Not that I have ever seen or heard of. The native Workout app holds your data hostage with no meaningful way to export it. Apple has no provision for any of the standard (fit, gpx, tcx, etc.) files that workout tools use. However, you can use one of the many iPhone based apps on the AW to capture a workout, like Runkeeper, Map My Run, Strava, etc., and those can export from their mobile and web apps.
