Update FTP

By default, Riduck estimates the rider's FTP based on riding activity data. The estimated FTP can be viewed in the Dashboard - My Status section. However, normal FTP estimation may be challenging in the following cases:

• When only low-intensity training is sustained or when only low-intensity training data is synchronized with Riduck.

• When the riding style is predominantly endurance or touring.

• When there has been a long break from training or riding due to injury or other reasons.

In such cases, Riduck recommends the following tests as alternative methods for estimating FTP:

• Ramp test

• All-Out Effort (Check peak power)

While there are various other methods for measuring FTP, Riduck neither recommends nor provides related features for these methods due to complex considerations.

How to TEST

Ramp Test

The Ramp test involves gradually increasing power output until exhaustion, following a brief warm-up. This testing method requires a smart trainer that supports ERG mode. The Ramp test can be conducted through various platforms, but it is primarily performed using Zwift. For Riduck Slowtwitch subscribers, the Ramp test can also be conducted within the Riduck platform using the Slowtwitch workout feature.

Testing through Zwift

Please synchronize the test riding data through Zwift to Riduck via Strava following the instructions provided within Zwift.

If the synchronization between Zwift, Strava, and Riduck is already set up, there is no need for additional uploads or synchronization.

All-Out Effort

Pedal as hard as you can for 4~60 minutes to determine your peak power output.

This method is used to estimate FTP based on the achieved power.

While indoor testing is recommended, if you have a suitable course nearby, you can also perform the test outdoors.

Warm up your body before starting and then give it your all for a full serveral minutes of pedaling.

If conducting the test outdoors, it is recommended to choose a route that includes a continuous uphill segment without any flat or downhill sections. Testing on flat terrain can be very dangerous and may result in significant errors in the results.

Check Peak Power & Test

Red pin = Peak power based on FTP.

If the test results are accurately reflected in Riduck, depending on the test method, either the conducted Ramp Test will be displayed in the list below the Riduck Power Profile screen or the n-minute power will be shown as the FTP reference.

However, in the following cases, the conducted test may not be reflected:

1. If during the test process, an All-Effort (maximum effort) was not exerted, regardless of the test method.

2. If the FTP derived from the FTP test is lower than the FTP calculated from previous tests or recent riding activity data.

3. If there has been a decrease in capacity compared to previous tests.

4. If there were errors during the test process.
