watching someone get glasses the first time. it's juster entiring. today we've collected and distributed over 425,000 pairs of glasses. i'm 17 years old. although many people believe kids can't make a difference, i have. anyone can do it. it's about being motivated and going out there and just doing it. a hundred miles of open ocean stretched between cuba and florida. >> keep it up, diana! >> water surging with currents, teeming with sharks and deadly jelly fish. a route so difficult, no swimmer has ever crossed without flippers or a shark cage. >> i'm barely alive right now, i'm just barely alive.

>> the swim starts here. she's going to jump in. now inside an extraordinary journey. >> seems almost like a treem dream to me, but now it's real. >> from the first strokes to the dramatic finish. five attempts, four failures, one xtreme dream. monday, september 2, 2013. diane nyad is swimming through her second full night. >> i'll admit to you my confidence is cracking because i don't know if i can do two more 13-hour stints. i couldn't find anything to eat, from chocolate to eggs to goo. i was violently vomiting.

>> her best friend, bonnie stoll, has news. >> she said, i never tell you things like this, but you're never going to have to put that mask on again after tonight. we're not going into a third night. >> not going into a third night, because bonnie hopes diana will have reached the shore before then. but the hardest miles are the last ones. >> the body and the mind go together. and as soon as the body starts to deteriorate, the mind goes with it. >> within hours, a fleet of boats approaches shore. as a crowd gathers. keep her energy up, keep obstacles at bay. diana knows that one bad moment at any time is enough to end the swim. a swim that's been her main focus for four years.

it all started in 2009. and diana was headed towards a birthday. a big birthday. >> i was driving in my car, telling myself, you better get with these life lessons. you can't go back, you better just seize the day. go forward and 60 isn't old. i was looking at the cars in the rear-view mirror and i caught a sight of my eyes for a second. and i thought, wait a second, maybe i could go back. maybe that would be the event that would make me feel strong and powerful again. would define me again. >> what once defined diana was marathon swimming. in the 1970s, she won races and set records worldwide. >> i'm interested in the most outrageously difficult goals that i can think of. i fail lots of times because it's so difficult, but i get wiser and wiser all the time. >> strong, brash, confident, a media darling. in august 1978 at age 28, diana

set out to do the most outrageously difficult swim she could imagine, cuba to florida, over a hundred miles in vicious currents, 200,000 strokes, 60 hours. she had a shark cage built, headed to cuba and launched from a beach surrounded by press, despite grave concerns. >> and i remember i got down to the shore with my six handlers and i have a picture of the six of us looking bewildered. we're looking out at a raging sea of whitecaps. >> her navigator promised calmer seas just offshore. but instead, diana battled waves for almost eight hours. hopefully off course and ravaged by bites, they pulled her from the water. >> it was very rough. you can ask anybody. >> diana's dream was dashed and her heart was broken.

>> i had never had summoned so much willpower. i've never wanted anything so badly. and i never tried so hard. >> the following year diana set the record for the longest unassisted ocean swim in history, going from the bahamas to florida. and then she quit swimming. >> the day i turned 30 was the day i swam up on the florida shore from the bahamas. and i thought to myself, i will never swim another stroke in my life. >> and for more than 30 years she didn't. summer 2009. as diana nears her 60th birthday, she realizes there's one dream that never left her. so she changes her mind and quietly returns to the pool. >> i just started going to a little country club pool swimming for 25, 30 minutes. and not fast.

kind of feeling if the stroke was there. seeing if the shoulders and the elbows and triceps would take the pressure. and i knew that the body was going to have to slowly come to it. so for those first couple of month, i just adding like ten minutes a day. >> then early in 2010, everything clicks into place. >> i did a 6 1/2 hour swim. cold. i don't like the cold. i came out shivering like this, that's the day i knew, i said to myself, i've got it. i got it in my spirit, in my body. this summer i'm swimming from cuba to florida. ♪ >> cuba, home of salsa and cigars, castro and communism. just 100 miles south of the florida keys. for diana, it's a place both complex and captivating.

>> this is a magical place. it's not just anywhere. it's cuba to florida. >> truth is others have attempted this swim before, even succeeded, but no one has done it the way diana now hopes to. just imagine this, 60 hours in that ocean with no rest, no shark cage, no flippers. diana wants to set the record for the longest unaided ocean swim in history. and she wants to set that record at age 60. the plan is audacious and maybe impossible. >> the swim itself that she's setting out to do is a super difficult swim. >> well, this is florida. >> david marchand makes his living navigating caribbean water. >> key west is right here. it's 103 miles and havana is right there. if it was in a swimming pool 103 miles it's a long way, but across the straits of florida, it's super difficult.

