Cellcom Green Bay Marathon

 
The Cellcom Green Bay Marathon is an annual marathon that takes place in the streets of Green Bay, with all events making their way through the iconic Lambeau Field. Approximately 7,500 runners from all over the globe compete in this world-class event each year. If you’re not quite ready for 26.2 miles, there are other events to choose from. There is a half marathon, a marathon and half marathon relay and a 5K run. 
 
The marathon is a Boston Marathon qualifier, which means the event is sanctioned by USA Track Field and the course is certified. The race typically takes place the third weekend in May, and the average temperature in Green Bay that time of year ranges from a low of 45 degrees Fahrenheit to a high of 67 degrees Fahrenheit.
