How to reuse track

I would like to reuse an old track as a new hike. I cannot figure out how to do that.

Thanks for guidance.

I’d also like to know how to use an existing track for a trail marathon I’m doing. I have the track uploaded. How do I use this on the Marathon to stick to the trail?

Hello it is feasible but tricky
1 click on start to start tracking
2 click on the bottom menu
3 click on the route bottom
4 click on previous track option
5 choose among the tracks you have previously loaded
