The Great Lakes Marathon Series is a collaboration of 24 marathons that take place along the 5 Great Lakes. The goal of this series is to invite the running world to come and enjoy the unique beauty of each race, while simultaneously raising awareness of conservation and restoration efforts of the Great Lakes as well as focusing on the Great Lakes ecosystem and economies. Please note that the Great Lakes Marathon Series can only be accomplished by running the 26.2 mile distances offered by each event. Races run at any other distance will not count towards the completion of the race series.


The Great Lakes Marathon Series is for runners who are interested in experiencing a variety of marathons along the Great Lakes, while at the same time making a positive impact on the eco-system of the Great Lakes Basin.

The series is for fast and slow runners alike with individual prizes being awarded based on the number of Great Lakes races you complete throughout your running career. We will award prizes at benchmarks along the way, with a grand prize for those runners dedicated enough to finish all 24 great lakes marathons in their lifetime.

The Great Lakes Marathon Series organizers invite you to sign up for the series and log your miles by CLICKING HERE. Through this site you will be able to upload each of your finishing times and track your progress.

In addition to the individual commitment from each member in the series, we have partnered with the Alliance for the Great Lakes, a 4-Star rated non-profit devoted to protecting and restoring the Great Lakes.



We are using a Greenlayer, Helium E2 shirt with a simple GLMS logo design on the front and the Alliance for the Great Lakes logo on the back. For every training shirt sold, we will donate $1 to the Alliance for the Great Lakes! Currently there is a small run in the works. Please download the PDF order form HERE. If you have any questions about the training shirts please email info@grandmasmarathon.com
