A free browser tool combines split FIT workout recordings into one downloadable activity.

Landing page captured for the 2026-10-24 issue.

For: Runners and cyclists with split FIT recordings
Worth noticing: It advises deleting the first original Strava recording before upload to avoid a duplicate rejection.

Field notes

The workflow accepts FIT files only, sorts multiple inputs by start time, and produces a merged FIT download. The page says the gap between recordings remains a pause: elapsed time includes it, while moving time does not. It also advises deleting the first original Strava recording before uploading the merged result, because Strava may otherwise reject it as a duplicate.
