12-Week Fort Worth Marathon Training Plan

The 2026 Fort Worth Marathon is scheduled for November 8, 2026, so the 12-week window opens around August 16, 2026. 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 Fort Worth by building durability against repetition rather than against hills. Run your long efforts on flat greenway or riverside pavement at close to goal pace, and grow the portion of each long run held at marathon effort instead of adding hill work you'll never use on race day.

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.

Yes. The course stays inside roughly a 100-foot elevation band, with about 544 feet of total climbing and 552 feet of descent, and it finishes within 8 feet of the start. The organizers call it a fast course. The training consequence is repetition: nothing on the route changes your stride for you.

Small. There were 472 finishers in 2025, up from 365 in 2024 and 179 in 2023. It sits inside a running festival now in its 20th year that also runs shorter distances the same morning. Expect a quiet course, thin spectator support and stretches where you're running alone.
