PHOENIX (KSAZ) - The cadets run 104 miles a day; each person runs between 15-20 miles of that distance.
The run will take them fro Sturgis, South Dakota, through seven states where they will finish on the Santa Monica Pier in Los Angeles.
FOX 10 caught up with them as they reached the Arizona State Capitol.
It may seem crazy for most of us to go running through 100 degrees plus weather, but not to these guys. Eight ROTC cadets are running across the country, helping to raise money for veterans programs.
"We wanted to do something that was difficult. A lot of people do not exactly know the difficulties people in the military go through on a daily basis, what veterans go through when they come back home and attempt to reintegrate into civilian society," said Matt Rojas.
"We feel there're a lot of organizations that exist to help veterans re-integrate, but not necessarily educating civilians on their role in helping that happen," said Micah Petersen.
The cadets started their run Monday at 5:30 a.m. in Prescott, they reached the Arizona State Capitol around 4 in the afternoon, making sure to take precautions in the Arizona heat.
"One, obviously we stay hydrated, we have a ton of coolers, we're constantly filling up water. We have cool rags to put on our wrists and on our neck," said Rojas.
But these cadets point out they're not the story, they're just trying to raise awareness and funds for military veterans and service members.
"We're just doing our little part to help people better understand what our veterans, and what our military service members go through every day," said Rojas.
So far the cadets have raised $8,000, if you'd like to know what the name Riveresco is, it means "to grow strong again."
