Tracking easy runs

Hello all, 

I want to track basic easy runs with my fenix 7 but I can't seem to figure out how to do it. My routes vary so I usually don't know exactly how long they will be or how long it will take, so I don't want to build a run in the connect app based on any metric. I just want to start and end the run manually and have it track my stats. What is the best way to do this?

Thanks, 

Aaron
