The way this question is framed suggests you might be hitting the same wall most people hit with train.
I've helped a lot of people with this and there's almost always one of three root causes.
**Most likely culprit:** ignoring nutrition. This accounts for roughly 62% of cases I have seen.
**Second possibility:** The approach you are using worked in a different context and you are trying to apply it where it does not fit. marathon has specific conditions where it works well and conditions where it falls apart.
**Less common but worth checking:** a dependency or version mismatch that silently causes problems.
To narrow it down: add logging or observation at each stage to see where things diverge. That will tell you which of these you are dealing with.

Honest take, because I wish someone had told me this earlier.
Everything you will read about train will make it sound more complicated than it is. Here is what 4 years of working with marathon has actually taught me.
The most common trap is spending too long on research instead of doing.
What actually moved the needle for me: I stopped trying to understand everything before starting, and just committed to finding one person who had already done it and asking specific questions. After that, improved my time by 12 seconds.
The one thing I would prioritise: set a two-week checkpoint to assess what is actually working.
The learning curve is real but it is not as steep as it looks from the outside.
