Find a route - is it possible?

Hi there
I need your help - I would like to ask you if it is possible to choose an activitya(e.g.running) then set a distance and let the device find some track/route suggestions?

If so how can I do it?

Sorry if the question is 'too easy' but I am new to Garmin and the amount of different options os overwhelming to me right now

Regards
?
