Survivor takes on mountains and marathon

What would you do if you had climbed Mt. Everest and reached the summit of six other peaks in Africa, Europe, Australia, Antarctica, North and South America? Well, if you're Sean Swarner, you'd run in the Boston marathon today. Sean, who is the first survivor to summit Everest, was twice diagnosed with cancer at ages 13 and 16 and given only 14 days to live after his second diagnosis. Instead, Sean went on to complete many athletic challenges, including the Iron Man challenge in Hawaii, and he cofounded a nonprofit organization called the Cancer Climber Association. And now he's added marathon runner to the list--despite the heat advisory this morning. Having finished the race, Sean tweeted, "2 weeks training, 8 weeks post-knee surgery, Boston marathon in 90 degree temps. Not too shabby. Lol Thanks CT Challenge for the opportunity."To hear more about Sean in his own words, check out the video below:
