Duluth, MN (KDAL) - Organizers of the 38th running of Grandma’s Marathon—and the events surrounding the iconic Duluth event are looking back on what worked as they plan for next year. The marathon’s Bob Gustafson tells K-D-A-L News there will be a meeting of the minds in the forthcoming weeks involving the Grandma’s board, staff and key volunteers. Speaking of the volunteer muscle that help make the marathon run smooth, Gustafson says the prime running weather, faithful fans and volunteer help made this year the success it was. One change made this year that proved successful was a time change involving the half marathon. Gustafson says bumping the marathon earlier by a half-hour gave them more time to bus runners to the starting line. It also gave them extra time to clear the course and make conditions safer for runners.
