Building fitness to power performance

At Lauf Gravel Worlds a couple weeks ago, both Coach Namrita Brooke and I lined up with a season of less than ideal preparation. Between interruptions, lower training volume, and the usual curveballs of summer, neither of us had the type of perfect lead-in we wanted for a major event. Yet we both rode strong and performed well. Why? Because we were able to lean heavily on the deep foundation of fitness we built last winter. That base carried us through, even when our peak training was less consistent. This is exactly why I believe so strongly in prioritizing solid and consistent winter training focused on building fitness to the highest level your schedule can accommodate.

Classic periodization framework

Classic periodization is the most time tested and widely used model for structuring an athlete's training year. It organizes training into distinct periods with clear objectives to ensure that each phase builds on the last. The goal is progressive development, moving from general fitness to specific performance readiness. By focusing first on building a strong aerobic and strength foundation, then layering in intensity and race specificity, athletes arrive at their key events with the right balance of fitness and freshness.

The traditional model of annual training is broken into four distinct periods:

• Base Period: This period is dedicated to developing aerobic capacity, strength, and durability.

• Build Period: This period focuses on raising intensity and moving training toward race-specific demands.

• Peak Period: This period is about refining fitness through race-like work while freshening the system.

• Race Period: This is when the training load decreases and performance is maximized.

BaseCamp periodization framework

My approach to periodization simplifies the language while keeping the structure intact. I refer to the Base and Build Periods collectively as the Fitness Period, because the focus is on building broad, sustainable fitness through aerobic development, strength, and progressive training load. A key focus here is simply building the highest Chronic Training Load (CTL) possible with a focus on aerobic capacity development following the BaseCamp model of consistency, rhythm and progression.

Once this foundation is in place, the focus shifts to what I call the Perform Period, which includes the traditional Peak and Race Periods. This is where training becomes highly specific to racing demands, emphasizing intensity (or extended duration), sharpening, and speed so athletes can fully express the fitness they have built. During this phase, we expect and plan a decline in CTL as we spend a little of our fitness in a tradeoff for high-quality specificity work, which typically means intensity.

By reframing periodization this way, I keep the emphasis on developing the deepest possible base first, then turning that fitness into performance when it matters most. This is how to use fitness as the anchor to the season.

Fitness as the anchor

In TrainingPeaks' Performance Manager Chart, Chronic Training Load (CTL) represents fitness. During the Fitness Period, the goal is to steadily and sustainably raise CTL to the highest level of the year. That peak of fitness then becomes the anchor for the entire season.

This distinction is critical. When CTL is high at the end of the Fitness Period, athletes can move into the Perform Period with confidence, focusing on race-specific intervals, sharpening, and speed rather than scrambling to increase training load. The Perform Period then becomes about freshness, tapering, and execution, allowing athletes to fully express the fitness they already built rather than trying to dig deeper into the well.

Fitness durability for dealing with challenges in season

A major advantage of committing to a large Fitness Period is the durability it gives us for the rest of the season. High aerobic fitness is like a reservoir; once it is built, it does not disappear quickly. Even if the summer brings interruptions, travel, illness, or inconsistent training, that strong foundation continues to support performance. With a well-developed aerobic base, we can maintain fitness with relatively modest training loads, which allows us to stay competitive and resilient all summer long. This is why I stress building the highest possible fitness early; it creates a safety net that keeps us strong even when life gets in the way.

I encourage athletes to fully commit to a large winter training season. Winter is the best time to steadily and progressively build aerobic capacity without the distraction of racing or events. Our highest Chronic Training Load of the year should come from this phase, not from the middle of summer. By stacking fitness in the winter, we build a large buffer to deal with summer inconsistency and training challenges of event season.

The pitfall of chasing fitness in the summer

Too many athletes make the mistake of trying to push CTL higher in the middle of the Perform Period. The risks are twofold.

• Fatigue and poor racing: The athlete is both racing and building a training load, leaving them too tired to perform

• Injury and burnout: Stress accumulates at the exact time the system needs balance and recovery.

Instead of arriving sharp and ready, these athletes often plateau or fade mid season.

A better way forward

Think of it this way: the Fitness Period is where we bank our fitness. That fitness should be at its highest before we step fully into the Perform Period. Once the season begins, our focus should shift from building fitness to expressing the fitness we already have.

This means committing early to steady aerobic development, progressive load, and strength work. This frees us to focus fully on race-specific work when it matters most.

Conclusion

A strong and well-executed Fitness Period does more than just build fitness; it also creates a buffer that protects us during the inevitable challenges of the event season. Racing schedules, travel, fatigue, and unexpected life interruptions can make training inconsistent, but when we start the year with a large foundation of aerobic fitness, we have reserves to draw from. That base allows us to stay strong, maintain performance, and keep competing even when things are less than perfect.

This is exactly what carried both Namrita and me through Gravel Worlds. Even with a summer of interruptions and lower training, the depth of our winter work gave us the strength to perform when it mattered most, thanks to our commitment to completing the winter BaseCamp training.
