How often should I do high-intensity zone workouts?

Most cyclists benefit from 2-3 high-intensity sessions per week (Zone 4 and above), with at least 48 hours between hard efforts. The remaining training should be Zone 1-2 recovery and endurance work. More isn't always better - quality over quantity.

What zone should most of my training be in?

Research supports the 80/20 approach: 80% of training time in Zone 1-2 (easy), 20% in Zone 4+ (hard). Avoid spending too much time in Zone 3 (tempo), which provides less adaptation benefit while generating significant fatigue.

How long should Zone 5 intervals be?

Zone 5 (VO2max) intervals typically range from 2-5 minutes with equal or slightly longer recovery. Shorter intervals (2-3 min) can be repeated more times, while longer intervals (4-5 min) require fewer repetitions. Total time at VO2max should be 12-20 minutes per session.

Can I do power zone workouts on a trainer?

Yes, indoor trainers are ideal for power zone workouts because they provide consistent resistance and no traffic interruptions. Smart trainers with ERG mode can automatically adjust resistance to keep you in the target zone. Many cyclists find indoor training more effective for structured intervals.

Zone 1: Active Recovery (55-75% FTP)

Zone 1 promotes blood flow and recovery without adding training stress. Use these sessions after hard efforts or on scheduled recovery days.

Recovery Spin - 30-45 minutes

Entire ride at 55-65% FTP
Cadence: 85-95 RPM
Heart rate should stay low - if it drifts up, you're going too hard
Feel: Conversation is effortless, legs spinning freely

Zone 2: Endurance (75-90% FTP)

Zone 2 builds aerobic base, improves fat oxidation, and enhances mitochondrial density. This should comprise 60-70% of your total training volume.

Long Endurance Ride - 2-4 hours

Maintain 75-88% FTP throughout
Avoid surges on climbs - smooth power output
Cadence: 80-95 RPM
Feel: Comfortable conversation possible, sustainable for hours

Cafe Ride - 1.5-2 hours

Upper Zone 2: 85-90% FTP
Slightly more effort but still aerobic
Good for building toward longer rides

Zone 3: Tempo (90-105% FTP)

Tempo work develops muscular endurance. Use sparingly - it creates fatigue without the specific adaptations of true threshold or VO2max work.

Tempo Blocks - 60-90 minutes

2-3 x 15-20 min at 90-100% FTP
5 min easy spinning between blocks
Warm up: 15 min progressive
Feel: Breathing elevated but controlled, talking in short sentences

Zone 4: Threshold (100-120% FTP)

Threshold work increases FTP directly. These workouts should feel hard but sustainable - you're training at the edge of what you can maintain for extended periods.

Classic 2x20 - 75 minutes

Warm up: 15 min with 3 x 1 min builds
2 x 20 min at 95-100% FTP
5 min recovery between intervals
Cool down: 10 min easy
Feel: Hard but sustainable, talking in single words only

Threshold Progression - 90 minutes

3 x 15 min at 100-105% FTP
5 min recovery between
Each interval should feel progressively harder
If you can't complete all three, FTP may need adjustment

Zone 5: VO2max (106-120% FTP)

VO2max intervals push your aerobic ceiling higher. These are hard - you should be gasping by the end of each interval.

Classic VO2max Intervals - 60 minutes

Warm up: 15 min including 2 x 2 min builds
5-6 x 3 min at 110-120% FTP
3 min recovery between intervals
Cool down: 10 min easy
Feel: Breathing very hard, can only say a few words

Billat 30/30s - 45 minutes

2-3 sets of 10 x (30 sec on / 30 sec off)
On: 120-130% FTP
Off: 50% FTP soft pedaling
5 min between sets
Accumulates significant time at VO2max

Zone 6: Anaerobic Capacity (120-150% FTP)

These short, intense efforts develop your ability to produce power above threshold - critical for attacks, climbs, and race finishes.

Anaerobic Capacity Blocks - 50 minutes

Warm up: 15 min with opener sprints
8 x 1 min at 130-150% FTP
2 min recovery between
Cool down: 10 min easy
Feel: Extremely hard, burning legs, gasping

Zone 7: Neuromuscular Power (Max)

Sprint work develops raw power and neuromuscular coordination. Full recovery between efforts is essential.

Sprint Intervals - 45 minutes

Warm up: 20 min including leg openers
6-8 x 10-15 sec maximal sprints
5 min easy spinning between sprints
Start from low speed or rolling
Focus on explosive power, not sustaining

Weekly Workout Distribution

A well-structured training week might include:

Monday: Rest or Zone 1 recovery spin
Tuesday: Zone 4/5 intervals (threshold or VO2max)
Wednesday: Zone 2 endurance (1-2 hours)
Thursday: Zone 4 threshold work
Friday: Zone 1 recovery or rest
Saturday: Long Zone 2 ride (2-4 hours)
Sunday: Zone 2/3 group ride or endurance

Execution Tips

Nail the warmup: Skipping warmup reduces interval quality
Respect recovery: Easy intervals should be truly easy
Consistent cadence: Maintain target RPM throughout intervals
Quality over quantity: Better to cut a workout short than to complete it poorly
Cool down matters: Light spinning aids recovery for the next session
