Some indoor cycling workouts are designed to build endurance. Others focus on threshold power or short, explosive efforts. But what happens when you combine all three into one session?
You get Spicy but Sensible — a progressive indoor cycling workout that starts with controlled aerobic efforts, moves into demanding Level V intervals, and finishes with short, sharp 20-second bursts.
It’s spicy enough to challenge your legs and cardiovascular system, but sensible enough to keep the hard work structured and purposeful.
Whether you’re a road cyclist, triathlete or someone looking to make the most of your time on the smart trainer, this session offers a combination of sustained efforts and high-intensity work.
And the best part? The entire cycling session takes just 40 minutes.
Today’s Goal: Develop Cycling Power Without Losing Control
The objective of Spicy but Sensible is to challenge several aspects of your cycling fitness within one carefully structured session.
You’ll begin with longer efforts around Levels III–IV before progressing to Level V intervals and finishing with eight short, high-intensity bursts at Level V+++.
The session targets:
- Aerobic endurance and muscular stamina: Through the initial sustained Level III–IV efforts.
- Aerobic power: Through four one-minute Level V intervals.
- High-intensity repeatability: Through eight 20-second Level V+++ efforts.
- Pacing and recovery discipline: By maintaining the prescribed intensities and respecting the easier recovery intervals.
The key is to avoid turning the first few efforts into an all-out race. You’ll need enough energy left to complete the final set with good technique and consistent power.
Why You’re Doing This Session
One of the biggest mistakes cyclists make with high-intensity training is treating every hard interval as an opportunity to produce their highest possible power.
That approach can work against the purpose of a structured session.
Spicy but Sensible takes a different approach.
The workout progressively changes the demands placed on your body, allowing you to experience several training intensities without spending too long at any one of them.
1. Controlled Level III–IV Efforts
The first two efforts last four minutes and three minutes respectively.
These longer intervals encourage you to settle into a strong, sustainable rhythm, maintaining consistent power without surging unnecessarily.
They’re an opportunity to practise controlled pacing before the shorter, harder efforts begin.
2. One-Minute Level V Intervals
Next come four one-minute Level V efforts, each separated by one minute of Level I recovery.
These efforts are designed to challenge your aerobic power.
You’ll need to increase your power output significantly compared with the earlier intervals, but the objective is still to maintain good technique and complete all four repetitions consistently.
3. Twenty-Second Level V+++ Bursts
Finally, you’ll complete eight repetitions of 20 seconds at Level V+++, followed by 40 seconds at Level I.
These are the spiciest efforts of the workout.
The shorter duration allows you to reach a higher intensity than the longer intervals, while the 40-second recoveries give you an opportunity to prepare for the next burst.
The challenge is maintaining quality across all eight repetitions rather than producing one exceptional effort followed by seven increasingly weaker ones.
Today’s Workout: Spicy but Sensible
Warm-Up — 10 Minutes
| Duration | Intensity |
|---|---|
| 5 minutes | Level I |
| 1 minute | Level I+ |
| 1 minute | Level II− |
| 1 minute | Level II+ |
| 1 minute | Level III− |
| 1 minute | Level III+ |
Gradually increase your intensity throughout the warm-up.
The progression should prepare your cardiovascular system and muscles for the harder work ahead without creating unnecessary fatigue.
Main Set — 25 Minutes
Part One: Sustained Efforts
| Duration | Intensity |
|---|---|
| 4 minutes | Level III–IV |
| 1 minute | Level II recovery |
| 3 minutes | Level III–IV |
| 1 minute | Level II recovery |
Start with a controlled effort and aim to maintain steady power throughout each interval.
Part Two: Aerobic Power
4x:
- 1 minute Level V
- 1 minute Level I recovery
These efforts should feel challenging but repeatable. Avoid starting the first interval so aggressively that you struggle to maintain the prescribed intensity during the remaining repetitions.
Part Three: Short, Sharp Efforts
8x:
- 20 seconds Level V+++
- 40 seconds Level I recovery
These are short, high-intensity bursts. Focus on producing strong, controlled power while maintaining good pedalling technique.
Cool-Down — 10 Minutes
– 10 minutes Level II
Allow your breathing and heart rate to settle as you finish the cycling session.
Post-Workout
– 10 minutes stretching
Three Coaching Tips for Spicy but Sensible
1. Don’t Overcook the Opening Efforts
The first four-minute and three-minute intervals should feel controlled.
You’ll be working around Levels III–IV, but remember that the most demanding part of the session is still ahead.
Finishing these efforts feeling strong is far more useful than exhausting yourself before the Level V intervals begin.
2. Make Your Recovery Intervals Count
Recovery intervals are part of the workout, not wasted time.
During the Level II and Level I recoveries, reduce your power as prescribed and allow your breathing to settle.
Trying to maintain a higher intensity during these periods may compromise your ability to complete the later intervals effectively.
3. Keep the Final Eight Efforts Consistent
The 20-second Level V+++ intervals are designed to be hard, but consistency matters.
Aim to produce a similar quality of effort across all eight repetitions.
If your power drops dramatically after the first few efforts, you may have started too aggressively.
Who Is This Workout For?
Spicy but Sensible is particularly suitable for cyclists and triathletes who already have experience with structured interval training.
It may appeal to:
- Road cyclists wanting to combine sustained power and short, hard efforts.
- Triathletes looking to develop cycling power alongside their endurance training.
- Indoor cycling enthusiasts who enjoy varied sessions.
- Time-conscious athletes who want a challenging workout without a lengthy ride.
Because the session includes Level V and Level V+++ efforts, it may be less appropriate for someone returning from a prolonged training break or beginning structured cycling training for the first time.
The intensity should always be appropriate for your current fitness and training experience.

Coach Ray’s Workout Data
One of the benefits of reviewing your completed workout is being able to compare your planned power with what you actually achieved.
For this session, I’d be particularly interested in how consistently you completed the four one-minute Level V intervals and whether you maintained your power during the final eight 20-second efforts.
Rather than focusing solely on your highest power output, look at how well you executed the entire session.

Frequently Asked Questions
Is Spicy but Sensible a VO₂ max workout?
It includes four one-minute Level V intervals that target aerobic power, alongside longer Level III–IV efforts and shorter Level V+++ bursts. It’s better described as a mixed-intensity session than a dedicated VO₂ max workout.
Should I ride the 20-second intervals as hard as possible?
Aim for the prescribed Level V+++ intensity rather than treating every repetition as an uncontrolled maximum sprint. The goal is to maintain strong, repeatable efforts with good technique.
Can I complete this workout outdoors?
Yes, provided you have a suitable stretch of road where you can safely complete the intervals without frequent interruptions. However, the short 20-second efforts and 40-second recoveries can be easier to execute consistently on an indoor trainer.
How often should I include a workout like this?
That depends on your training phase, overall workload and recovery. Because the workout contains several high-intensity efforts, it should be balanced with appropriate easier training rather than added indiscriminately to an already demanding week.
Coach Ray’s Final Thoughts
Spicy but Sensible is a reminder that effective cycling training doesn’t have to focus on just one intensity.
By progressing from controlled sustained efforts into Level V intervals and finally short, high-intensity bursts, this workout challenges several aspects of your cycling fitness within a single session.
But the real value comes from executing each part as intended.
Don’t turn the opening intervals into a race. Keep the recovery periods easy. And save enough energy to finish the final eight efforts with strong, consistent technique.
The workout should be spicy, but your pacing should remain sensible.
Happy training!
