Cycling power zones turn one FTP estimate into watt ranges that can be used in a training plan. The familiar seven-zone model runs from recovery riding below 55% of FTP to short neuromuscular work above 150%.
The percentages are a prescription framework, not seven laboratory measurements. They help a coach or rider answer, “What watt range does this workout mean?” They cannot independently answer, “Where are this rider's lactate and ventilatory thresholds?” or “How should every week be distributed?”
Use the FTP zone calculator when you want instant, gap-free watt ranges. Use this guide when you want the chart, the meaning of each range and the limits around the result. If you do not yet have an FTP input, begin with the FTP test calculator and keep the chosen protocol attached to the number.
Cycling power zone chart
Roadman uses the conventional Allen-Coggan-style boundaries published in the TrainingPeaks seven-level reference. Written without ambiguous shared endpoints, they are:
- Zone 1 — Active Recovery: up to 55% FTP
- Zone 2 — Endurance: above 55% through 75% FTP
- Zone 3 — Tempo: above 75% through 90% FTP
- Zone 4 — Threshold: above 90% through 105% FTP
- Zone 5 — VO2max: above 105% through 120% FTP
- Zone 6 — Anaerobic Capacity: above 120% through 150% FTP
- Zone 7 — Neuromuscular Power: above 150% FTP
Those names describe the typical purpose and feel of work in each band. Adaptations overlap. Crossing from 90% to 91% FTP does not switch one pathway off and another on.
Different platforms can use different names, ranges and rounding. When moving a workout between systems, compare the actual percentages or watts rather than assuming “Zone 2” means the same thing everywhere.
Worked FTP zone chart: 280 W
For a rider with a 280 W FTP, the Roadman calculator rounds each upper percentage boundary down to a whole watt, then begins the next zone one watt higher:
- Zone 1: 0–154 W
- Zone 2: 155–210 W
- Zone 3: 211–252 W
- Zone 4: 253–294 W
- Zone 5: 295–336 W
- Zone 6: 337–420 W
- Zone 7: 421 W and above
This rule prevents the common display problem where one table leaves a missing watt or assigns the same watt to two zones. The arithmetic is deterministic; the interpretation is still a starting point.
What each cycling power zone is for
Zone 1: active recovery — up to 55% FTP
Zone 1 is very light riding. It commonly appears in warm-ups, cool-downs, easy spins between intervals and deliberately low-load recovery sessions.
The label does not guarantee recovery. A long ride at low power still adds load, and an athlete who is ill, under-fuelled or carrying unusual fatigue may need rest rather than more riding. The session purpose matters more than earning a coloured bar in the training file.
Zone 2: endurance — above 55% to 75% FTP
Zone 2 is the conventional endurance range in this seven-zone system. It is commonly used for longer steady riding where accumulating controlled volume is the aim.
Fixed FTP percentages do not locate every rider's first lactate or ventilatory threshold. Use breathing, conversation, RPE and heart rate as cross-checks. If a supposedly steady endurance target repeatedly produces escalating strain under normal conditions, investigate the FTP input, heat, fuelling, fatigue and the individual's response instead of defending the percentage.
For a deeper comparison of anchors, see Zone 2 by power, heart rate and RPE.
Zone 3: tempo — above 75% to 90% FTP
Zone 3 is sustained tempo work. It may be used for event-specific steady pressure, long climbing blocks or controlled muscular-endurance sessions.
Calling the entire range “junk” or a “grey zone” is too blunt. The problem is usually unplanned drift: an easy ride becomes too demanding, while a quality session never reaches its intended target. When tempo is the planned purpose and the dose fits the programme, it is not a failed workout.
Zone 4: threshold — above 90% to 105% FTP
Zone 4 surrounds the FTP anchor. Common prescriptions include controlled sustained intervals near FTP, but the correct duration and recovery depend on the rider, the phase and the purpose.
FTP is not a promise that every rider can hold the number for exactly one hour. In a study of cyclists at different performance levels, time to exhaustion at an FTP20 estimate varied materially and rose with performance level (Sitko et al., 2022). Track FTP and time to exhaustion separately.
For workout construction, use the maintained threshold intervals guide.
Zone 5: VO2max — above 105% to 120% FTP
Zone 5 is commonly used for several-minute, high-intensity aerobic intervals. The FTP percentage supplies a starting range, not a guarantee that the same target and interval duration suit every rider.
Power-duration shape differs. A rider with strong short-duration power and another with strong durability can share the same FTP while responding differently above it. Use repeatable execution, RPE, breathing and time accumulated near the intended response to adjust the session. See cycling VO2max intervals for the specific progression.
Zone 6: anaerobic capacity — above 120% to 150% FTP
Zone 6 covers short, demanding efforts where anaerobic contribution is substantial. Examples include short climbs, attacks and race-specific repetitions.
FTP becomes a weaker individual anchor as duration shortens. Two riders with equal FTP can have very different one-minute and three-minute power. A power-duration profile is more informative than assuming a fixed FTP percentage describes the same capacity in everyone.
Zone 7: neuromuscular power — above 150% FTP
Zone 7 is the open-ended sprint range. Its lower boundary is expressed relative to FTP, but sprint prescription is usually better described by duration, intent, technique and maximal or near-maximal execution than by holding a narrow percentage.
For a rider preparing for long endurance events, this range may occupy little training time. For sprint- or race-specific goals it can matter more. The event decides the relevance; the chart does not.
Seven power zones versus three training zones
This is the most important interpretation boundary on the page.
