Not just caffeine and other pl…

Is there software that makes it easy to put together a presentation / design like this? (e.g. wysiwyg / point-and-click)

This presentation made me leave the page before the first graph, because bits would only start to appear half cut-off at the top of my window as I scrolled down. I'm using the latest version of out-of-the-box Firefox on a desktop, not some gimpy "browser" on a tiny phone or IE6 or heaps of functionality-destroying add-ons.

Looking at a different pivot to the question, Allen Downey gives a good theoretical reason for the decline in times and projects 2041 as the year for the 2-hr marathon. Also, his original projection was made in 2011, so there are three years of data to compare against, which is interesting. http://allendowney.blogspot.com/2014/09/two-hour-marathon-in...

The whole article is beyond stupid. It's impossible to seriously discuss athletic records in 2014 and not mention drugs. No discussion of steroids, blood doping, hgh, nothing. For context, the major marathons just increased their drug penalties [1]. The second they get serious about testing they'll discover they have the exact same problem as bicycle racing. [1] http://www.bmw-berlin-marathon.com/en/news-and-media/ne…

The article did mention drugs, specifically EPO which is used to increase VO2 Max. Steroids would be less useful in a runner since they add muscle mass and dragging any excess weight around a 26.2 mile course is counterproductive. The article mentioned that EPO could be behind either the recent world record times or the eventual sub 2-minute time.

Corticosteroids are used to improve recovery time and to help reduce pain and inflammation. They are routinely abused by cyclists, who are also endurance athletes who seek to minimize body mass.

I especially like this paragraph from the story: "Kenyans and Ethiopians have dominated the marathon since 1999; in fact, of the 100 fastest marathoners in history, 59 are from Kenya and 31 are from neighboring Ethiopia. Is it genes or environment—nature or nurture—that is responsible for this overwhelming domination? The answer doesn’t actually matter when it comes to who will run the first sub-two marathon. The suc…

A lot of the success of Kenyans and Ethiopians is probably down to the economics of running (which is to say, it is an easily accessible sport to even the poor) and the feedback loop of other successful Kenyans. Kimetto, the recently crowned world marathon record holder, was a subsistence farmer just years ago ( http://www.runnersworld.com/elite-runners/from-poverty-to-po... ). There are simply no western school kids…

You make it sound like the Africans are the only ones racing. There are plenty of Euro/Asian/American runners competing for it and probably had much better infrastructure and training counsel than their African counterparts. Yet still, the Africans dominate. By definition then, its definitely more than just 'economics' and certainly more to do genes/physique/etc.

Speaking to your question about "what the long term effects of these drugs are":

My wife put together a together a pretty interesting video about the "faustian bargain" which is IGF-1 (used as a proxy measure for growth hormone)... video is replete with examples of the effects of low IGF-1/GH or high IGF-1/GH both in animal models and humans.

One of the more interesting points in the video is the fact that people with polymorphisms that make their IGF-1 receptor experience some slight loss of function actually live longer (in general).

The video also links to an article which has a bibliography if you're interested.

Great article; it got me wondering how much the oxygen weighs that an elite runner would use in the course of a marathon...

For the Berlin track (Because it's level and close to sea level), and the average elite:

1.00 atm * 8.1L = n * 0.0821 * 331.8K

n = 0.30 mol, @ 32.00 g/mol = 9.5 grams 02
