I wonder how long it takes for someone to complain that this is a "spoiler"...

Awesome.

Why can these races use a pacer but not in other events like triathlon?

just because

The question now comes up: is this a 'real' time, or is it a pharma-enhanced time?

If you have pacers is it still an individual event? Isn't like having a team? When was the last Marathon WR set without pacers? A true individual effort.

I agree...but those same folks would have have said that knocking 26 seconds off the current WR wasn't in the cards either...

Concludes Tucker, "Bottom line is that talking about a sub-2 hour performance after seeing a 2:03:38 improve to a 2:03:23 is just not feasible. The next barrier is 2:03, and I'm sure will go within five years. Then we can begin to work towards 2:02, which will take another ten years, perhaps."


by this line of reasoning the records should be getting broken by less not more...and, it also supposes that the half record is not at all soft (obviously, a very relative term to mortals like us)...


His piece was written a year ago...so, we are 4 years ahead of schedule to a sub 2:02 on his calendar...(I know he said "within"...but you know he didn't mean next year)

His average marathon time is 2:04:27, meaning that not only does he hold the fastest ever, but the fastest mean time ever as well:
2:04:16
2:06:50
2:03:45
2:02:57

Awesome. Thought the Berlin marathon was today.

2:02:xx I guess that's a new milestone. Congratulations to Kimetto but I will admit I've never heard of him.

Marathon has never been an individual effort.

No they would not have. Within 5 years. Not, at least 5 years =)

Definitely didn't mean for it to be a spoiler - actually thought about that on my long run this morning, though.

I disagree with the premise that pacers somehow propel an individual to a faster time, like drafting vs time trialing in cycling. The pacers are there as a benefit to the promoters, to ensure a fast race for time rather than a tactical race for place. When a racer agrees to race in a race with pacers, that racer is effectively agreeing to a non-tactical race against the clock. A cycling TT rather than a cycling road race. There will be no ditzing around tactically. Any benefit provided by the pacer is negligible; drafting effect at 13mph non-existent, the only benefit would be mental in that you know you can check out and just follow the pacer and know a proper pace is being set.

Would a solo marathon effort on the track be considered an individual effort? I presume so, although that individual could pace precisely with splits every 400m or more regularly, eliminating the role of the pacer.

I think we need to do some math on the drafting, I am curious.

But yes the main benefit is setting a steady fast pace. It should be noted that pacers can, and sometimes do, win the race. They are fully legit competitors in the race.

Well they have been using pacers for about 15+ years now in triathlon, only they are called domestics. And since time means nothing in triathlon because no two courses are the same distance, the pacing is used to win the race, not always to get the fastest time. Of course in triathlon the pacers are only used in the swim and bike, runners are left to their own by that time in the race..

power to overcome drag @ 12.7,mph is 53 watts assuming a runner has a cda of .5

32 watts if cda is .3


I don't know at how to guess how much a person running in front of you reduces the drag, but certainly significant power is on the table.

not much help for drafting on a course like berlin marathon. It is more a psychological effect, the need for humans to compete , the visual chase...

You really can't avoid that question given what we have seen with doping in Kenya.

There's certainly some variability, and the 15-second drop was a rather small one. This one is more normal-ish, but it's rare that anybody breaks it back to back years...but it's not reasonable to assume we're going to continue to see the record drop by 20-30 seconds year after year. Even if we did, you would still be looking at 7+ years.

it is. shocking how little decency and consideration there is in this place.

For the entire run.

Thank you! Going to watch but starting at the halfway point.

This paper might interest you: http://www.ncbi.nlm.nih.gov/...org/content/48/4/702

They say that wind resistance accounts for 2% of energy cost in marathon running, but for 5 m/s speeds, so it'll be somewhere between 2% and 4% - not very much. This RW article paraphrases the paper.
