4-Day Green Bay Marathon Training Plan

The 2027 Green Bay Marathon is scheduled for May 16, 2027, so the 18-week window opens around January 10, 2027. Weeks one through 17 keep the normal weekly rhythm and Sunday long run; only the final race week shifts to the event's actual weekday. If that date has already passed, do not compress 18 weeks of mileage into a shorter window.

Do several Green Bay Marathon long runs on uninterrupted flat ground. With few terrain changes to reset your stride, steady pacing and late-run form matter more than hill speed. Train for the EPIC Marathon by rehearsing goal pace in long, unbroken blocks, because a flat course gives you nothing to hide behind. On rolling terrain, every hill forces a change in stride and a moment of relief. Here you will hold one cadence for hours, so the failure mode is not blown quads at mile 19 but the slow drift where your form degrades and the pace goes with it.

Four run days can be enough when 15 miles in week one is not a sudden jump and you can protect the long run most weeks. This schedule builds to a 40-mile peak and a 20-mile long run. A runner chasing an aggressive time or already supporting more volume may fit a higher-mileage plan better.

The organizer describes the courses as fast and flat, running through Ashwaubenon, Green Bay, Allouez and the Brown County trail system. No elevation profile or gain figure is published, so treat flat as their description rather than a measured number. Train for sustained goal pace with no hills to break up your stride.

Both on Cormier Road, outside the EPIC Event Center in Ashwaubenon, just off Holmgren Way near Lambeau Field. Every distance in the festival uses the same start and finish, and the marathon goes off at 7:00 a.m. alongside the half marathon and the relays, so race morning logistics are simple.
