If you don’t want to subscribe to Bee Plus to get access to auto trimming safety buffer, I’d suggest calling your goal something like three-mile-runs, give it a slope of one per day, and add a data point of 1 every time you run at least 3 miles.
You could apply the same strategy to your other two goals if you never want to accumulate buffer.
For your fat / sugar goals you could make them either do less or do more goals. I’d probably lean towards do-more, and register a data point of 1 each day I stayed within my limit.
If you’re hoping to use an auto data integration, you’ll need to upgrade your subscription to get the auto trim safety buffer feature, as the previous strategy won’t work if you’re entering raw data (number of miles run, x grams of fat, etc).
Hope that helps.
