Displaying total running distance as watch face complication

A long time ago I was using the Nike app for my runs. A highlight was the complication that very simply showed how many KMs (or miles) I’ve so far ran per month to show my progress and keep me motivated. It was super good for me as I had a goal to run a total of 100KM minimum every month.

For many reasons I have changed to Apple’s Workouts app for my runs. The biggest thing I’ve lost is no way to do the same thing as a watch face complication to show total running distance per month (or weekly would be OK too). I’ve not figured out how to do it.

Does anyone know how to set this up as a complication for Workouts? One that shows my total running distance for a defined period… not just the Workouts icon as a shortcut link.
