Threshold Heart Rate Cycling – Essential Insights

What is threshold heart rate cycling?

Threshold heart rate cycling refers to the intensity at which your heart rate reaches a level that is sustainable for a significant duration yet high enough to provide substantial training benefits.

This intensity is often described as a balance between aerobic and anaerobic exercise, where you are pushing your body to adapt to higher levels of exertion without overextending into exhaustive efforts that cannot be maintained.

To determine your threshold heart rate, you must undergo a structured test, typically involving a sustained effort such as a time trial, where you can measure your average heart rate during the latter part of the test when you have reached a stable yet challenging pace.

Training at this intensity is beneficial for improving your cardiovascular fitness, increasing your lactate threshold, and enhancing your ability to sustain high-intensity efforts for longer periods.

Including threshold heart rate training in your cycling training plan is crucial for performance improvement.

It allows your body to become more efficient at clearing lactate, a byproduct of exercise, and teaches your muscles to work harder for longer.

This type of training is typically integrated into a well-rounded cycling program, with specific sessions dedicated to threshold work to ensure progression while allowing for adequate recovery.

How do you calculate threshold heart rate cycling?

To accurately establish your threshold heart rate for cycling, you must perform a test that pushes you to a sustained, hard effort.

We’ll cover two methods to calculate your threshold heart rate cycling.

Time Trial (60 minutes)

The most common method involves a time trial, typically 20 to 30 minutes long.

Start with a warm-up of at least 15  minutes.

Then, move to the time trial step, which should last 40 minutes.

During this trial, you should aim to maintain the highest pace you can sustain for the entirety of the effort.

It’s crucial to avoid starting too aggressively, as this can lead to premature fatigue and skew the results.

End this effort with a cool-down of 5 minutes of easy pedaling.

Once you have completed the time trial, calculate the average heart rate for the final 20 minutes of the test.

This average is a reliable indicator of your threshold heart rate.

Time Trial (30 minutes)

This approach is for those who prefer a less time-consuming method.

Start with a warm-up of 15 minutes.

Then, execute a time trial of 8 minutes. Add a rest of 4 minutes of easy pedaling in Zone 2 (avoid free-wheeling).

Repeat the time trial effort of 8 minutes.

With the average heart rate of the two efforts, you can estimate your threshold heart rate.

Remember that your threshold heart rate can change with fitness levels, so it is advisable to retest periodically.

This ensures your training intensities remain effective and appropriately challenging as you progress.

Adapting your training zones based on updated threshold heart rate values will help optimize your cycling performance and training outcomes.
