The WBC Unity Green Belt Amateur Challenge will be August 26 and 27 in Las Vegas.
The two-day event will showcase some of the best boxers in the country including Grand Junction's Masai Rasheed, Efren Vega, and Alejandro and Jaime Sanchez.
All four fighters will be representing the Rival Boxing Gym.
"It's good competition, over there," 13-year-old Alejandro says. "They're the best of the best and that's really what I'm excited about. Fighting someone better."
This event will lead to another Green Belt challenge in October.
"It'd be a good feeling to the "W" and win," 12-year-old Jaime says. "It would just mean the world."
The Grand Junction fighters will be competing the same weekend as Floyd Mayweather's fight with Conor McGregor.
"I already know there's going to be fans and that whole Las Vegas strip is going to be really busy. so hopefully it'll attract more of an audience to come watch us fight and then go watch those big guys fight in the big leagues," 22-year-old Masai Rasheed says.
