Restart Saved Session

Is it possible to restart a saved session. I started a long ride but did not complete the the full course. I had to restart my computer, so I saved my session. How do I restart at the point it was saved?

Is it even possible to ‘save a session’? I have never heard of this option. There is ‘save your ride’, but a ride is a closed item and you can’t just start up again where you left off, you would have to start an entirely new ride.
