Hi, and thanks for your reply. I don't believe my code has any issues with adding the workout nor adding the distance into the Walking + Running Distance portion of the Health.app. I can browse the data in those sections of the Health.app and see all of the data from my app. However, if I go to Browse > Activity > Walking + Running Distance and tap on the bar in the chart for the current day the total distance (miles in my case) for the current day does not include the distance that I've added. If I scroll to the bottom of this section and select Show All Data I can see the data from my application. I have also gone in to the Data Sources & Access section and moved my app to the top of the list of Data Sources with no luck. So to summarize, the workout data and distance data from my app are appearing correctly in Health.app, but the distance reported by my app is not being used in the total for the day as reported by the chart at the top of the Walking + Running Distance section.
