Looking for an old custom AOE2 scenario: Something along the lines of "Trials of a Champion"

I remembered back then when i got my installment of AOE2, there was this weird custom scenario that was present in my game. I forgot the exact name but it had something to do with “Trials”, “Champion”, or “Gladiator” in it. It was very weird because i will immediately lose whenever i tried starting the scenario.

If i remembered correctly, you start with a singular champion that is surrounded by a huge, dense clutter of random buildings. Everytime i lost, i would try and spectate the map but i cannot understand what the objective of the scenario was because i would only see a dense sea of randomly scattered buildings with seemingly no purpose.

I played this scenario way back when i was a kid, around the early 2000s. I don’t understand anything about aoe2 other than the basics so i don’t know what im supposed to do. If anyone could help me locate the exact scenario or what type of scenario it could be, that would be great.

Was it maybe the “El Cid (Brother Against Brother)” campaign?

Your description (singular Champion, surrounded by buildings) makes me think of an early 2000s multiplayer scenario named “Running Man”:
