This route runs through / across all 4 counties in the Rio Grande Valley, Star County, Hidalgo County, Willacy County, and Cameron County. I am doing this run for a Local charity to raise funds for our local Boys and Girls Club. the Route runs through the outer county lines and mostly though back roads, a small section is dirt but the rest about 75% is paved. I plan to run this all in one "go" 115 miles. This run is supported.
