12-Week Kentucky Derby Festival Marathon Training Plan

The 2027 Kentucky Derby Festival Marathon is scheduled for April 24, 2027, so the 12-week window opens around January 30, 2027. Treat that as the outside edge of the window, then line week one up with the plan's normal weekly rhythm.

Use this window when your recent training is steady and the opening week will not be a mileage jump. If you are returning after a long break, twelve weeks is too little room to rebuild and peak at the same time. The course does not change the opening load you can handle, so choose from your current mileage and recent longest run before adding race-specific terrain.

Course-specific work starts early in a 12-week build. Put the race's terrain and expected conditions into long runs once the opening weeks feel controlled, without adding extra hard days. Train for the Kentucky Derby Festival Marathon on flat ground with one deliberate hill loop planted in the middle of your long runs. That is the shape of the race: roughly 500 feet of total climbing, most of it concentrated in Iroquois Park, then flat miles home on legs that have already been worked.

Do not double weeks or cram missed mileage into the remaining calendar. Use your current mileage, recent longest run, experience, goal, and available days to choose a plan that can enter at an appropriate point while preserving the taper.

Mostly no. The Kentucky Derby Festival Marathon is flat through downtown Louisville and the South End, with about 500 feet of total climbing and roughly 150 feet between its lowest and highest points. Nearly all of that sits in Iroquois Park, which gives you one real climb in an otherwise level race.

Yes. The route passes Churchill Downs, home of the Kentucky Derby, as part of the South End section that also takes in Southern Parkway and Iroquois Park. The event is run as part of the Kentucky Derby Festival, which is what puts the course on that ground in the first place.
