Is a Fitness of 100 Good?
Your fitness number is a 42-day average of your training load — not a grade out of 100. Here's what it really measures, and what's a good value for your level.

Crossing 100 feels like a milestone — but a fitness of 100 isn't a grade out of 100, and it doesn't mean you've "arrived." Your fitness number is simply a 42-day average of your training load. It rises when you train more than your recent average, and drifts down when you train less.
What the number actually measures
Fitness (also called CTL, or Chronic Training Load) is a rolling average of the training stress you've absorbed over roughly the last six weeks. It reflects how much work you've been doing — not how fast or strong you are. Two riders with the same fitness number can have very different FTPs.
That's why the only fair comparison is to your own past self. A fitness of 60 that's steadily climbing is a healthier sign than a fitness of 100 that's been falling for a month.
Is my number "good"?
As a rough guide, your fitness number tracks how many structured hours you ride each week:
These are ballparks, not targets. A higher number isn't automatically better — it just means more accumulated load, which also demands more recovery.
Why won't it keep climbing?
If your fitness flattens out even though you're training hard, that's usually fine. To raise the average you have to keep doing more than the average — which isn't sustainable forever. A flat fitness number alongside a rising FTP means you're getting stronger on the same load. That's progress, not a plateau.
What to do with it
Watch the trend, not the absolute value. Build it gradually in your base phase, hold it steady when life is busy, and let it dip on purpose when you taper for an event. Consistency over months beats chasing a round number.
