Why Vekta

Why Vekta

A Unified Performance System for Endurance Sport

Vekta is a training and coaching platform for endurance athletes and coaches. It integrates Critical Power modelling, load analysis, durability insights, and structured planning into one unified performance modelling system that connects physiology directly to daily training decisions.

Beyond FTP

For decades, endurance training has relied on simplified anchors such as FTP and composite stress scores. These tools represented meaningful progress. But they reduce performance to a single threshold and a blended score.

FTP is a fixed estimate of sustainable power. It does not distinguish between what you can sustain and the finite capacity you have above that level. It also does not describe how those capacities change as fatigue accumulates.

Modern endurance science shows that performance is not one number. It is the interaction between:

  • Sustainable capacity

  • High-intensity work capacity

  • Training stimulus

  • Recovery

  • Fatigue resistance

The Critical Power framework models this more precisely. It defines the boundary between sustainable and non-sustainable work, and W′ represents the limited work you can perform above that boundary [1–3].

This matters in practice.

It changes how intervals are prescribed. It changes how repeatability is interpreted. It changes how fatigue is understood in long events.

Impulse-response models show that performance evolves from the balance between stress and recovery over time [4]. Research into durability shows that output late in a session or race can diverge significantly from fresh capacity [5–6].

Performance is dynamic, not static.

Vekta builds these principles directly into its modelling and load interpretation. Capacity is not reduced to one number. Stress is not reduced to one blended score. Training decisions stay aligned with physiology.

When interpretation drifts from physiology, training decisions drift with it.

A Connected Performance Modelling System, Not Disconnected Tools

Most endurance software evolved from either calendar-based planning tools or standalone analytics environments.

In many cases, planning, modelling, analysis, and readiness exist as loosely connected layers. Data moves between tools. Interpretation depends on manual synthesis.

Vekta was designed as one connected performance modelling system.

It links:

A physiological performance model (Critical Power and W′)

Load components that separate workload and physiological cost

Session analysis that updates the model

Durability insight reflecting performance under accumulated demand

Training zones that adjust as capacity changes

Daily decision support grounded in current ability

Planning influences modelling. Modelling updates analysis. Analysis informs readiness. Readiness guides training decisions.

In practice, every session feeds back into the model. The model updates capacity. Capacity reshapes analysis. Analysis clarifies readiness. Readiness guides the next prescription.

The difference is not cosmetic. It is architectural.

What You See and Receive in Vekta

The system is visible inside the product. It is not theoretical.

When you connect your training data and upload sessions, you receive:

A performance model that is not one number

Critical Power (CP) and W′ are displayed as distinct components of performance rather than collapsed into a single threshold. This changes how intervals are prescribed and how performances are interpreted.

Load components that explain impact

Instead of collapsing stress into a single blended score, Vekta separates mechanical workload (Volume) from effort distribution (Intensity). At the session level, these components describe what was done and how it was distributed. Over time, they accumulate into Load and Strain, distinguishing total training demand from accumulated physiological cost.

Durability insight under demand

Durability views show how performance holds as sessions accumulate, connecting training data to long-event execution where late-session output and fatigue resistance matter most.

Training zones aligned with current ability

Zones are not static settings that require manual resets. As meaningful performance data appears, capacity estimates update and zones recalibrate to reflect current ability.

Session analysis linked to the model

Each session is analysed in the context of your current performance model. You can see what changed, what was stressed, and how that affects next decisions rather than only collecting a file and a score.

Artificial Intelligence as
Structural Support

Artificial intelligence in Vekta does not replace coaching. It performs the structural tasks that keep the performance model accurate and current.

AI operates on top of the physiological performance model rather than independently of it.

Detecting meaningful performance change as sustained shifts emerge in session data

Updating capacity estimates when warranted

Identifying patterns across sessions and weeks

Highlighting signals that matter while filtering noise

Producing structured session summaries to reduce review friction

AI surfaces patterns. Coaches and athletes apply judgement. Technology amplifies decision making. It does not replace it.

What This Changes in Practice

What This Changes in Practice

Architecture only matters if it improves daily decisions for both coach and athlete.

Architecture only matters if it improves daily decisions for both coach and athlete.

Clearer prescription and interpretation

By separating sustainable capacity (CP) from high-intensity capacity (W′), training decisions reflect actual physiological structure rather than a single FTP anchor. This improves pacing strategy, interval design, and identification of limiting factors.

Better weekly decisions

Separating Volume and Intensity allows you to understand whether training stress is driven by total workload, intensity density, or both. As these accumulate into Load and Strain over time, you can see whether adaptation is driven by volume progression, intensity distribution, or accumulated physiological cost.

Training that connects to long-event outcomes

Durability analysis makes late-session performance observable rather than assumed. This strengthens preparation for long races and demanding blocks where repeatability matters.

Alignment with current capacity

Because capacity estimates and zones update as meaningful data appears, decisions are based on present ability rather than outdated thresholds.

How Vekta Differs from Traditional Platforms

Most traditional training platforms centre intensity around FTP and express load through a single aggregated stress metric. Others focus primarily on analytics exploration.

Both contribute value.

Vekta connects modelling, planning, and interpretation into a single coherent performance modelling workflow, so insight does not require stitching together separate tools.

Vekta vs TrainingPeaks

TrainingPeaks is widely used for structured training planning and performance tracking. Its intensity framework centres around FTP, and load is typically expressed through composite stress scoring.

Vekta differs structurally in how performance capacity, load, and adaptation are modelled and applied.

Performance model

TrainingPeaks uses FTP as a primary intensity anchor.

Vekta uses Critical Power and W′ to model sustainable output and finite work capacity above it.

Load interpretation

TrainingPeaks aggregates training load into a composite score.

Vekta separates Volume and Strain, distinguishing mechanical work from physiological cost.

Model evolution

In TrainingPeaks, threshold updates are manual.

In Vekta, capacity and zones update automatically as meaningful performance data is detected, with AI highlighting when changes are significant
