4-Day Detroit Free Press Marathon Training Plan

Detroit, MIOctober 17, 2027

Four runs per week for 18 weeks: two easy runs, one midweek aerobic run, and one long run. The schedule stays fixed; the guidance below shows how to choose terrain, rehearse conditions, and prepare for the Detroit Free Press Marathon course.

The Detroit Free Press Marathon requires a passport. About two miles in you climb onto the Ambassador Bridge into Canada, run the Windsor riverfront, then come back to the United States underneath the river through the Detroit-Windsor Tunnel. Border documents go on the packing list alongside your shoes.

Your complete Detroit Free Press Marathon schedule

The 18-week window opens around June 13, 2027. Weeks one through 17 keep the normal Tuesday, Wednesday, Thursday, and Sunday rhythm. Only race week moves so the marathon lands on its actual weekday. If the window has passed, do not skip ahead or cram missed mileage into the time left.

Open any week to see all seven days. Week 1 is open to start.

This free plan is complete, fixed, and ready to use.

It begins at 15 miles per week, peaks at 40, and asks you to manage schedule changes and missed training yourself.

A Stride plan ranks from your running, then dates to race day.

Current mileage, recent longest run, marathon experience, goal, and available days decide which plans rank first.

How to use this plan for Detroit Free Press Marathon

The mileage builds your engine. Your long-run route, pacing, fueling, and clothing rehearsals make that fitness specific to this race.

How to train for the Detroit Free Press Marathon

Two Detroit specific sessions matter. First, put a climb in the first fifteen minutes of some long runs, so the Ambassador Bridge at mile two doesn't cost you an effort spike that you pay for at mile 22. Second, practice running a full mile purely by feel, because your watch goes dark in the tunnel.

The rest is even pacing work on flat ground. With a net change of nine feet across the marathon there's no terrain to recover on and no descent to bank. Long runs at goal pace finished with a negative split teach the exact skill this course rewards.

Plan for a slow patch on the bridge itself. The race asks runners not to stop for photos and it still bunches up, so budget a few seconds there and resist the urge to make them back over the following mile.

Keep the plan honest. This free schedule contains no speedwork. Apply the course guidance through route choice and race rehearsal without turning easy days into extra workouts. If your goal calls for marathon-pace work, compare it with First Marathon Plus.

Match the terrain

Do several Detroit Free Press 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.

Rehearse race morning

Mid October in Detroit is close to ideal for racing: a typical start near 47F with humidity around 79%, an average high of 58F, and a light southwesterly. The problem isn't the running, it's the waiting. You'll be standing near the river at dawn in the high 40s, so bring throwaway layers and do a few long runs in cold morning air so your first three miles don't start hot just to warm up.

Prepare for the hard part

There's no famous wall here. The race gets hard after mile 20, when a course with only 388 feet of total climb stops offering any change of rhythm and you have to hold a single effort all the way to Campus Martius.

Check the starting line before you commit.

Beginner-friendly does not mean couch-to-marathon. Week one asks for four runs, 15 total miles, and a six-mile long run.

Fifteen miles in week one is close to the volume you already handle.
You can protect four run days most weeks, including a weekend long run.
Your priority is a steady first-marathon build without speedwork.
You can start around June 13, 2027 without forcing the early weeks.

Detroit Free Press Marathon questions, answered.

When should I start this 18-week Detroit Free Press Marathon plan?

The 2027 Detroit Free Press Marathon is scheduled for October 17, 2027, so the 18-week window opens around June 13, 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.

How should I adapt the four-day plan for the Detroit Free Press Marathon course?

Do several Detroit Free Press 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. Two Detroit specific sessions matter. First, put a climb in the first fifteen minutes of some long runs, so the Ambassador Bridge at mile two doesn't cost you an effort spike that you pay for at mile 22. Second, practice running a full mile purely by feel, because your watch goes dark in the tunnel.

Is four days a week enough to train for the Detroit Free Press Marathon?

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.

Do you need a passport for the Detroit Free Press Marathon?

Yes. The marathon crosses into Canada, so every runner needs a valid passport, a WHTI compliant document, or an enhanced driver's license from Michigan, Minnesota, New York, Vermont or Washington. The race also warns that past convictions including OWI or DUI can make a runner inadmissible to Canada without a special permit.

Is the Detroit Free Press Marathon flat?

Yes. The course gains 388 feet and loses 397 across 26.2 miles, a net drop of nine feet, with everything between 538 and 740 feet of elevation. The only meaningful climb is the Ambassador Bridge about two miles in. After that the race becomes an exercise in holding one steady effort.
