SALT LAKE CITY — On Oct. 18, 2020, the trail and ultrarunning community lost one of its own. On April 10, 2021, runners took to the red rock trails surrounding Zion National Park to race upward of 100 miles in his memory. Matt Gunn who KSL.com connected with in 2015 for an article on his Ultra Adventures race series, died by suicide after what those closest to him describe as some very deep sadness. That sadness, however, was long overshadowed by what he brought to those he came in contact with — and it was the legacy and impact that Gunn left that caused hundreds of people to take to the trails for the recent Zion Ultras event that he created.
