Summary:
During my usual walk (about 6.3 kilometers) I saw the distance suddenly jump to 24,05 km. I was walking with my iPhone in my back pocket listening to a podcast.

Steps to Reproduce:
about 8124, according to a later workout, though I don't know what combination of factors lead to this jump. 

Expected Results:
The same round - done a day afterwards - yielded these expected results:

- outdoor walk
- 272 active calories outdoor walk,
- total time 1:07:12
6.3 kilometers


Actual Results:
- outdoor walk
- 289 active calories
- total time 1:17:20, 
- total distance 25.99 kilometers  <- totally insane

Configuration:
I suspect that you'd get a result like this if Core Location loses precision dramatically. There should be some sanity checking where the distance travelled is totally unrealistic compared to mode of locomotion, i.e. I could not possibly have walked 26 kilometers but only used 289 Calories and also not in 77 minutes.
