What is GOTOES?
GOTOES is a set of browser utilities for the moment your data ends up in more than one place. Your bike computer recorded the route but the heart rate strap was paired to your watch. The power meter dropped out for ten minutes. The FIT file is corrupt and Strava rejects it. A race went through a tunnel and the GPS came out the other side in a different postcode. Each tool does one of those repairs on GOTOES's own server, with nothing to install, and hands you a file to upload.
The flagship is the merger, and its description is the clearest statement of the whole site's purpose: it combines heart rate, power, position, cadence, elevation, distance and temperature from separate files into one, and repairs corrupted FIT files while it is at it. Feed it up to twenty files and it works out how to lay their streams on a single timeline. With a GOTOES account you can pull the source activities straight from Strava rather than exporting them by hand.
It is not an analytics site and it does not keep a copy of your training. There is no dashboard of your season, no charts, no social feed. It is closer to a workshop bench: you bring a broken file, you leave with a fixed one. The site has been running since 2015, it is maintained by one person, and the changelog is the best evidence of that. The merger is on version 43.8, dated September 29, 2026, and recent entries cover catching subtler GPS jumps, Google Earth compatibility for KML exports, and splitting multisport files by sport.
Key Features
Merge, trim and repair FIT, GPX, TCX or CSV
The core tool. It combines heart rate, power, position, cadence, elevation, distance and temperature across files, so a route from your head unit and a heart rate trace from your watch become one activity. It also repairs corrupt FIT files that upload as errors, includes a point editor that flags spurious GPS spikes on a map and deletes them in bulk, and can trim the start and end of a file, or trim a multisport file down to one sport. It exports GPX or TCX (and XLSX for the raw numbers). Free accounts get 20 files per job at 14MB each and 19MB total; donors get 28MB and 38MB.
Split one file into pieces
Split GPS Files, added on September 28, 2026, cuts one FIT, TCX or GPX activity into segments at points you place on the map or charts. You name each piece, untick any you don't want, and download them as GPX or TCX (FIT for donors), singly or as a ZIP, with laps trimmed at each cut and totals recalculated. Kept pieces can go straight into the merger. One file per job, up to 14MB (28MB for donors).
Race Repair, for when the GPS gave up
Give it exactly two files, your original activity with its heart rate and cadence, plus a course file for the event, and it builds a synthetic position track that fits your real start and finish times. Then it hands you off to the merger to combine the streams. This is the fix for a marathon where the watch lost signal among tall buildings but you still have the official route.
Timestamps and time shifting
Creates timestamps on files that have none, shifts an activity to the correct time, and rebuilds missing sections. Useful for indoor and virtual rides, where Strava cannot infer a timezone from GPS coordinates at all.
Shrink a FIT file under Strava's limit
Keeps every second, fifth, tenth or twentieth record, for reductions of 50 to 95 percent. The use case is a very long or very high-frequency recording that Strava or Garmin refuses to accept.
Garmin Connect to Strava, activity by activity
The standing Garmin-to-Strava auto-sync is all or nothing. This tool lets you pick which activities to send, which is how you keep a treadmill test or a lawn-mowing "ride" out of your Strava feed. It needs a GOTOES account with Garmin connected, and it is a donor feature.
Upload to Strava by email
Email a FIT, GPX or TCX file as an attachment from your registered address and it lands in your Strava account, with the subject line becoming the activity title. You can connect up to two Strava accounts and send to both at once. Strava retired its own email uploader years ago.
Bulk upload from a spreadsheet
Fill in a Google Sheets or Excel template and it creates the manual activities in Strava in batch. This is the tool for backfilling years of logbook entries, and the sport names have dropdown validation because they have to match Strava's exactly.
Inspect and convert
A FIT file viewer for reading the actual fields and diagnosing why something is wrong, a FIT-to-CSV converter for pulling record streams into a spreadsheet, and a waypoint filter that strips a POI file down to the points near your course.
Who It's For
- Anyone running two devices, where the route lives on one and the sensor data on the other
- Racers whose GPS died mid-event but who have the official course file
- Garmin users who want to choose what reaches Strava instead of syncing everything
- People backfilling history, whether from a spreadsheet of old logbook entries or a pile of files
- Anyone Strava has rejected, with a corrupt FIT or a file over the size limit
Is GOTOES free?
Mostly. Nearly all the tools work without paying, and merging, repairing and exporting GPX or TCX are free. The site runs ads and shows a nag screen, and there is a free way to remove both: opt into the "Help Others Repair Their Tracks" setting. Some features need a donation, including the Garmin-to-Strava tool. Three dollars or more removes the ads and nag screen for a year, and ten dollars or more turns on every feature for a year and doubles the upload limits across every tool. On the merger that means 28MB per file and 38MB total; the shrinker goes from 25MB to 50MB. Patreon from three dollars a month covers the lot for as long as you subscribe. Donor benefits are digital and the site says payments are non-refundable once access is granted.
Do I need an account to use the GOTOES Strava tools?
For some of them. Dropping a file into the merger, the shrinker, the FIT viewer or the FIT-to-CSV converter needs no login. An account is required wherever GOTOES has to talk to Strava or Garmin on your behalf: importing activities directly from Strava into a tool, the email uploader, the spreadsheet bulk uploader, and the Garmin-to-Strava transfer. The Garmin-to-Strava transfer is also a donor feature. You create a GOTOES account with an email address, then authorise Strava from your dashboard. Up to two Strava accounts can be connected at once.
What can the GOTOES file merger actually combine?
Heart rate, power, position, cadence, elevation, distance and temperature, in its own words. The typical job is a route recorded by a bike computer plus a heart rate trace from a watch, merged into one activity with both. It accepts FIT, GPX, TCX and CSV, up to twenty files at a time, and also repairs corrupted FIT files that Strava rejects outright. There is a point editor that detects likely GPS spikes, marks them on the map and lets you delete all the flagged points at once, and you can export the result as XLSX if you want the numbers rather than an upload.
Can GOTOES move activities from Garmin Connect to Strava?
Yes, and selectively, which is the point of it. Garmin's own Strava connection syncs everything automatically once enabled. The GOTOES Garmin-to-Strava tool instead shows your Garmin activities and lets you send the ones you choose, so nothing you would rather not post ends up in your feed. It needs a GOTOES account with Garmin connected on your dashboard first, and a donation of $10 or more.
My race GPS is broken. Can this fix it?
Often, if you have a course file for the event. The Race Repair tool takes exactly two files, your recorded activity with whatever sensor data survived, and a course file for the route, and generates a position track fitted to your actual start and finish times. It then sends you to the merger to combine that track with your heart rate and cadence. The result is an activity that follows the real course rather than the line your watch drew through the buildings.
Is GOTOES still maintained?
Yes, and visibly. Every tool carries a version number and its own changelog, and the merger was updated to version 43.8 on September 29, 2026. Recent entries deal with specific, current problems: catching subtler GPS jumps, KML exports that open cleanly in Google Earth, and splitting multisport files by sport. Support runs through a forum on the site rather than a ticket system, and the changelog page doubles as the status page if the site ever goes down.
