    How fast do you think Diana would've travelled if she'd simply flipped over on her back and floated once she hit the Gulf Stream?

    BTW, this is the best moderated, most entertaining, educational internet forum string I've ever followed.

    Some of you might appreciate my tongue-in-cheek blog post - http://tricoachmartin.blogspot.com/2013/09/diana-nyad-gulf-stream-and-olympic.html

    Olympic 10km swims are in current neutral water so not really an apple to apples comparison.

    If you want an even more extreme example, the record for MIMS (a 28.5 mile swim) is ~5h:45m or nearly 5mph (8km/h) sustained. Current assistance can indeed be awesome (heck see my previous post)

    ADMIN NOTE: I deleted several posts that were not germane to the current topic, the last of which was a re-posting of a within-Forum private message, which is not allowed.

    No more follow-up posts on the points made by @Lisa. Thank you.

    If a person continues a discussion started in a thread by improperly sending an unwanted and unsolicited private message, either the private message should be allowed to be republished, or the person sending offensive personal attacks under the guise of a "private message" ON THIS FORUM then the person doing such should be banned from the site.

    The preferred course of action in the instance of a private message that the recipient finds to be offensive is to contact the Admins, rather than posting it publicly. Thank you.
  • Hey all, I'm not an open water swimmer, just a ~1 mile pool swimmer who happened to develop Diana's website. I hope what I've provided here helps a bit with fact-checking, and I've passed more data on privately to @evmo, @malinak and a couple others so they can fact-check that. I think I've contributed about as much as I can here besides "You guys are so impressive!" so I'm gonna bow out unless needed further.

    Before I go I want to make just one quick appeal. When the Boston bombers hit my hometown's marathon earlier this year, I wanted answers - a good and reasonable feeling. But when members of an internet forum (Reddit in this case) wanted answers, they took it a step further and jumped to conclusions. They posted their evidence, their analyses, and over about a week built it up to identify what they believed to be the 2 bombers. Even though the experts (the FBI in this case) were doing their own parallel investigation, they concluded they had the right answer, and announced their conclusions with certainty. They posted their faces, their names, their addresses. Since then, one of the 2 has turned up dead, a presumed suicide, and the other's family left the country to get away from the in-person harassment. Days later, the real Boston bombers were identified by the FBI - neither of the 2 identified on Reddit were actually guilty of this crime. I doubt there's anyone here who hasn't heard the rest of that story.

    I love data, and I love science - skepticism is good. But asserting a conclusion comes with risk - often asymmetric risk in that the person making the assertion risks little, while the target risks a great deal. What's at stake here is much less - no one's life hangs in the balance. But someone's legacy does, and I hope all those who feel themselves starting to jump to conclusions stop and think of what's at stake. What if you were the one who had tried so many times most of who you knew had given up on you. What if even you had given up several times, promising begging friends not to try again. And then, one day, you pulled it off - probably even surprising yourself? What if it was you.

    Be reasonable everybody, and be good to each other. And once again - you all impress me.

    For me, whether or not Diana accomplished this feat currently pales in comparison to the un-sportsman like comments regarding other attempts at this crossing:

    "At her post-swim news conference on Tuesday, Nyad admitted that she had not been rooting for McCardel and that she was miffed some members of her team would jump ship to work for a competitor"

    Apparently Diana Nyad lives on Planet Nyad, where special-needs physics and justifications abound. She does not take our sport seriously and appears to be merely interested in being the entertaining "motivational speaker" and selling her story.

    Regrettably, I bought one of her "extreme dream" teeshirts during the original attempt a few years ago with the belief that this was a real attempt by a kindred spirit. This piece of fabric has been relegated to wiping the toilet bowl...

    @b9chris - I want to join @malinaka's public Thank you. I respect and appreciate you coming on here and contributing as you have - openly and thoughtfully. Frankly it's a great credit to Diana's team.

    All the best with your web dev business - and your swimming too!

    I have to make another Admin announcement following @evmo's, and I'd like everyone to take note.

    We have a PRIVATE Message system. The vast majority of members respect this. It's one of the benefits of actually joining the forum, rather than lurking. With the private message system you can have direct contact with some of the world's best marathon swimmers, make new friends, have sidebar discussions, ask advice or offer help.

    We have had two violations related to this thread. Forum rules are now explicit. Violating the privacy of the message system will lead to a no-appeal immediate ban and the violator will not be allowed to re-join the forum.

