Nyad in good spirits in 18th hour

Now 18 hours into a 103-mile swim from Cuba to Key West, Diana Nyad continues to swim with a vengeance.

Some 76 miles away from American shores, the only issues plaguing Nyad are a nagging pain in her right shoulder – the opposite shoulder than the one that had bothered her leading into the swim – and some shortness of breath.

Dr. Michael Broder, the team’s physician, jumped into the water with a stethoscope to assess her lungs, but suspected that her breathing issues may be a result of an allergic reaction to some of the anti-inflammatories she took for the shoulder pain.

He was able to give the swimmer a few puffs off of an inhaler to open her up her airway.

Overall, Diana’s handlers report that she is well hydrated, swimming strong despite the shoulder pain and is in good spirits. The shark safety experts on-board Diana’s chase boat have had to launch into the water only twice, after seeing some large tuna swim by.

The divers were concerned that larger predators, like sharks, could be lurking nearby but found no evidence of sharks in the surrounding waters.

    She is now at the point where mental toughness is the key to her progress. Everything has been done to get ready and the support crew is earning its keep. Now it's up to her. This is her time to be all alone in her world and move from one small success to the next in her push toward the finish line. I've run ultra's and this middle ground in an event is where you find you are really all alone no matter what's around you and it's a great place to be.

    Unfortunately, Diana wall pulled from the water at 29 hours into her swim when she started vomiting, I'm sure more will be known soon.