>> to make it, she'll have to build her body into a machine, so she's swimming every day for six, eight, ten hours at a time, hoping to conquer the one dream that has eluded her.

>> dr. ken camler is a surgeon that specializes in extreme medicine and knows exactly what diana's body will go through. >> she won't be able to keep up the energy and heat loss she'll be experiencing. >> impossible to do that? >> impossible to do that. the water is going to drain her, so she's going to be running at a deficit. as time goes on, the deficit will increase and she'll just be providing energy to those organs essential for survival. she's swimming alone, but she's in a race. she has to swim to florida before the point to where her body deteriorates to the point where she can no longer swim at all. >> to prepare, she pushes herself farther and longer. she's ready for her first test, a 24-hour training swim. her longest swim in 30 years. if she fails, it means the end of her extreme dream. >> let's call it 8:19.

>> the next morning, she plunges into the ocean. with diana in the water, bonnie stoll assumes command. >> don't worry about it at all. >> best friend. >> one hour. >> drill sergeant. >> on your first stroke, here we go. >> chief handler. >> bonnie is a rock. she's a take-charge, no-nonsense, say it in a few words. she knows me as an athlete. >> bonnie will lead an army of handlers that will follow diana's every stroke to nourish, encourage and protect her. one of their biggest concerns -- sharks. >> these are great waters for sharks. >> luke tipple is the team's shark diver. he knows how dangerous these waters can be. >> in this water we'd look for white tips, hammerheads,

caribbean reef sharks. this animal has evolved to dominate the ocean. they have a sixth sense. they can feel the electricity in the water. they know that we're there. >> that's why in 1978 diana swam in a shark cage. today she just uses this. >> sharks are tremendously sensitive to this. this is actually in the kayak. >> it's called a shark shield. and off the coast of the bahamas, tipple shows us how it works. it's a shark feeding frenzy at this block of chum, until tipple approaches and turns on the shark shield that hangs right above it. now the device emits a strong but harmless signal that overwhelms the sharks' senses and forces them to the ocean floor. >> green light means it's working. >> to keep diana safe, shark

shields are mounted below these kayaks. the electrical signals surround diana, keeping dangerous predators at bay. we're now thousands of strokes into her 24-hour swim. diana looks strong, but there's a problem. she's swimming in circles. >> you veer off a little and veer off a little more and you end up in jamaica. >> so after a while, i count every stroke look at that boat for hours and say stay closer. so i drift. every time i swim 30, 40 yards, we're adding on. we're going to add in the end miles. >> and that could be the difference between success and failure. fortunately today's swim was about time rather than distance. >> beautiful! >> hey, guys. we made it. >> and at 8:19 the next morning, she emerges from the water. exhausted.

>> i was racked. i mean, i was dehydrated and depleted much, much more than i knew i was when i was in there. >> watch her head, watch her head. >> and yet she feels confident. >> i really pushed. i was like cranking it. there was never a doubt, never a moment of doubt. i feel very strong i must say. >> strong, but it's only been 24 hours. does she have what it takes to survive a swim more than twice as long? vo: two years of grad school. 20 years with the company. thousands of presentations. and one hard earned partnership. it took a lot of work to get this far. so now i'm supposed to take a back seat when it comes to my investments? there's zero chance of that happening. avo: when you work with a schwab financial consultant,

>> turns out even elite athletes sometimes lose their luggage. >> thank you, thank you. >> good luck to you in finding your bag. that will probably be harder than swimming from cuba to florida. >> now everything in key west kicks into high gear. the team flies in. the boats are prepped. and then just hours later, the forecast turns. and the weather window vanishes. >> that put everything to a halt. it was a setback for many, a chance to improve things for others on the crew but diana got to have her very first meltdown, which she needed to have. >> i just bawled like a baby. for me it's like will this ever happen? >> diana decided to turn it to her advantage. she takes the team out for a training swim. her goal, to work out a few kinks. >> we're ready. 7:40 in the water, okay? >> like her difficulty swimming

"the day has come. the seas here today have dropped to 77 degrees, far below my threshold for such a long time in the water. this was my year.

i believe i got in better shape both body and mind than even in my 20s. it has been draining, whipping of a spirit to feel it all slipping away from me." >> it's over for this year and that's okay. the swim will get done. >> i don't think i could do it without you. >> you're our inspiration. >> she's allowed to be disheartened. oh, my god, i have to do it again. and that will come, too. i can't wait to do it again. >> los angeles, six months later. >> i'm now full tilt, you know, in it again. >> you see, for diana quitting wasn't an option, and yet these long months of training have taken a toll on her 61-year-old body. >> this shoulder has a tear on the biceps tendon, which is right in the front here. i went to an orthopedist. he said it's a considerable tear, you'll never do it.

