Retracing footprints of saved track log

Hi Team!
I'm making an assumption this is possible, but can't find a way to get it happening.
If I have a saved track log, how can I show that trail overlayed on the active map screen.
My use case here is, I travel through a complex maze of tracks and find my way through, call it dumb luck. 2 years later I want to follow the same route. So I'd pop open the track log, positions overlayed on main topographic map and use my live position arrow to navigate the saved path.

From what I can tell, I have the tracklog saved, have the off-line maps saved which I can drive around with, showing my current position, can view both independently, but struggling to bring them together.

Anyone know how to solve what I am assuming is my own incompetence, because I'm thinking this should be dead easy.

Cheers.
