Finishing the Leadville 100 is a challenge. Not only is there the physical effort of getting up and down the mountain trails, but the air is also thin above 10,000 feet. 

Johnathan Prosser lives in the relatively low elevation of Kansas. And his first attempt at a mountain trail race ended with a DNF. He had a goal to run the Leadville 100 and he decided he needed a better strategy if he was going to be successful. 

He found a coach and followed a solid training plan. He also allowed some days before the race to get into the mountains and adapt to the altitude. 

And his coach gave him a great strategy to follow during his race. "Don't think about time. Focus on managing your energy."
