After four weeks of progressively intense training, it’s time for something that might surprise you: a workout that feels easier but still delivers serious adaptations. Meet the Tempo Progression 2×20 – the workout that proves “hard” and “effective” aren’t always the same thing.
This is what smart training looks like when you’ve built a solid base. Two 20-minute efforts at tempo intensity (76-90% FTP) that challenge your muscular endurance without the recovery demands of threshold or VO2max work. It’s sneakily harder than it looks, and that’s exactly the point.
The Deceptively Powerful Middle Ground
Tempo training sits in what many riders consider no-man’s-land: too hard to be easy, too easy to feel like “real” training. That’s a mistake that costs cyclists significant fitness gains.
At 76-90% FTP, you’re working at what coaches call “sustainable discomfort” – the highest intensity where your aerobic system still provides the majority of your energy. You’re breathing hard enough that conversation becomes difficult, but not so hard that you’re counting seconds until it’s over.
Here’s what makes tempo uniquely valuable: it delivers aerobic adaptations similar to hours of Zone 2 riding, but in a fraction of the time. Those long weekend rides that take 3-4 hours to create meaningful training stress? Tempo work packages similar stimulus into 40 minutes of focused effort.
For time-crunched riders who want to build and maintain fitness without dedicating entire days to training, tempo is the most underrated tool in the training toolkit.
The Workout Breakdown
Total Time: 60 minutes
Intensity: 5/10
Training Stress Score (TSS): 56
Structure:
- 10 minutes Easy Warmup (45-70% FTP): Get the blood flowing
- 20 minutes Tempo (76-88% FTP): First sustained effort
- 10 minutes Recovery (45-55% FTP): Active recovery between intervals
- 20 minutes Tempo (76-88% FTP): Second sustained effort
- 10 minutes Cool Down (35-50% FTP): Proper recovery to finish
Forty minutes of quality tempo work wrapped in a complete, well-structured hour. This is what purposeful training looks like when you’re balancing stress and adaptation.
Why This Works When You’re Tired
Coming off four weeks of Zone 2 endurance, VO2max micro-intervals, Sweet Spot efforts, and lactate-clearing over-unders, your body has accumulated significant training stress. You’re stronger, but you’re also tired.
This is exactly when tempo training shines. It provides enough stimulus to maintain and even build fitness, but without the deep fatigue that comes from constantly working at or above threshold. Think of it as productive recovery – harder than easy spinning, but manageable enough that you can do it without digging a deeper hole.
Tempo work targets the same aerobic adaptations as those long endurance rides: increased mitochondrial density, improved fat oxidation, better oxygen utilization, enhanced capillarization. But because the intensity is higher, you accumulate more training stress in less time, making it perfect for maintaining base fitness when your schedule gets tight.
The magic is in what it doesn’t do: it doesn’t trash your neuromuscular system like VO2max work, it doesn’t require 48-hour recovery like threshold intervals, and it doesn’t demand the time commitment of proper Zone 2 volume. It’s the Goldilocks intensity – just right when you need training to fit your life.
Who This Is Perfect For
This workout is invaluable if you:
- Need a challenging but manageable session after several weeks of high-intensity training
- Want to build aerobic capacity without the recovery cost of harder efforts
- Have limited training time but still need meaningful stimulus
- Are transitioning between training blocks and need active progression
- Ride in groups where the pace sits in this tempo zone for extended periods
- Need to develop the ability to sustain moderately high power for long durations
- Want to improve your “cruising speed” – the pace you can hold comfortably for hours
This is strategic training for riders who understand that progress isn’t linear and sometimes the smartest move is to consolidate gains before pushing harder again.
What It Actually Feels Like
Tempo has a distinct feeling that’s worth understanding. In the first few minutes of each 20-minute interval, you’ll settle into what feels like a solid, sustainable rhythm. Not easy, but not desperate. Your breathing is elevated but controlled. Your legs have a gentle burn but nothing alarming.
Around minute 8-10, something shifts. That “sustainable” feeling starts requiring focus. The effort that felt manageable now demands attention. Your breathing deepens. The burn in your legs intensifies. You’re not in crisis, but you’re definitely working.
By minute 15, you understand why this is called “sustainable discomfort.” You could continue – your body isn’t screaming at you to stop – but you’re genuinely ready for this interval to end. The last 5 minutes require mental engagement to maintain power rather than letting it drift downward.
Then comes the 5-minute recovery, which feels like pure luxury after 20 minutes at tempo. Your second interval starts, and here’s the test: can you match the power you held in interval one? If you can, you’ve nailed the intensity. If interval two feels significantly harder despite the same power, you probably pushed slightly too hard on interval one.
The goal is two matching 20-minute blocks that feel hard but controlled throughout. Not easy, definitely not crushing, but purposefully challenging.
The Benefits You’ll Notice
After 3-4 weeks of consistent tempo work (1-2 sessions per week):
Your “all-day pace” climbs. The power you can sustain for hours increases noticeably. Weekend group rides that used to feel like a struggle become manageable, and you’ll have energy left for harder efforts when they matter.
Muscular endurance improves dramatically. Your legs learn to resist fatigue at sustained power outputs. Climbs that used to break down your pedal stroke in the final minutes become efforts you can complete with consistent form.
Fat oxidation becomes more efficient. Your body gets better at using fat as fuel at higher intensities, preserving glycogen for when you really need it. This translates to better endurance on long rides and events.
