    I have had similar suspicions that there is a difference between planned and tracked routes.  I have two hypotheses:

    • ascent & descent aren't properly figured into calculations
    • actual trails differ from mapped ones - i.e. the trails on the map are often missing the detailed bends / reroutes that you would encounter while actually on the trail.

    I have also noticed a discrepancy between what is tracked and what the phone's pedometer records.

    Both good hypothesis.  I put in a request to tech support to see what they had to say...

    Hey Jim,

    Yes, I see what you mean.  It looks like the route creation algorithm is underestimating the distance of the route.

    We're looking into this more and we plan to update our algorithm so that it produces more expected distance stats in situations like this.

    I don't have an ETA on when you can expect this update to happen, but we are working on it.

    Let me know if you have any other questions.
