Multiple files supported — they'll be processed together and downloaded as a ZIP.
Basic
Sport
Generic
Road
Mountain
Cyclocross
Ebike
Maps to FIT Sport / SubSport. Affects how Garmin Connect / Strava categorizes the activity.
Start Time Override (CET/CEST, optional)
Useful when your FIT file has incorrect start time. Leave empty to keep original.
Cleanup & gaps
Minimum gap (seconds)
Leave empty to skip gap compression.
Maximum gap to compress (minutes)
Longer gaps stay as recorded (e.g. lunch break). Empty = unlimited.
Remove stopped/slow records
Off
Drop < 2 km/h
Drop < 4 km/h
Drop < 6 km/h
Drop < 8 km/h
Drop < 10 km/h
Drops records below threshold AND cadence < 40. Warning: on ebike this may drop power-assist segments and inflate average speed.
Smooth Metrics (window in seconds)
Smooth heart rate and speed. Leave empty to keep originals.
Trim & sensors
Trim start (s)
Drop first N seconds.
Trim end (s)
Drop last N seconds.
Strip sensor data
GPS
HR
Power
Cadence
Temp
Drop sensor fields (broken sensor / privacy).
Power & e-bike
Power scale (×)
Calibrate a low-reading meter (e.g. Bosch e-bike ×1.15). 1 = unchanged.
Power offset (W)
Added after scaling.
FTP (W)
Enables Intensity Factor & TSS in the file.
Protect training metrics (e-bike)
Strips power so a torque-sensor estimate can't drag down Garmin VO2max / training load. Overrides the scale/offset above.
Advanced
Add synthetic pauses at start/end
Appends 1-10 minutes of stationary records before the first and after the last real record.
Merge all into one activity
Concatenate the files chronologically into a single activity (e.g. resumed ride on another device). Distances are stitched cumulatively.