The seven-zone model is commonly used to prescribe cycling workouts. Training-intensity-distribution research often groups work into three physiological domains around two thresholds. Those systems are not numbered the same way and cannot be mapped label-for-label.
That means “80% in Zone 2” is ambiguous. It might refer to:
- 80% of time in a seven-zone endurance band;
- 80% of sessions whose primary goal is below the first threshold;
- 80% of measured time in the lowest of a three-zone model; or
- a loose summary of a polarised programme rather than an audited calculation.
A 2025 individual-participant network meta-analysis found no statistically significant universal winner between polarised and other distributions for its primary outcomes, and reported that athlete level may alter the response (Rosenblat et al., 2025). The honest conclusion is not “intensity distribution does not matter.” It is that the athlete, phase, model and complete programme matter too much for one slogan to prescribe every week.
For that specific programming question, read polarised training for cycling and polarised versus sweet spot.
How accurate are FTP-based zones?
They are useful when the input and limitations are understood.
The FTP test must be repeatable
The 20-minute protocol can show good test-retest reliability in trained cyclists when the protocol is standardised (Borszcz et al., 2020). Reliability does not make every FTP method interchangeable.
Use the same power meter, calibration practice, test format, environment and preparation when tracking change. A small zone shift is not automatically fitness if the input came from a different protocol or conditions.
Critical power and FTP are related, not identical
Karsten and colleagues found strong correlation between critical power and an FTP20 estimate, but limits of agreement wide enough that the measures should not be substituted for individual decisions (Karsten et al., 2021).
If a plan is built from critical power, keep it in that model. If it is built from FTP, disclose the FTP method. Avoid silently replacing one anchor with another.
FTP does not equal every lactate landmark
FTP20 can relate strongly to several lactate landmarks while still differing from them. Research in road cyclists advises caution when using FTP as a substitute for laboratory lactate thresholds (Sitko et al., 2022).
The practical rule is simple: an FTP percentage is a field prescription. Do not present it as a laboratory measurement the rider never had.
How to use cycling power zones in a real week
Start with the session, not the colour:
- Name the purpose. Recovery, endurance, tempo, threshold-related work, VO2max-oriented work, anaerobic capacity and sprinting are different jobs.
- Choose the appropriate zone and duration. The same band can support different interval structures; the complete dose includes work time, recovery, repetitions and weekly context.
- Cross-check the rider. Use watts with RPE, breathing, heart rate, technique and repeatability.
- Count every demanding session. Races, hard group rides, strength work and other sports still contribute stress even when they are not labelled in the planned zone schedule.
- Review the response. A target that repeatedly misses the intended response may reflect stale FTP, inappropriate duration, fatigue, heat, fuelling or an individual power profile.
There is no universal number of hard sessions or mandatory zone percentage for every cyclist. If the week must account for age, work, recovery, race demands and progression, that is a coaching decision rather than a calculator output. The Roadman coaching framework is built around that distinction.
Which Roadman FTP page should you use?
These pages have separate jobs:
- Use the FTP zone calculator to turn a current FTP into seven gap-free whole-watt ranges.
- Use the FTP test calculator to estimate FTP from a completed protocol.
- Use What percentage of FTP is each zone? for the short percentage answer.
- Use FTP in cycling for the broad definition, test choices, limitations and routes to related topics.
- Use the masters FTP benchmark calculator for age- and sex-qualified benchmarking, not workout zones.
- Use this guide for the full zone chart, interpretation and evidence boundaries.
Keeping those jobs distinct helps a rider reach the right answer without forcing calculation, benchmarking and physiology into one page.

- Relationship Between the Critical Power Test and a 20-min Functional Threshold Power Test in Cycling — agreement limits between CP and FTP20;
- Functional Threshold Power as an Alternative to Lactate Thresholds in Road Cycling — caution around substituting FTP for lactate landmarks;
- Time to Exhaustion at Estimated Functional Threshold Power — rider-level variation in sustainable duration; and

Frequently asked questions
What are the seven cycling power zones?
This guide uses Zone 1 up to 55% FTP, Zone 2 above 55% to 75%, Zone 3 above 75% to 90%, Zone 4 above 90% to 105%, Zone 5 above 105% to 120%, Zone 6 above 120% to 150%, and Zone 7 above 150%.
How do I calculate FTP zones in watts?
Multiply FTP by each percentage boundary or use the FTP zone calculator. Roadman rounds each upper boundary down to a whole watt and starts the next range one watt higher, preventing gaps and overlaps.
What percentage of FTP is Zone 2?
Zone 2 is above 55% through 75% FTP in this seven-zone model. A three-zone research model can use the same label for a different physiological domain, so always state the system.
Is FTP the power I can hold for one hour?
Not reliably for every rider. FTP is a practical threshold-related marker, while observed time to exhaustion at an FTP20 estimate varies. Track the power value and sustainable duration separately.
How often should I update cycling power zones?
Retest after a meaningful training block or when repeated, comparable sessions show the current targets no longer fit their purpose. There is no universal six- or eight-week rule; keep the method and conditions consistent.
Should cyclists spend 80% of training in Zone 2?
Do not use that phrase without defining the zone system and counting method. Polarised research normally uses three domains rather than this seven-zone chart, and the evidence does not establish one universal distribution for every cyclist.
Calculate the current numbers with the FTP zone calculator. If the ranges still do not match the intended sessions, Ask Roadman can help identify whether the issue is the test, the workout design or the programme around it.
