Is Marathon a good day trip from Athens?

I've been planning an itinerary for my upcoming trip to Athens, and I've always been fascinated by the historical significance of Marathon. Considering its role in ancient history and the famous battle that took place there, it seems like a place that might be worth a visit.

However, I'm on the fence about dedicating a whole day trip to Marathon. From what I understand, it isn’t too far from Athens, but I'm trying to weigh up whether the experience is worthy compared to spending that time exploring more within the city itself.

Has anyone made the day trip to Marathon from Athens? Was it an enriching experience, and what are the can't-miss sights? Is the archeological site/museum there engaging enough for a history buff? Also, how about the logistics – is it easy to get to by public transport, or would you suggest renting a car or going with a tour?

I am just trying to decide if it's worth it, or if I should plan to stay overnight. Thanks!

I haven't done it, but I heard it is well worth it. The individuals I know who went were history buffs, and one was an avid marathon runner, so they both got something out of it and found it was worth spending the day there.

I haven't done it yet either, but this is on my list to do. I ran a marathon once, it would be fun to see where it all originated.
