How to Use FTP for Training Zones
Learn how to calculate and use cycling training zones from your FTP. Understand what each zone targets, how much time to spend there, and common zone systems.
Your FTP is only useful if you put it to work through training zones. Zones translate a single threshold number into a complete training system—from recovery rides to all-out efforts. Here's how to use them effectively.
What Are Training Zones?
Training zones divide the intensity spectrum into ranges that target specific physiological systems. Each zone produces different adaptations:
- Low zones build aerobic base
- Middle zones develop sustainable power
- High zones increase maximum capacity
By training in specific zones, you target specific adaptations rather than randomly riding "hard" or "easy."
Calculate Your Zones
Use our Power Zones Calculator to instantly generate your zones from FTP. Or calculate manually:
7-Zone System (Coggan)
| Zone | Name | % of FTP | Purpose |
|---|---|---|---|
| 1 | Active Recovery | < 55% | Recovery between hard days |
| 2 | Endurance | 56-75% | Aerobic base building |
| 3 | Tempo | 76-90% | Muscular endurance |
| 4 | Threshold | 91-105% | FTP improvement |
| 5 | VO2 Max | 106-120% | Aerobic capacity |
| 6 | Anaerobic | 121-150% | Short power |
| 7 | Neuromuscular | Max | Sprint power |
Example (FTP = 250W):
- Zone 1: < 138W
- Zone 2: 140-188W
- Zone 3: 190-225W
- Zone 4: 228-263W
- Zone 5: 265-300W
- Zone 6: 303-375W
- Zone 7: Max efforts
5-Zone Simplified System
| Zone | Name | % of FTP |
|---|---|---|
| 1 | Recovery | < 55% |
| 2 | Endurance | 55-75% |
| 3 | Tempo | 76-90% |
| 4 | Threshold | 91-105% |
| 5 | VO2 Max+ | > 105% |
Simpler to track, but less precise for structured training.
Zone-by-Zone Guide
Zone 1: Active Recovery (< 55% FTP)
What it feels like: Easy spinning. Could talk normally without effort. Barely feels like exercise.
Duration: 30-60 minutes typically.
When to use:
- Day after hard training
- Between interval sets (sometimes)
- Easy spin before travel or rest days
Adaptations: None directly—this zone promotes recovery, not fitness gains.
Common mistake: Going too hard. If you're above 60% FTP, you're not recovering—you're training.
Zone 2: Endurance (56-75% FTP)
What it feels like: Comfortable but requires focus. Can hold conversation in short sentences. Core of base training.
Duration: 60 min to 4+ hours.
When to use:
- Long rides
- Base building periods
- Recovery weeks (shorter duration)
- Between hard interval days
Adaptations:
- Increased capillary density
- Improved fat oxidation
- Aerobic enzyme development
- Mental endurance
Common mistake: Riding too hard. Zone 2 should feel almost too easy, especially early in rides.
Zone 3: Tempo (76-90% FTP)
What it feels like: "Comfortably hard." Conversation limited to phrases. You're working but not suffering.
Duration: 20-60 minutes in zone.
When to use:
- Muscular endurance development
- Gran fondo simulation
- Group ride pace
Adaptations:
- Improved lactate clearance
- Increased glycogen storage
- Mental toughness at sustained effort
Common mistake: Training here too often. Zone 3 is sometimes called "junk miles"—harder than Zone 2 but not as effective as Zone 4 for threshold development.
Zone 4: Threshold (91-105% FTP)
What it feels like: Hard. Breathing is labored. Limited to single words. You're questioning your life choices.
Duration: 10-40 minutes total.
When to use:
- Directly targeting FTP improvement
- Race simulation
- Time trial preparation
Adaptations:
- Increased FTP
- Improved lactate threshold
- Better pace judgment
- Mental strength
Common mistake: Not enough recovery. Zone 4 creates significant training stress and requires easy days before and after.
Zone 5: VO2 Max (106-120% FTP)
What it feels like: Very hard. Can only sustain for a few minutes. Breathing at maximum. Heart rate near max.
