Where to Ride Your Workout: Platform Import Guide

Structured workouts created on CT Yeh can be used in Zwift, MyWhoosh, Hammerhead Karoo, ROUVY and on Garmin head units. This page covers the actual import steps, supported formats and limitations for each platform.

All steps were verified against each platform's official support documentation (August 2026). Platform features change — defer to official docs if steps differ.

Platform support overview

Zwift	ZWO	Drop file into Documents/Zwift/Workouts/<your-id>/, restart Zwift
MyWhoosh	ZWO	Upload via official Workout Builder web app → Export to MyWhoosh
Hammerhead Karoo	ZWO FIT	Upload on Dashboard; syncs when the unit goes online

ROUVY	ZWO	Upload custom workout in web portal
TrainingPeaks Virtual	ZWO ERG MRC	Drop into Documents/TPVirtual/workouts

Bryton / iGPSPORT / Magene	—	Re-enter manually in each brand's app workout editor

Zwift

Native

Drop the .zwo file into Zwift's workout folder — it syncs to every device on your account, including iPad and Apple TV.

Download the .zwo file from the workout builder.
Windows: open Documents\Zwift\Workouts\; macOS: ~/Documents/Zwift/Workouts/.
Enter the numbered folder (your Zwift ID; pick the one with the most files if there are several).
Copy the .zwo file in.
Restart Zwift → Training → Custom Workouts.

Mobile and Apple TV builds have no file system — copy the file using a computer first, Zwift syncs it to your other devices.

MyWhoosh

Web upload

MyWhoosh has no local workout folder — upload through the official Workout Builder.

Download the .zwo file.
Open workout.mywhoosh.com and sign in with your MyWhoosh account.
Upload the .zwo; it is parsed into an editable preview.
Press Export to MyWhoosh.
The workout appears in the MyWorkout folder in the app.

If MyWhoosh is running during export, restart the game to refresh the workout list.

Hammerhead Karoo 2 / 3

Smoothest

No subscription, no plugins — upload on the Dashboard and it syncs to the unit.

Download the .zwo or .fit file.
Sign in at dashboard.hammerhead.io and select Workouts.
Click Add Workout and drag the file into the dialog.
The workout syncs the next time your Karoo is online (opening the Companion App speeds this up).
On the Karoo: Apps → Workouts → select → Follow Workout → press play in the Ride screen.

Karoo accepts only ZWO and FIT. ZWO Ramp and MaxEffort blocks and zone-based power targets are unsupported — workouts generated here already avoid all of these. A smart trainer or power/HR sensor is required to track target intensity.

Garmin Edge / Forerunner / Fenix

USB required

Copy the FIT workout straight onto the unit over USB — no subscription or third-party service needed.

Download the .fit workout file.
Connect the Garmin device by USB; it mounts as a drive.
Copy the .fit file into Garmin/NewFiles/.
Eject and unplug — the device files it into your workout list automatically.
On the device: Training → Workouts → select and start.

Garmin Connect (web and app) cannot import workout FIT files — the most common misconception. Use the USB method above or a supported third-party sync service.

Bryton / iGPSPORT / Magene

Manual entry

These brands currently offer no free file-import path, but each app has a built-in workout editor you can re-enter the workout into.

Keep the workout builder open for reference (durations and %FTP targets).
Bryton: Bryton Active app → Training → create workout.
iGPSPORT: create the workout in the app's training section, then sync.
Magene: OnelapFit app → workout editor → sync.
Sync to the head unit and ride.

These brands can connect to TrainingPeaks, but the free TrainingPeaks tier cannot schedule future workouts — which is exactly what head units sync — so the "free TrainingPeaks relay" route does not actually work. Community tools that claim to push workouts require handing over your brand cloud password; we do not recommend them.

ROUVY / TrainingPeaks Virtual / FulGaz

ZWO supported

These indoor platforms also accept .zwo files.

ROUVY: upload the .zwo in the custom workouts area of the web portal.
TrainingPeaks Virtual: drop into Documents\TPVirtual\workouts (ZWO / ERG / MRC).
FulGaz: import in the custom workout section of the app or website.

TrainingPeaks Virtual requires a paid TrainingPeaks plan.

Three common misconceptions

"Upload the workout FIT to Garmin Connect and it syncs to the head unit"

Garmin Connect cannot import workout FIT files. Use USB into Garmin/NewFiles/, or a supported third-party sync.

"A free TrainingPeaks account can relay workouts to my head unit"

The free tier cannot plan future workouts, and future calendar entries are exactly what head units sync — so it cannot serve as a relay.

"MyWhoosh works like Zwift — just drop the file in a folder"

MyWhoosh has no local workout folder; upload through the official Workout Builder instead.
