FORT COLLINS, Colo. – A visually impaired man from Fort Collins is looking to break a world record by being the first blind runner to trek up and down Machu Picchu within 24 hours’ time.

The 25 mile stretch is difficult, but Dan Berlin has been preparing for it.

“I started running about six or seven years ago,” Berlin said.

Berlin spends most of his time running around Fort Collins. Although he can’t see how beautiful the area is, he appreciates it in other ways.

“For me a lot of the beauty is the sound, the crisp fall air, the sound of the crunching gravel,” he said.

Berlin is leaving for Machu Picchu on Friday. On Thursday, he was doing one last practice run with his buddy Scott Jurek in Boulder.

Jurek is an ultra-marathoner who just finished the 2,000+ mile Appalachian Trail’s ‘Thru-Hike’ faster than anyone else in history.

“He’s [Berlin] the real rock star though!” Jurek said of his pal.

Berlin is excited for the adventure and challenge. But a tad bit nervous, also.

“The biggest pressure I have going in to this run is we have to go through the last gate to get to Machu Picchu by 4 p.m.,” he said.
