Periodisation is how you turn 52 weeks of riding into structured progress rather than a random collection of efforts. The principle is straightforward: divide the year into phases — base, build, peak, race, and transition — where each phase prepares the foundation the next one builds on. Get the order and timing right and you improve steadily; skip a phase or scramble the sequence and you plateau by mid-season, wondering why your FTP hasn't moved since March.
Here's the thing nobody tells you about periodisation: the framework itself isn't complicated. Joe Friel published the annual training plan model decades ago and it still works. What's changed is how coaches like Dan Lorang and Dylan Johnson apply it — shorter mesocycles, more flexibility, reverse periodisation for certain athletes. We've had all three on the Roadman Podcast, and the conversations get specific about how to structure a season when you're not a full-time pro with a team dictating your calendar.

What Periodisation Actually Means
Periodisation is the systematic variation of training stress over time. That's it. You don't train the same way in November as you do in June, because the demands are different and the body adapts in layers.
The concept works at three levels:
| Level | Timeframe | What It Controls |
|---|---|---|
| Macrocycle | Full season (6-12 months) | Overall progression from base through peak |
| Mesocycle | 3-6 weeks | Specific training block with a single focus |
| Microcycle | 1 week | Day-to-day session structure within a block |
Most amateur cyclists accidentally periodise at the microcycle level only — they plan each week — but never zoom out to the mesocycle or macrocycle. That's how you end up doing the same 2x20 threshold session in January and July with no progression between them.

The Phases of a Periodised Year
Let me break this down. Every periodised season follows the same sequence, even if the durations change based on your event calendar:
| Phase | Typical Length | Primary Focus |
|---|---|---|
| Transition | 2-4 weeks | Off-bike or unstructured riding, mental reset |
| Base 1 | 4-6 weeks | Aerobic volume, Zone 2, building the engine |
| Base 2 | 4-6 weeks | Continued volume plus sweet spot introduction |
| Build 1 | 3-4 weeks | Threshold intervals, sustained power |
| Build 2 | 3-4 weeks | VO2max and race-specific intensity |
| Peak | 1-2 weeks | Reduced volume, sharpening sessions |
| Race | 1-8 weeks | Competition period, maintenance training |
The base phase is where most amateurs cut corners and it costs them later. Without 8-12 weeks of genuine aerobic work, the intensity phases have nothing to build on. Joe Friel has been saying this for 30 years and the data keeps proving him right: your aerobic ceiling determines how high your threshold can climb.
The build phase is where it gets interesting. Dan Lorang programs build blocks differently depending on the athlete — some respond to concentrated threshold work, others to mixed blocks with VO2max and tempo in the same week. The point is that build follows base, never the other way around.

Mesocycles: The Building Blocks
A mesocycle is a training block of 3-6 weeks with a single physiological focus and a recovery week at the end. It's the unit that actually drives adaptation.
The standard structure inside a mesocycle:
- Weeks 1-3: Progressive overload — increase volume, intensity, or both by 5-10% per week.
- Week 4: Recovery week — drop volume by 30-50%, keep 1-2 short intensity sessions to maintain sharpness.
That 3:1 ratio (three loading weeks, one recovery) is the default. Some athletes — particularly those over 40 or with high life stress — do better on 2:1 (two loading, one recovery). Dylan Johnson has talked about using a 2:1 structure during his own competitive seasons precisely because recovery capacity is finite.
Each mesocycle should have a clear objective: build aerobic base, raise threshold, sharpen VO2max, or taper for an event. Mixing all of them into one block is the training equivalent of trying to boil the ocean.

Traditional vs Reverse Periodisation
Traditional periodisation starts with high volume and low intensity in winter, then progressively adds intensity while volume drops toward summer events. It's the Friel model and it works extremely well for road cyclists targeting a mid-season peak.
Reverse periodisation flips the order: start with higher intensity and lower volume, then add volume as fitness and weather allow. It suits riders who:
- Have limited winter riding time (indoor-only, 6-8 hours per week)
- Target late-season or autumn events
- Struggle with motivation during long winter base blocks
- Are time-crunched year-round and need intensity to maintain fitness
Here's the contrast:
| Factor | Traditional | Reverse |
|---|---|---|
| Winter focus | High volume, low intensity | Low volume, high intensity |
| Summer focus | High intensity, reduced volume | Increasing volume |
| Best for | Spring/summer A-events | Autumn events, time-crunched riders |
| Risk | Boredom in base, lost fitness if base too long | Burnout if intensity too early, missing aerobic depth |
Neither is universally better. The right choice depends on your calendar, your available hours, and your physiology. Dan Lorang uses elements of both in his World Tour programming — base periods aren't entirely devoid of intensity, and build periods still contain aerobic work.

Building Your Annual Plan
Start with the calendar, work backwards.
Step 1: Identify your A-events. One or two races or sportives that matter most. Everything else is training or B-priority.
Step 2: Count backwards from each A-event. You need 1-2 weeks of peak, 6-8 weeks of build, and 8-12 weeks of base before that. Add a 2-4 week transition at the start of your training year.
Step 3: Place recovery weeks every 3-4 weeks throughout.
Step 4: Fill in the specifics. Each mesocycle gets a focus, each week gets a structure, each day gets a session type.
For a rider targeting a June sportive, a practical annual plan looks like this:
| Month | Phase | Focus |
|---|---|---|
| November | Transition | Off-bike, gym, cross-training |
| December-January | Base 1-2 | Zone 2 volume, sweet spot introduction |
| February-March | Build 1-2 | Threshold and VO2max blocks |
| April-May | Build 3 / Pre-peak | Race-specific work, pacing rehearsal |
| June | Peak + Event | Taper, race, recover |
The plan is the starting point, not a prison sentence. Life happens — illness, work travel, family demands. The best periodised plan is the one you adjust without abandoning.

Frequently Asked Questions
What is periodisation in cycling? Periodisation is the planned variation of training stress across your season. Instead of doing the same training year-round, you divide the year into phases — base, build, peak, race, and transition — each with a different physiological focus. The phases stack so that each one builds on the adaptations created by the one before it.
How long should a training block (mesocycle) be? Most mesocycles run 3-6 weeks, with the most common structure being three weeks of progressive loading followed by one recovery week. Athletes over 40 or those managing high life stress often do better with a 2:1 ratio — two loading weeks and one recovery week. The key is that each block has a single clear focus.
What is reverse periodisation, and should I use it? Reverse periodisation starts with higher intensity and lower volume, then adds volume later — the opposite of the traditional base-first approach. It works well for time-crunched riders, indoor-only winter training, and athletes targeting late-season events. If you have the time and discipline for a proper winter base block, traditional periodisation remains the stronger default.
Do I need an off-season? Yes. The transition phase — 2-4 weeks of unstructured activity, reduced volume, and mental reset — is where the accumulated fatigue of the season clears. Riders who train 12 months without a break consistently underperform in their second half of the following season. The off-season doesn't mean doing nothing; it means stepping away from structured training.
Can I periodise on limited hours? Absolutely. Periodisation is about the structure of training, not the volume. A rider on 6 hours per week still benefits from a base phase (more Zone 2, less intensity), a build phase (adding intervals), and a taper before events. The phases may be shorter — 3-4 week mesocycles instead of 6 — but the principle holds.
How do I know when to move from one phase to the next? Objective markers work best. For base-to-build: aerobic decoupling under 5% on a 2-hour ride signals your aerobic base is solid. For build-to-peak: when your key interval sessions are hitting target numbers consistently, it's time to reduce volume and sharpen. If sessions are declining in quality, extend the current phase or insert a recovery week before progressing.
