How to Actually Use Endurance Test Results (Instead of Just Chasing Numbers)
Endurance test results are useful, but they're never the full story. Two athletes can have the same FTP or the same power at threshold and still respond very differently to the same training. See the guide on what's limiting your VO2 max for more on how to train based on your specific limiter.
Test results are only a starting point
The numbers give you a place to begin. They help you set initial paces and intensities. What actually happens when you apply those numbers depends on the individual. Recovery, daily stress, sleep, and how well you tolerate the work all play a role.
Don't treat the test number as something you have to hit exactly every session. Use it as a reference and then adjust based on how the work feels that day.
Progressions should come from real life
I like using test results to write progressions. For example, I might plan to add 5 or 10 watts per week on certain intervals. But the plan is always secondary to what actually happened last week.
If you can't hit the planned increase, we change the plan. If it felt too easy, we push harder. The test gives you a direction. Your actual performance week to week tells you the right speed to move in that direction.
Trends matter more than single numbers
One test by itself doesn't tell you much. The value comes from repeating the same test over time under similar conditions. You want to see whether the numbers are moving in the right direction and how quickly.
As long as you keep the test protocol consistent, the exact version of the test matters less than doing it the same way each time.
Key Takeaways
Test results give you a starting point for paces and progressions, not a rigid target you must hit every session.
Always adjust based on what happened in the previous week rather than following the plan blindly.
Consistent retesting shows trends. A single number is much less meaningful.

Frequently Asked Questions
What if I can't hit the watts the test suggested?
That's normal. Lower the target and keep training. The test gave you an estimate. Your body in the moment is the real data.
How long should I stick with one test protocol?
Use the same protocol for at least 8 to 12 weeks if you want to see clear trends. Changing the test every month makes it hard to compare results.
Should I share my test numbers with my coach?
Yes. The raw number is less important than the context around it. Tell your coach how the effort felt and what else was going on that week.
