In 2012, Jared Campbell decided to run up and down Salt Lake City’s Grandeur Peak for 24 hours, to raise money for air quality advocacy work. The following year, a few friends joined in. The next year: even more. After 11 years, Campbell’s solo project has morphed into Running Up For Air: a worldwide movement with dozens of races, hundreds of runners and tens of thousands of dollars raised around the globe. This is a story about how running builds community that can jump-start change far beyond the trails.
