Walk - Hill Workout, Walk verses Hike - Hills - Hiking, Light or No Pack

I have a 5 mile route around my rural hillside home that includes a lot of up and down with some 800 feet of elevation change. Most of the route is gravel road and I generally do it about an hour and a half. Under what activity should I log it? The two that seem most relevant are Walk - Hill Workout, Walk or Hike - Hills - Hiking, Light or No Pack. There seems to be little or no difference in the descriptions, but there is a big difference in the calories reported to be burned. For my stats (age, weight, ...) the Walk - Hill Workout burns 463 calories, while the Hike - Hills, Light or No Pack burns 893 calories.

BTW, all of the Walk and Run variations report 463 calories burned regardless of type of walk or run unless I am pushing a stroller, and all of the hiking variations report 893 calories burned regardless of type unless I am rock climbing or carrying a pack. The hills don't seem to matter in the calorie burn calculation, but they sure do matter in amount of work/effort expended. My fitbit credits me with over 70 flights of stairs for the route.