Duration: 2-8 minutes per interval, 15-30 minutes total.
When to use:
- Building aerobic ceiling
- Raising VO2 max
- Preparing for criteriums or punchy races
Adaptations:
- Increased VO2 max
- Better oxygen delivery
- Improved high-end power
- Cardiac development
Common mistake: Too much volume. VO2 max work is demanding—1-2 sessions per week maximum.
Zone 6: Anaerobic Capacity (121-150% FTP)
What it feels like: Maximum effort. Lasts 30 seconds to 3 minutes. Complete focus required.
Duration: 30 sec to 3 min per effort.
When to use:
- Sprint development
- Attack training
- Anaerobic power building
Adaptations:
- Increased anaerobic capacity
- Better power during surges
- Improved sprint finish
Zone 7: Neuromuscular (Max)
What it feels like: All-out sprint. 5-15 seconds maximum effort.
Duration: 5-15 seconds.
When to use:
- Sprint training
- Track racing prep
- Explosive power development
Adaptations:
- Maximum power output
- Neuromuscular recruitment
- Sprint technique
Time in Zone Guidelines
Not all zones deserve equal time. Here's a general distribution for most cyclists:
| Zone | Weekly Time Percentage |
|---|---|
| Zone 1-2 | 65-80% |
| Zone 3 | 5-15% |
| Zone 4 | 10-20% |
| Zone 5-7 | 5-10% |
This follows the polarized training principle—most time easy, some time very hard, minimal time in the middle.
By Training Phase
Base Phase:
- Zone 1-2: 80-85%
- Zone 3: 10-15%
- Zone 4+: 5%
Build Phase:
- Zone 1-2: 70-75%
- Zone 3-4: 20-25%
- Zone 5+: 5-10%
Peak Phase:
- Zone 1-2: 60-70%
- Zone 3-4: 15-20%
- Zone 5+: 10-15%
Common Zone Systems Compared
Coggan (7-Zone)
Most detailed and widely used. Preferred for structured power training.
5-Zone
Simpler, combines anaerobic zones. Good for beginners or heart-rate based training.
Sweet Spot
Not a traditional zone but the 88-94% FTP range used in sweet spot training. Bridges Zone 3 and Zone 4.
Polarized
Not zones per se, but a philosophy: very easy (Zone 1-2) or very hard (Zone 4+). Minimal time in Zone 3.
Using Zones in Practice
Workout Prescription
Training plans specify zones:
- "2x20 at Zone 4" = two 20-minute efforts at 91-105% FTP
- "60 min Zone 2" = one hour between 56-75% FTP
- "5x3 min Zone 5" = five 3-minute efforts at 106-120% FTP
Pacing Races
Zones help with race pacing:
- 20-minute time trial: Zone 4 (100-105% FTP)
- 2-hour road race: Zone 3-4 on climbs, Zone 2 on flats
- Gran fondo: Mostly Zone 2-3, saving Zone 4 for key moments
Recovery Assessment
Zones help gauge recovery:
- If Zone 2 feels like Zone 3, you need more rest
- If Zone 4 power is impossible, you're fatigued
- Use morning resting heart rate alongside zone perception
When to Update Zones
Your zones become inaccurate when:
- FTP improves (zones should get harder)
- FTP drops (zones are now too hard)
- You've been training 4-8 weeks consistently
Retest FTP every 4-8 weeks and update zones using our Power Zones Calculator.
Tracking Zone Distribution
Monitor your weekly zone distribution using training software. The TSS Calculator helps quantify overall load, but zone tracking shows intensity distribution.
Most athletes naturally gravitate toward Zone 3—hard enough to feel productive, easy enough to complete. Fight this tendency by keeping easy days truly easy and hard days truly hard.
Focus on Zone 2
Zone 2 training deserves special attention. It's where most of your training volume should occur, building the aerobic base that supports all other work. Use our dedicated Zone 2 Cycling Calculator to find your Zone 2 power range with different calculation methods.