    I'd like to join @evmo & everyone else in thanks to @b9chris for his public and private engagement and openness, and hopefully he'll stay active as a member, maybe we can get him to sign up for his first 10k!

    From the start I was skeptical, if only because of her previous attempts. I found her blog and saw pictures of her being helped with putting on her suit. But even that didn't bother me, because I swear I remember her or her team stating that she'd be wearing the suit for this swim. I could even take the streamer, again, because I'm pretty sure she mentioned she'd be using it.

    But when I read that she went without food or drink for more than 7.5 hours on the second night, well, then I no longer believed anything coming out of her camp. I cannot imagine someone in that state of exhaustion could go that long without at least water, and I don't believe the medical professionals in her flotilla would allow that. Her supporters or crew, the few that have come on here, haven't helped her case any either, with the sole exception of @b9chris, whom I would like to thank also.

    I don't know if we'll ever know for sure. But I learned that should I ever attempt a swim that's not been done before, I'm certainly going to have independent observers' reports and lots of evidence available for all of you to review!

    Kudos to Evan for starting this thread. It has drawn no less than worldwide attention. Hopefully, this discussion and debate will move our sport in the positive direction it deserves. Marathon swimmers are a special breed. The breadth and depth of this discussion reflects that. From my perspective, it is among the best substantive discussions I've witnessed regarding a sporting event in a long time.

    Keep moving forward.

    One COULD interpret that as social engineering or perhaps a confidence trick. Legitimize yourself by comparing yourself to other professionals.

    @evmo, this is great. Please let her know that we are not "haters", that we are not being petty and that the questions are not due to "sour grapes". I am sure she understands that such an incredibly unprecedented swim needs to be vetted and verified for posterity and to aid anyone who may wish to follow in her footsteps in the future.

    "...the tactics she employs — like letting her crew remove her shark suit and apply lotions. Many swimmers say those violate the most common rules of the sport."

    Yes, that's called an 'assisted' swim and should be recorded as such and for the other deviations away from Channel Rules (yes, I know she didn't say she was following Channel Rules) - they all need to be recorded.

    Just as she wants to be known to be the first to swim without a shark cage, the next person should be able to say they are the first to swim it unassisted or with less assistance than DN used (directional streamer or without people helping in/out of a suite, etc.) or use the same assistance and swam it faster/slower, whatever.

    It was an assisted swim. State the assistance so that the next person can swim it and say they were first to do it without a shark cage and streamer and blah, blah, blah until you get to EC clean if possible.

    I'm not so sure why that is so hard for DN and her camp to understand this. They were very clear to finally change their positioning on this swim "first without a shark cage" instead of "first [ever]".

    Btw sincere thanks to Evan and Donal for animating this debate so well - and for going into the lion's den... - to @malinaka and others for some essential number crunching, and to @b9chris for having been such a great levelheaded contributor from DN's team.

    Who said that open water swimming is not a spectator sport?!
  • IronMikeIronMike Northern VirginiaCharter Member
    Got another great comment on my blog from an Xtreme Dreamer:

    You sir, are a sexist pig you claim to respect Nyad swim but you infact belittle her with comments like this and I quote;

    Yes, "Pro" swimmer, but add in her feed stops of 12 min long, and those stops where her crew would clothe her and put her make-up on...but I guess you're right since she made up all that time on night two what with not needing water or feed for 7+ hours.


    Put her make up on??? It's called sun block. You said make up because you were being sexist - She's a woman so she wears make up! Pathetic!

    I would love to see you do that swim all the way - without sunblock.
    You are just a bitter little no-body who has to rain on someone's parade because you have no parade of your own.
    Do one - Ironpatheticmike!


    Uh-oh! My sense of humor was a bit much for Realswimmerfan (who also has an interesting email, which I'll not put on here for his/her protection).

    For the record, I was jokingly calling DN's jellyfish preventative gel "make-up" because in one of the videos (http://www.youtube.com/watch?feature=player_embedded&v=noUwjRZH-FI), it looks like a make-up artist putting make-up on her. It was not sunblock that I was making fun of.

    Ironpatheticmike, I like that!

    There will also be segments airing tomorrow on the NBC Today Show, and on CNN's New Day.
  • IronMikeIronMike Northern VirginiaCharter Member
    @Jimeboy, the quoted comment was seriously left on my latest blog post. Other than that, nothing I said about parades was serious. ;)

    BL: if DN were a man who had helpers in the water applying jellyfish gel, I still would have called it make up. (Also much easier than typing "jellyfish preventative gel" every damn time!)

