Swimmer Diana Nyad was forced to abandon her attempted swim from Havana, Cuba to Key West, Florida, according to an AP report. Nyad had made a point to address that no sharks would be harmed by her team during her swim. Nyad had hired a team of professional divers with many years of experience diving with sharks in order to protect both her and any sharks encountered during the long-distance swim.

CNN reports that Nyad was having trouble with shoulder pain, asthma, and nausea. Nyad faced strong winds and currents in addition to her problematic physical symptoms. Nyad was forced to abandon the swim 29 hours into the journey.
