You start the clock, then you hitch; at the finish, you unhitch and feed before pressing STOP. The phone's end-of-run review knows how to remove those minutes — "Trim", before the run is sent. But on days when outings follow one another, nobody takes the time for the review: the run leaves with its hitching and unhitching in the track, in the moving time and in the distance. It is in the evening, at the computer, that you go back over the day.
What changes
On the page of an outing recorded by GPS on the phone, the owner and the handler find "Trim the run", next to "Correct the measurements" — when the website sees at least a minute of dead time at the start or at the finish.
The cards are the review's: "Remove nothing", "Keep the action", and "Remove only the hitching" when both ends can be trimmed. Each one says what it removes — "−2:01 before the start · −3:00 after the finish" — and shows its figures: moving time, distance, speed. A confirmation states the time removed and the distance before and after.
Once confirmed, the map, the speed graph, the splits and the stops start at the real departure and end at the finish. The distance, moving time and speed are those of the kept run, and they are what the dogs' load, the statistics, each dog's kilometres and the trails count. The page says so: "Trimmed (−2:01 before the start · −3:00 after the finish) — measured by GPS: 3.21 km · 13:31 · D+ 12 m".
What others see, and what they don't
Your kennel's members see the "Trimmed" note and the GPS measurement beside it.
A published outing keeps its public link: the public page shows the trimmed run, its track and its figures, without saying it was trimmed. It never shows the removed minutes or the original measurement. Nobody sees who trimmed it or when: the database keeps it, the screen doesn't show it.
What trimming doesn't do
Nothing is removed on its own: you pick the card.
The cut is final. The removed minutes leave the track for good, and a run is trimmed only once — where the phone's review, for its part, makes the run whole again as long as it is open.
The elevation gain and the top speed stay the GPS ones.
An outing whose figures were declared — "Correct the measurements" on the website, or the distance in the phone's review — is not trimmed. The other way round works: you trim, then declare a figure if the GPS was wrong somewhere else, and the page says both.
Not trimmed either: imported outings (GPX or Strava), outings entered by hand, races, whose official time is declared.
The phone receives the trimmed run — its track and its figures —, but does not say it was trimmed, and a run already sent is not trimmed there.
The choices that aren't obvious
The phone's rule, not another one. The website could have let you drag two handles on the map. It offers the review's cards, worked out with the same rule — a walking pace exceeded for thirty seconds, an end of at least a minute —: for the same outing, the phone and the website find the same start and the same finish.
The cut is final, and the confirmation says so. Keeping the removed minutes "just in case" meant keeping two tracks per outing. What is kept is the original figures, shown beside.
The elevation gain doesn't move. The phone computes it over every GPS point, with filters the website cannot redo on the stored track. And walking around the truck makes no climb.
The start isn't trimmed when the team changed along the way. Each change's kilometres would move back. Rather than shift them without saying so, the window says it, and the finish alone is trimmed if it can be.
A distance declared in the review isn't trimmed. Trimming by the track would erase the figure you typed.
