Apple health insists on combining running and walking distances. This annoying for true runners and it would be great to see this modified so runs and running distances can be tracked and summed by themselves.
Apple Watch Ultra
Are you running and walking (i.e. Jeffing) in the same workout? That cannot be separated.
Separate workouts display separately on the Activity/Fitness app
I know of no app which will automatically add up the runs and add up the walks for weekly or monthly subtotals.
