Garmin, COROS, and Suunto can all produce a GPX file from an outdoor activity. Choose the workout or activity you actually recorded—not a course or route you planned before the trip.

Before you export
Activity and route are not the same file.
Choose this
Activity, workout, training, or track
Recorded by the watch during the outing
Has a start time and duration
Can contain GPS timestamps for matching
Avoid this
Route, course, or navigation plan
Created before the outing
May contain location only
Does not prove when you reached each point
Suunto documents the distinction directly.
A workout GPX includes location and time, while a route GPX contains location information for navigation. LensPin needs the recorded workout type.

No conversion needed
Do not redraw, simplify, or merge the activity unless it is genuinely broken; conversion can remove time or segment boundaries.
One quick verification is enough.
Open the file in LensPin and confirm that it reports timed track points covering the trip. If not, return to the activity platform and check that you exported the workout rather than a course.
