This used to be easy with the old UI. When the modern UI came along I couldn't figure it out so I used the option of switching to the old UI. But it seems that option is no longer available.
There must be a way to do this since it is one of the most common use cases. Really the only reason I own a Garmin device is to be able to publish stats like this so I can encourage others to try riding a bike once in a while.
Thanks,
Glen
