Open a rowing .fit file — stroke rate, drag factor and no GPS
Rowing splits neatly into the machine’s numbers and the watch’s numbers, and a .fit file can carry either — which decides what the distance actually means.

The erg measures, the watch estimates
On an indoor rower, distance and pace come from the flywheel’s deceleration between strokes — a genuine physical measurement the erg computes. A watch recording the same session without a connection to the machine only sees your wrist, and estimates far more loosely. So a rowing .fit file’s distance is trustworthy when it came from the erg and approximate when it came from the wrist, and the file’s source fields tell you which.
Stroke rate and split, and what drag factor is not
A rowing file records stroke rate in strokes per minute and split as time per 500 metres — the two numbers rowers actually train to. Drag factor, where present, is a setting describing how much air the flywheel moves, not a measure of your effort; a higher drag is not a better workout, and reading it as a performance metric is a category error.
What you get from this page
This page reads your rowing file on your device and lists the stroke, split and rate fields, marking whether distance came from the machine or the wrist — so the number’s reliability is visible, not assumed.
