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)

ZoneName% of FTPPurpose
1Active Recovery< 55%Recovery between hard days
2Endurance56-75%Aerobic base building
3Tempo76-90%Muscular endurance
4Threshold91-105%FTP improvement
5VO2 Max106-120%Aerobic capacity
6Anaerobic121-150%Short power
7NeuromuscularMaxSprint 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

ZoneName% of FTP
1Recovery< 55%
2Endurance55-75%
3Tempo76-90%
4Threshold91-105%
5VO2 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:

ZoneWeekly Time Percentage
Zone 1-265-80%
Zone 35-15%
Zone 410-20%
Zone 5-75-10%

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.
