Although the filtered press conference was to be expected, the interactive map LE have provided is interesting.
Truck stop, car wash, and 385th avenue are possible areas where her FitBit/iPhone data traveled through.
She must have ran through the town past the car wash heading west on East 2nd street which eventually turns to US-6.
Then she turns right on 385th avenue, which I am guessing was final stretch of her run on the way back to the bf's house on W. Des Moines St.
The FitBit/iPhone data must have left a trace near here, perhaps on the way to Guersney and onward. Could be a truck driver or the perp just drove past here.
