Official app for Grandma’s Marathon Weekend
June 21-22, 2019 in Duluth, MN
This app contains important event information for Grandma's Marathon, the Garry Bjorklund Half Marathon, and the William A. Irvin 5K. This app allows you to track marathon and half marathon participants in real time during the event. Please note, due to some remote locations along the course live-tracking may not always be available.
This app is powered by MYLAPS.
This app may use your location even when it isn’t open, which can decrease device battery life.
