Swim.com allows you to **automatically sync** your swim data from **Garmin Connect** or manually upload **.FIT files**. This guide will walk you through both methods.

## **Automatic Sync via Garmin Connect API**

By linking your Garmin Connect account to Swim.com, all future swims recorded on your **Garmin device** will automatically sync to Swim.com within **seconds to a few minutes** after uploading to Garmin Connect.

### **Steps to Set Up Automatic Sync:**

1.  Ensure you have an **active Garmin Connect account** and that your Garmin device is set up.
2.  Open the **Swim.com** app on your mobile device.
3.  Navigate to **Settings** (gear icon) in the top right corner.
4.  Select **Integrations**, then choose **Garmin**.
5.  Tap the **"Connect to Garmin"** button to be redirected to the **Garmin Connect authorization portal**.
6.  Enter your **Garmin Connect login credentials** and agree to the **data-sharing terms**.
7.  Confirm the connection.

### **What Data Will Sync?**

*   **New swims** recorded on your Garmin device will **automatically** sync to Swim.com.
*   **Sync timing**: Typically, swims will appear **within seconds to a few minutes** after uploading to Garmin Connect.
*   **Historical sync**: Garmin will transfer only **the last 30 days** of swim data upon connection.
    *   **Older swim data** (beyond 30 days) must be manually exported and uploaded (see below).
    *   It may take **up to 72 hours** for the last 30 days of data to appear on Swim.com.

### **Troubleshooting Sync Issues:**

*   Ensure your **Garmin Connect account is correctly linked** in **Swim.com → Settings → Integrations**.
*   Verify that your **swim data has successfully uploaded to Garmin Connect** before checking Swim.com.
*   If older swims are missing, you may need to **manually upload .FIT files**.

## **Manual Upload of .FIT Files**

If you need to upload older swim data or experience sync issues, you can manually transfer your Garmin swims using **.FIT files**.

### **Steps to Manually Upload a .FIT File to Swim.com:**

1.  **Export the swim from Garmin Connect**:
    *   Open **Garmin Connect** in a web browser and locate your swim activity.
    *   Select the swim and choose **Export as .FIT file**.
    *   Save the file to your **computer or phone**.
2.  **Upload to Swim.com**:
    *   Open a web browser and go to [Swim.com](https://www.swim.com).
    *   Log in to your **Swim.com account**.
    *   On the homepage, locate the **file upload section** (drag-and-drop area).
    *   Either **drag and drop** the .FIT file into the upload box or click to browse for the file.
    *   The upload will begin, and the swim will be processed and added to your Swim.com feed.

### **Important Notes on Manual Uploads:**

✔ **Only Garmin & Suunto .FIT files** are supported.  
✔ **Uploads must be done via the Swim.com website**—mobile app uploads are **not supported**.  
✔ If the file is **corrupt or unsupported**, the upload may fail. Try re-exporting from Garmin Connect.

### **Key Takeaways:**

✔ **Automatic Sync**: New swims sync automatically after Garmin Connect upload.  
✔ **Last 30 Days of Swims**: Only recent swim data (past 30 days) syncs automatically upon connection.  
✔ **Older Swims Require Manual Upload**: Use .FIT file upload for older swim data.  
✔ **Web Upload Only**: Manual .FIT uploads must be done on **Swim.com’s website**, not the mobile app.
