Best AI marathon training plan
A marathon plan is included below only when the app’s goal data says marathon is supported. Confirmed and uncertain are kept apart, because several vendors never list the distance.
The order is the directory’s euro coaching price, lowest first. It is not a ranking anyone paid for.

5K through marathon is plausible for a race platform, but the pages checked do not list those distances. Ultra is not listed either.