The gap between your comfort zone and threshold narrows. As your tempo power improves, what used to be “hard” starts feeling more like “moderate.” Your aerobic engine strengthens across the board, making everything feel easier relative to your capabilities.
Recovery between training weeks improves. Because tempo doesn’t create the deep neuromuscular fatigue of harder intensities, you can maintain fitness and even make gains while allowing your body to absorb previous training stress.
How to Execute It Properly
Start conservatively. The tempo zone is broad (76-90% FTP), giving you significant room to find the right intensity. For these 20-minute intervals, aim for 80-85% FTP rather than pushing toward 90%. Save the upper end of tempo for shorter intervals or when you’re feeling particularly strong.
Resist the urge to drift up. There’s a temptation, especially if you’re coming from harder training weeks, to push into Sweet Spot territory (88%+). Don’t. The value of tempo training comes from sustaining the effort for the full duration without accumulating excessive fatigue. Stay in the zone.
Keep cadence comfortable. Unlike low-cadence strength work, tempo efforts should be done at your naturally preferred cadence (typically 85-95 rpm for most riders). The goal is sustainable power, not grinding through the intervals.
The recovery between intervals matters. Five minutes is just enough to clear some metabolic buildup without losing your rhythm entirely. Spin easy but don’t coast. Stay engaged. When that second interval starts, you should feel ready to match interval one.
Use the full warm-up and cool-down. Fifteen minutes of warm-up might seem excessive for “only” 80-85% FTP, but proper preparation ensures you can execute both intervals with quality. The cool-down helps begin the recovery process and makes a real difference in how you feel the next day.
Watch for power creep. It’s easy to let power drift upward as you get into the rhythm of each interval. Check your power every few minutes and adjust if you’ve crept above your target. Consistency matters more than heroics.
No Power Meter? Here’s Your Guide
Heart rate works reasonably well for tempo efforts since the duration is long enough for HR to stabilize. Aim for 75-85% of your maximum heart rate. It will take 3-5 minutes to climb into the zone, then should remain relatively stable throughout each interval.
The talk test is particularly useful for tempo. You should be able to speak in short sentences, but conversation would be labored. If asked to explain your weekend plans, you could do it, but you’d prefer not to. That’s tempo.
RPE should sit around 6 out of 10 – distinctly harder than endurance riding but nowhere near the 8-9 of threshold efforts. It’s work, but it’s sustainable work that you could theoretically maintain for much longer than 20 minutes if you had to.
The key marker: if you finish each 20-minute interval thinking “I could have done another 10-20 minutes at that pace,” you’ve nailed the intensity. If you finish thinking “thank god that’s over,” you pushed too hard.
Variations and Progressions
Shorter version: If 2×20 minutes feels too long, start with 2×15 or even 2×12 minutes. You’ll still get training benefit from the shorter duration while building toward the full workout.
Longer version: Progress to 2×25 or 2×30 minutes as your fitness improves. Eventually, you can work toward single 60-minute tempo efforts, which provide exceptional aerobic stimulus for time-crunched training.
Higher intensity progression: Once 2×20 at 80-85% FTP feels manageable, progress to 85-88% FTP. This bridges toward Sweet Spot training while maintaining the longer interval structure.
More intervals: Some riders respond better to 3×15 or 4×12 instead of 2×20. The total tempo time remains similar, but the psychological break of shorter intervals can make the workout feel more manageable.
Outdoor variations: Tempo work is excellent for outdoor training. Find a steady grade or long stretch of road where you can maintain consistent power. The mental engagement of outdoor riding often makes tempo feel easier than the same effort indoors.
The Reality About “Easy” Weeks
Let’s be clear: this isn’t an easy workout. It’s an easier workout relative to the high-intensity training you’ve been doing, but 40 minutes at tempo is real work that produces real adaptations.
What makes it “recovery-ish” is the absence of neuromuscular fatigue and the lower recovery demands. You can do this workout and be ready to train quality again within 24 hours. Compare that to a VO2max session or over-unders, which might require 36-48 hours before you’re ready for another hard effort.
This is strategic periodization in action. You’re not backing off because you’re weak – you’re moderating intensity to allow your body to absorb the previous training stress while maintaining forward momentum. Smart athletes understand that progress happens during recovery, not just during hard training.
Think of tempo weeks as consolidation phases. You’re cementing the gains from harder training while setting yourself up for the next progression. This is how you get faster over months and years rather than just weeks.

Free download, personalized zones, compatible with your preferred training platform. The usual VeloVostra approach – no barriers, just training.
Tempo work translates exceptionally well to outdoor riding. If you have a steady climb or quiet road, take this workout outside. The mental stimulation of real-world riding often makes tempo efforts more enjoyable than identical work on the trainer. Just ensure you have a route where you can maintain consistent power without frequent interruptions.
When to schedule this workout: Tempo fits beautifully mid-week when you need training stimulus but don’t have time for long endurance rides or the recovery window for harder intervals. It’s also excellent as a bridge workout when transitioning between training blocks or preparing for a week of higher intensity.
Your goal: complete both 20-minute intervals at 80-85% FTP with minimal power variation. If your power file shows steady, controlled effort throughout both intervals, you’ve executed perfectly. If interval two falls apart, start more conservatively next time.