>> so diana found another doctor with a better outlook. >> icing around the clock. >> and at another swimmer's suggestion, she even changes the stroke she's had for over 30 years. >> you're going to start swimming with your shoulder down. so i changed my stroke. i'm in way better shape even than last year. just strong, strong, strong. strong as a bull. >> strong and ready. but can the new stroke work? will the torn shoulder hold? and will that weather ever come?

[ cheers and applause ] >> just hours later, she spoke to me for her first full interview sense reaching shore. how are you? >> you know, you know what's so great about it, sanjay? it's all authentic. it's a great story. you have a dream 35 years ago, doesn't come to fruition but you move on with life. it's somewhere back there. and then you turn 60 and your mom just dies and you don't know, you're looking for something and the dream comes waking out of your imagination. no one's ever done it. i'm not sure when the next person will do it is.

that's how hard it is to get everything right. when i say everything right, with all the experience i have, especially in this ocean, i never knew i would suffer the way i did. start with like glass. 90 minutes later, for 49 hours, the wind just blew like heck, and it was rough. >> are you hurting right now? >> i was hurting then. >> i mean, i know your face is swollen. >> that's okay. that's temporary. but 13 hours, partly because of the daylight being less these days, to avoid the fatal attacks of the box jellyfish. they're close to 80% fatal, no matter what the sting is, how small, what part of the body. and its sting is immediate. it takes your heart, your lungs and spinal cord of any animal it

stings. so i had a prosthetic mask made. it's brilliant for jellyfish. box jellyfish wouldn't penetrate it. i wasn't stung and they were there. but i could open my mouth and you have silicone on your face and you can't feel the waives. so you're inhaling gulps and sips of saltwater. so i was whipped. when i got that mask off in the morning, i told myself, two more nights with that thing. i don't know. where will i find a way for that? what lifted my spirits was, bonnie told me that we were not going into a third night. we're finishing in the day, if i can just make it through sunday night. >> there is nothing that will stop you. you will go, go, go! >> the wind is bad, but the gulf

stream is going due north. it's a ride. you never get that kind of ride. >> what about sharks? >> we had a great shark team, great guys. brave, experienced. they're just going to, in the black of night, they're just in there, looking for eyes. and if the eyes are very far apart, it's a large animal. i thank them. they patrol, i see them all night in with me. >> at those times when it was really tough, when the wind was blowing hard, the squalls, what do you think about? you're such an inspiring person. what or whom inspires you? >> you know, sanjay, i'm just like every other human being. even the bravest soldier has souths, has fears. and i'm no different. but i decided before i went into this, no matter what happened, i

don't want that experience again. i didn't want to be here packing up again, and deciding if it's worth trying again, do i have anything to bring to the party. my whole mantra this year was, find a way. you don't like it, you're not doing well, find a way. >> find a way, i like that. >> find a way. so it was really rough that first day, saturday. after the start. and i just said, forget about the surface up. get your hands in somehow, and with your left hand, say push cuba back and push florida toward you. >> you got this! you got this. crawl if you have to. you got this.

>> you've just gone through something nobody has ever done before. has that set in? >> yeah, because i've been trying for so long, and because today i had 15 hours. you can see last night the lights of key west, and our navigator said, it's probably going to be about 15 hours of swimming. but i just believed in it. i believed i could make it. >> i've got three messages. one is, we should never, ever give up. >> yeah! [ cheers and applause ] >> two is, you're never too old to chase your dreams.

>> that's right! >> three is, it looks like a solitary sport, but it's a team. good evening. we begin with breaking news that iran may be plotting a retaliatory strike against the u.s. embassy in baghdad if there is u.s. military action against syria. that's coming from a senior u.s. official that sopoke with cnn's barbara starr. the united states is looking at all intelligence from the region as september 11 approaches, which is not only the one-year anniversary of the attacks in bep benghazi. and a major correction by "the new york times" over a video purportedly showing syrian
