71-Year-Old Woman Finishes Incredible 100-Mile Run

71-year-old Gunhild Swanson tackled the 2015 Western States 100 mile ultramarathon recently, and with a mere 6 seconds left on the clock before the cut off point of 30 hours, she was cheered over the finish line by hundreds of onlookers who were amazed by her incredible achievement.

When she crossed the line, she became the oldest person to ever complete the race, and seeing as we found the walk to work this morning tiring, we're seriously impressed by this.

Do you think you'd have it in you to take on a 100 mile run at any age?
