Why your FTP isn't going up even though you're training more
You're training more hours, riding more days, and the number stays the same. Here's why your FTP isn't going up and how to break out of the plateau.
Why your FTP isn't going up even though you're training more
It's one of the complaints I hear most: "Coach, I'm training more than ever and my FTP won't budge." The problem is almost never effort. It's structure.
What FTP really is
FTP (Functional Threshold Power) is an estimate of the maximum power you can sustain for around an hour in a quasi-steady state. It's not a magic number or a test you have to pass every month. It's an anchor for dosing the rest of your zones: tempo, threshold, VO2max.
When your FTP stalls, it doesn't mean you stopped improving. It means your threshold-specific adaptation isn't getting the stimulus or the recovery it needs.
The "more volume = more performance" mistake
Piling on hours without a plan is the most common trap for the committed cyclist. Riding 12, 14, 16 hours a week in the middle zone (that famous "gray zone" between endurance and tempo) builds fatigue without building threshold.
Your body adapts to what you ask of it with specificity. If you never push it to threshold with intent, there's no physiological reason for threshold to go up. You're going to end up more tired, with more volume logged on your Garmin, and the same FTP.
Lack of structure and polarization
A plan that raises FTP has a clear logic: most of the time in real endurance (easy, conversational Z2), a well-managed slice of high intensity (threshold and VO2max), and very little time in the middle zone that doesn't add anything.
If your weeks look like "I go out with the group, hang on as long as I can, do an interval when I remember," you don't have a plan: you have a habit. And habits without direction don't move FTP.
Lack of rest and overtraining
Adaptations don't happen on the bike. They happen when you rest. If you never back off the load, if you never put in a recovery week every 3 or 4 weeks, if you sleep 5 hours and train 15, you're not giving your body the window to consolidate the training.
An FTP that drops after a hard block isn't always a bad sign, but an FTP that's been flat for months with accumulated fatigue almost always is.
How to tell if the problem is stimulus or recovery
Ask yourself honestly:
- How many sessions in the last 4 weeks were specifically threshold or VO2max, with measured intervals, not just "hard" on the group ride?
- Do you put in at least one easy week every 3 or 4 weeks?
- Do you sleep at least 7 hours most nights?
- Do your legs feel heavy every day, even in Z2?
If structured intervals are missing, the problem is stimulus. If there's too much chronic fatigue, the problem is recovery. A lot of the time it's both at once, and that's why your FTP won't move.
How I can help
If you've been training seriously, with a power meter and a Garmin, and you feel like you're leaving performance on the table, the answer isn't adding more hours. It's adding direction. I can help you diagnose where you're losing adaptation with 1:1 coaching, or you can start with proven structure using the prebuilt training plans.
