Business people, especially entrepreneurs, love a good motivational story. The details change from tale to tale, but the basic theme remains intact.

Man / woman has a dream. Man / woman encounters adversity. Man / woman doesn't give up. Man / woman keeps going. Man / woman wins.

There you go. There's your motivational quip for the day.

Some of these tales are real events. Some are probably embellished. Others are simply made up. Usually we don't really care too much. We just want to be inspired. We want to say to ourselves if this person can overcome that thing and accomplish all that, well then I should be able to tackle my challenges for today.

Some of the real stories are remarkable. These against-all-odds stories defy logic. Some are simply unbelievable.

And then there's Killian Jornet.

Killian Jornet is a sky runner. The Spaniard travels the world competing in the hardest ultra-marathons he can find. The typical race covers 100 miles through some of the most rugged mountain terrain imaginable.

He's the six time champion of something called the Skyrunner World Series. He's won multiple titles in the sport's biggest races including Ultra-Trail du Mont-Blanc, the Grand Raid, the Western States Endurance Run and the Hardrock 100 Mile Endurance Run.

He holds the ascent records for Mont Blanc, The Matterhorn, Denali and Mount Everest.

Killian Jornet is a legend.

Even so, what he did at this year's rendition of the Hardrock 100 can only be described as superhuman.

The Hardrock is a 100 mile jaunt through Colorado's San Juan mountain range. It boasts 33,000 feet of elevation gain (Everest is 29,029!) with multiple steep ascents of 13,000 feet peaks. Many professional runners do not finish after succumbing to changing weather, altitude sickness or edema. It's known as the hardest race on the circuit. It's brutal.

Like any race he enters, Killian Jornet was the favorite. But at mile 13, while running through a steep snow field he took a hard tumble. Dazed, he jumped to his feet 50 meters down the pitch only to realized he'd suffered a horrible shoulder injury. Using his other arm and the ground as leverage, he popped his badly dislocated shoulder back in place.

Medics begged him to drop out at mile 42, as the pain had advanced to the point of unbearable. Instead he fashioned a homemade sling and continued up the trail.

Between mile markers 55 and 65, he encountered a brutal wind and hail storm. Unbalanced due to the sling, he fell several more times, the shoulder barely hanging on. He was almost pulled from the course at mile 75, but managed to make it out of the aid station, undeterred.

All the while he battled American Mike Foote for the lead. In the final 11 miles, he surged forward outpacing Foote by 20 minutes.

His finishing time of 24 hours, 32 minutes, and 32 seconds was a slow one for Jornet. More than half the field dropped out.

"Yeah, I didn't think I could finish because at the beginning it was painful, then it was a bit better, but then the storm started and it was very painful," said Jornet in his post-race interview. "It wasn't easy. Yeah I wasn't sure I could win at all."

Wasn't easy? Wasn't sure I could win?

The winner of the women's race Caroline Chaverot of France also faced difficulty on her way to victory. Chaverot almost dropped out when she became lost two-thirds of the way through the race. She spent 90 minutes lost in the dark. Spotting another runner in the distance, she found her way back to the course, finishing in 28 hours, 31 minutes and 18 seconds.

"It's difficult to be motivated when you get lost," said Chaverot. "Then I said, Okay... my family is following and... I was lucky enough to get one ticket, so I have to finish. It was really difficult. I tried to motivate myself."

Difficult when you get lost in the dark in mountains? Really?

Just when you thought motivational stories had been tapped out, Caroline Chaverot gets lost for 90 minutes in the dark and wins. Killian Jornet separates his shoulder, pops it back in and wins.

Whatever you have going today, whatever you're facing, just keep running. You are capable of more than you think you are.
