Today I exported my running exercise to tcx and gpx and imported it to a site that calculated the distance. It turned out that I was running a longer distance than my watch showed. I know about (re-)calibrating the watch, but the description tells me to start a Walking or Running exercise in the default Apple Watch Work-out app. Would re-calibration also work when I use Workoutdoors or do I really have to use the default Work-out app for the re-calibration?
