12-Week Chickamauga Battlefield Marathon Training Plan

The 2026 Chickamauga Battlefield Marathon is scheduled for November 14, 2026, so the 12-week window opens around August 22, 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 the Chickamauga Battlefield Marathon on gently undulating roads, and run the second half of your long runs over the same ground as the first. The course asks for two things: tolerance for constant small grade changes, and the habit of running a second lap over terrain you have already covered once.

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.

It rolls rather than climbs. The Chickamauga Battlefield Marathon stays inside a 110 foot band between its lowest and highest points while accumulating about 940 feet of climbing, so the hills are numerous and short. The race calls them slightly rolling paved hills. Expect constant small grade changes and no real climb.

Yes. The time limit is 6.5 hours, the course runs on quiet paved roads inside a national military park, and the race says it suits first marathoners as well as runners chasing a qualifier. The catch is the second lap: after mile twelve the half marathon field leaves and the park gets very quiet.
