[BTS] Farthest playable turn on Marathon speed

[Civ for Worldbuilding]

I saw people playing hotseat games with 8, 10 civs, and playing as every civ trying to imagine their perspective on the events. I'm trying in the Earth map (18 civs) that is shipped with the game, and disabling every victory condition, on a Marathon match, and with two less civilizations. What I'm wondering is how far (in-game date) I could play the game without having issues such as long loading times or even save corrupting, and if I do a single player match with the same options, and a custom civ, and maybe the Dynamic Traits mod, how far could I go. The machine which runs Civ IV BtS has an Intel Core i5 3330 and 8GB RAM, Geforce GT 730, Debian 12.
Sorry if that was asked before, I never saw someone doing something similar in Civ4.
Thanks in advance

Stick it on AI autoplay and give it a few days.

I did that for a hotseat match, but with the original 18 civs Earth map. I was able to get to December, 2100. I could go further, but I was running out of time. Regarding loading times, when loading the game for the first time it took no less than 15 seconds, between turns, it took between 15 and 20 seconds in peacetime and between 20 and 30 seconds at war. I'll test the other configuration on the next weekend.
