Over the last few weeks, many pro racers and their coaches have been busy testing in the lab. This early-season testing is a mainstay at the top level of the sport. It helps coaches understand their athletes’ fitness profiles and to set training intensity targets and priorities.
But fitness testing isn’t just for pros. It can be helpful for cyclists of all abilities – and in this feature we will explore the home-based testing protocols that you can undertake for a fraction of the cost of lab testing.
As a coach, I often have athletes use home-based testing because it can be performed more regularly, and also provides important data on actual performance as opposed to physiological metrics such as VO2max, which don’t always predict real-world performance very accurately.
We’ll follow two hypothetical athletes through this article to explore how well the different testing protocols work for different individuals, assessing the pros and cons of the different methods. Both datasets are from real athletes, albeit with names for confidentiality.
Our first athlete, Jane, describes herself as a “diesel engine”. She is able to maintain high power in steadier events (4.4W/kg for over an hour), but struggles to respond to breakaways. Our second athlete, Sarah, is a more explosive rider and excels in races with many surges and attacks. She has a slightly lower one-hour power of 4.3W/kg. Both are preparing for punchy criterium-style races.
The 20-minute FTP test
This protocol (see box) is intended to estimate Functional Threshold Power (FTP), which is the maximum sustainable power over 40-60 minutes. This closely corresponds to the maximum lactate steady state (MLSS), which is a key marker of endurance cycling fitness often tested in the lab.
A key benefit of this protocol is its simplicity. It’s easy to estimate FTP and see how this has changed in response to training. Training intensity zones can also be calculated based on percentages of FTP, such Dr Andrew Coggan’s intensity zones (see box).
A limitation of this test is that it only assesses one aspect of your fitness profile. Looking at the data from Jane and Sarah, below, we can say for sure that Sarah seems to have a slightly higher FTP.
However, the testing doesn’t tell us anything about how these athletes perform over shorter efforts, or what their endurance abilities might be like over several hours. On the basis of the FTP test alone, we can’t confidently say, for either athlete, what they should focus on in training.
