Here's a short story:

(CNN) -- When it comes to living on the edge, there are some women who have the tenacious spirit to conquer all. 

Whether it's scaling the world's highest peaks or becoming the first person to cross a dangerous ocean stretch, these extreme sportswomen have smashed records around the globe thanks to their fearless sense of determination. 

On the heels of Diana Nyad's record breaking swim, CNN takes a look at five sports stars who have reached the very top of their game. 

Diana Nyad 

After 35 years and five attempts at swimming from Cuba to Florida, 64-year-old Diana Nyad has finally made her name as the first person to cross the treacherous Straits. Wearing a mask to protect her from the trip halting jellyfish bites that plagued her last effort, the endurance swimmer is the only person to complete the 177 km (100 m) journey without either a wetsuit or a shark cage. Describing her achievement as 'a lifelong dream,' Nyad, who made her first attempt to cross the waters in 1978, was also congratulated by President Obama via Twitter.

Edurne Pasaban 

As a keen young mountaineer, Edurne Pasaban made her hobby into a record breaking profession by becoming the world's first woman to climb all 14 peaks over 8,000 meters. The 44-year-old Spaniard spent nine years working her way to the top of the world's biggest summits before completing her quest in 2010, and was named as National Geographic's Adventurer of the Year in 2011. With the likes of Everest, K2 and Kangchenjunga under her belt, Pasaban has seen some of the world's most beautiful landscapes from a viewpoint only reached by a select few.  (End of story)
