During the 2017 Superior Spring Trail Race, we lost a member of our trail running community. Jon Mathson, 41, of Eagan, Minnesota, collapsed on the trail between Moose Mountain and Mystery Mountain while running the 25KM race. The official cause of death has not yet been determined. Jon was a three-time finisher of the Superior 25KM race, loved trail running and mountain biking with friends, and was an avid birder. Jon taught Earth Science and Chemistry at Eagan High School and was revered by his students and co-workers alike. Jon is survived by his wife, Becky, and two-year-old son, Dylan. Please join with us in holding Jon’s wife and son in your thoughts and prayers in the days and weeks to come. A “Go Fund Me” campaign has been set up for Jon’s wife and son; please consider making a donation. https://www.gofundme.com/jon-mathson-memorial-fund
