COL% — Ciclo Output Level — connects how demanding a class is with the rider riding it, so one shared class is a fair challenge for everyone in the room. It's what lets riders of very different strength ride the same class and compete fairly on one leaderboard.
What COL% looks at
COL% combines the things that actually make an effort hard — not the power zone alone:
Intensity — how hard the effort is.
Cadence — the RPM you're riding at.
Duration — how long the interval lasts.
Posture — seated or standing.
You — your own capacity, so the same effort is read correctly for each rider.
One profile, two uses
Class COL% — how demanding is the class? Rated from the whole session: zones, cadence, interval length, seated or standing, recovery and class length.
Your COL% — what does your ride mean? Your output, read interval by interval against the task and your own capacity — not raw watts.
How classes are graded
Classes are graded across roughly a 60–90% range, in four bands:
60–65% | Aerobic conditioning — lower overall demand, more controlled work and recovery. |
65–75% | Endurance — more sustained work and accumulated load, with manageable recovery. |
75–85% | Threshold — a more demanding profile, with sustained or repeated hard work. |
85–90% | High intensity — the highest overall demand, with carefully designed work and recovery. |
It's not a % of your FTP. An 80% class doesn't mean riding at 80% FTP — the grade describes the demand of the whole session, recovery included. The five interval zone colours (white, blue, green, yellow, red) still tell you what to do right now; the class grade sits above them and describes the session overall. So an endurance class can still contain hard yellow or red efforts and keep its endurance grade.
Fair on one leaderboard
Everyone in the class shares the same music, timing, cadence cues and zone colours — but each rider is scored against their own capacity. That's what keeps the leaderboard fair regardless of size, gender or ability.
For example, in the same interval one rider puts out 207 W and another 138 W. If both hit their own personal target, both rode that interval equally well — more watts doesn't automatically win.
Riding to your own level, you'll usually finish above an easier (low-COL%) class and below a tougher (high-COL%) one — that's expected, not a bad ride.
On the leaderboard and your dials
During class, the COL graph on your Rider Dials and the vs Class column on the leaderboard show your live output relative to the class COL% — above (+%), level, or below (−%). The leaderboard can also be ranked by COL%, Calories or W/kg.
