I use Strava on my Android phone to keep track of the distance for a ride on my adult trike.  How can I set the display to continuously display the mileage for that ride.  Right now, it displays the route.  I know the route I am on, I just want to know my distance as I am riding.  I am not concerned with time, speed, elevation, etc., just the current distance while on that particular ride.  Thank you.
