Race events were derived from the local American Lung Association’s Lung Run, of which The South Bend Tribune was a supporting sponsor. As interest in the Lung Run waned, the Tribune became a sponsor of the Sunburst. Their hope was to create an event that would both benefit the local Lung Association and the community.  They aspired to provide a quality event that would both attract area residents and out-of-town participants.  The first race corresponded with Notre Dame Reunion weekend. The University of Notre Dame continues its support today. In 1991, Memorial Hospital joined The Tribune as a major sponsor. In 1992, WSBT TV and the WSBT Radio Group became major sponsors. In 2007, Sunburst registration grew to over 7,000 total participants in six events. 2008 marks the 25th anniversary running of Sunburst.
