LUBBOCK, Texas – On March 5th two men are participating in the 4x4x48 challenge. The 4x4x48 is a 48 hour physical running challenge that consists of running 4 miles, every 4 hours, for 48 hours. They chose to raise money to support Running 4 Heroes and their mission to provide grants that benefit first responders who are injured in the line of duty.
