Some people make a change in little steps. Dean Karnazes isn't one of those people. He runs towards change...literally.
On Thursday (June 21) Karnazes hopes to break the Guinness World Records mark for the longest treadmill run in 24 hours. The current record is 153.76 miles.
He's making his attempt for the whole world to see above Times Square in New York City.
"This has got to be the craziest thing that I've ever done in my whole life. But, I hope, you know, hopefully I can issue a wake up call to some people to get off the couch and get more active," said Karnazes.
Karnazes said he had his own very abrupt wake-up call after a milestone birthday a few years ago.
"I walked out of a bar on my 30th birthday and wasn't a runner and I just decided that night I was going reclaim my health and run 30 miles. So I set a course off into the night and 8 hours later I covered 30 miles. Wasn't pretty--it was some blistering and chaffing involved - but I made it 30 miles and I just kept going from there."
Since that night Karnazes has kept up the pace.
He has completed 50 marathons in 50 days in 50 states.
He's run across Death Valley in the middle of the summer, he's run to the South Pole and once ran 350 miles continuously.
