What with one thing and another, I'm currently doing a lot of 14+ mile hikes, which takes a significant amount of time. I've read that the calorie estimates for hiking actually include BMR, which becomes a source of significant inaccuracy over time. As such, I have a few questions:
- Is this also true of tools other than MFP, such as https://caloriesburnedhq.com/calories-burned-hiking/
- Is there a good way of accounting for this error (eg 'figure out roughly what your BMR burn would have been over that period and subtract it')
- Am I overthinking this, given quite how many different sources of error there are likely to be when calculating calorie burn for long hikes?
