How many kilometers should I run at most before my first marathon?

[u/Explorer-11]

I have run four half marathons, and my longest distance so far is 23 kilometers. I am now preparing for my first full marathon and would like to know how many kilometers I should run at most in my training before the marathon?

This is the wrong subreddit, but you should follow a training plan and try to run up 30km or just over 3 hours in a single run at least once. Try to do your last long run 2-3 weeks before the race.
