His trip started in California on March 21, 2013.
Seehorn's long beard has become a trademark. He has not shaved it since 2011.
Recently, he made a stop in the Quad Cities. Christine Lum of Rock Island was out for a walk when she saw Seehorn's two-seat baby stroller covered with rain gear and signs.
"I asked him if he needed a place to stay," said Lum.
Seehorn accepted and has been resting before he continues his journey east.
He has stayed at several people's homes along his journey.
"Anytime I can get a warm place to stay and a hot meal, I will take it," Seehorn said.
But this run has become a test of not only his physical limits, but his mental and spiritual endurance.
"It's been a mental, spiritual, and emotional trip with being away from home for so long," said Seehorn.
Seehorn is from Athens, Georgia. He comes from a background of environmental teachers and biologists.
Seehorn graduated from the University of Georgia in 2008 with a Bachelor's Degree in Wildlife Biology. In 2011, he graduated with his Master's Degree in Natural Resources with a concentration in fisheries.
After his cross-country journey, he plans to start a business.
"When I get back to pursuing a career, I am going to apply the determination and diligence that I applied during this trip to my business," said Seehorn.
But Seehorn says the one thing that will stand out to him after his trip is done, is meeting people from all different cultures along his path.
"It's been fun seeing people's personal lives and seeing how it relates to my life and how I was raised," Seehorn said.
Seehorn planned to lace up his shoes and continue his run eastward on Tuesday, November 12, 2013.
