Belk was the largest individual philanthropists in track and field in North Carolina (and one of the largest in the U.S.), donating funds to construct 29 collegiate track and field facilities in North and South Carolina. Numerous high school athletes in North Carolina have benefitted from his kindness and generosity, as nearly all of the NCHSAA state championships over the past 25-30 years have been run on tracks funded by Belk. 

He was a volunteer member of the U.S. Olympic Committee for 45 years. In 2002 at the Winter Olympics in Salt Lake City he received the Olympic Order which is the highest honor a volunteer can receive.  

Some of the 29 tracks that were built by Belk: Appalachian State University, Campbell University, Davidson College, Elon University, Furman University, High Point University, Johnson C. Smith University, Lenoir-Rhyne University, Livingstone College, University of North Carolina at Chapel Hill, N.C. A&T State University, UNC Charlotte, UNC Pembroke, Queens University, Wingate University and Winthrop University, and at least 13 more.