    The analogy I have been using with non-marathon swimmers is: This is like me claiming that I broke the world record for running a mile, and… you are only allowed the watch the beginning and end of the run and in the middle I take credit for running faster than Usain Bolt can run 100m… yet my pace for the parts you were able to see were about a third of that speed. My story would deserve skepticism, wouldn't it? The analogy seems to work (at least with people that know me).

  • mrfinbarrmrfinbarr Charter Member
    In my opinion the team at this stage has confirmed this is most certaintly an assisted swim, she was helped by an ocean current which moved a 1.5mph swimmer at 7+mph. This places it firmly in the category of Martin Strel's epics rather than Penny Palfrey's

    Does anyone know if the google earth download of the track on DN's site- a manually produced document (working off manually produced cordinates ) or a copy of a spot track ???
  • I am disappointed. I really thought that we would be the first web forum to bring the entire internet crashing down and dying a horrible death by overloading it, but it looks like it will survive.

    Next time I suggest that we get Kim Kardashian to claim that she swam from Cuba to Florida in a skimpy bikini. That should do it.

  • Zero current, Diana Nyad no way could have done the swim. Look at the video of her swimming. Slow. Penny Palfrey, zero current, easily could have done the swim. Penny is strong and fast. I have escorted many swimmers across various channels, including Penny in Hawaii, Caymans and her Cuba attempt. Question to the Open Water Swimming Community. How can you ever get a level playing field? Diana could have perhaps got the once in a lifetine perfect current where she could have floated on her back the whole way and made it while Penny got serious cross currents pulling her out into the Atlantic and didn't, even though she was a much stronger and faster swimmer. All this is very confusing. Open water swimming is still evolving and I'm stoked we're having this discussion.

    IronsexistMike, I just looked it on my laptop and it's only a couple of sentences. Enjoyed it and want to see the whole interview/discussion. Hopefully I can find the full thing on tv tomorrow before I go to work.
  • I must say that I am pleasantly surprised by the quality of the media coverage on this issue. The interviews with Evan and Grace were really nice and interesting to listen to. I also think it has been really nice the way Diana's team has been willing to share their GPS data, and I hope the discussion tomorrow goes well.

    I may be a little late to the game on this issue, but just wanted to quantify some of issues with Diana's speed and the assertion by her team that she got a rare Northward current assist. I will preface this saying that I am a physicist by training, so I'm to handling data and vectors and all that, but I am not an oceanographer so I'm slightly outside my area of expertise.

    I've been looking around for current data for the dates of her swim, and so far the best I could find was the NCSU model available on the SECOORA website (a few people have posted images from this site earlier in this thread). This Regional Ocean Model uses a combination of satellite and buouy data with a detailed numerical model to get the current, temperature, salinity etc in the region with very good spatial and temporal resolution. These models aren't perfect, but they are used in things like hurricane forecasting, tracking pollution (eg the BP oil spill) and things like that so a lot of work goes into them.

    I overlaid Diana's GPS positions on the surface current flow fields for the days and times corresponding to her swim. A few are shown below, the rest are available as a movie shared on google drive. The purple arrow shows the magnitude and direction of the current at Diana's position at each given time. As you can see in the examples below, the current is mostly perpendicular to her and I do not see the rare south-north current they claim to have ridden.

    https://docs.google.com/file/d/0B-PBnlGWL25caW5wX1ozcFNoMm8/edit?usp=sharing

    (let me know if you have trouble with the movie)

    Plotting her speed, bearing, as well as the current's speed and bearing, you see that this is generally the case for whole swim. (I used the same gps data set as in my last post, just took only the data at 3 hour intervals after applying a 3-point average to the raw data). If you add up vector for the current and her absolute velocity to get the speed she must have been swimming to maintain her course, you see that if anything the current makes things worse, since she has to account for the very strong cross current.

    image

    This isn't completely definitive, the true currents could differ from the NCSU model. However, they would have to differ by a whole lot. Like, pointing almost a full 90degs in a different direction. A 'rare current' like this should show up in other oceanographic data, and not just be localized to her boat crew. If there is some other data somewhere showing a 2mph current from Cuba to Key West during her swim, that would make the speed issue disappear. But absent that, both general picture for how the gulf stream works and specific modeling info for the days of her swim paint a very different picture.
