Active development · Private beta preparation

Training that adapts to reality.You stay in control.

Kestivo connects your target race, real availability and completed training to the next planning decision. It builds a long-term Training Roadmap, drafts the next structured week, and lets you review what changes before it becomes your plan.

Built first for triathletes and self-coached endurance athletes. Built for real training data, not a perfect calendar that never survives contact with real life.

The real problem

Training plans work until real life happens.

Work runs late. A swim disappears. A ride is harder than planned. An unexpected race creates a completely different training load. The useful question is not whether yesterday's calendar was perfect. It is what should happen next.

1 A workout is missedDo not blindly push it into the next empty slot.
2 An extra session appearsIt should count as training evidence, not disappear outside the plan.
3 The week changesProtect the purpose of the training block instead of trying to preserve every old workout.

Long-term direction

Know where you're going.

A useful week needs a reason. Kestivo anchors weekly planning to a race-oriented Training Roadmap so today's workout sits inside a clear progression toward race day.

  • See the current training phase instead of only isolated workouts.
  • Keep the target race authoritative while the weekly details evolve.
  • Connect weekly decisions to long-term progression and race specificity.
Working internally
Plan meets reality

What actually happened matters.

Planned training and completed training are different facts. Kestivo keeps both visible, so the next planning cycle can use what you really did rather than pretending the original calendar happened perfectly.

  • Planned workouts preserve the original training intention.
  • Completed activities preserve the factual training evidence.
  • Confident matches can be shown together without rewriting either history.

Controlled adaptation

When reality changes, the next week should too.

In this real Kestivo generation, an unexpected middle-distance race created more training stress than the week originally expected. The completed race became context for a recovery-focused next-week draft.

  • Completed training becomes planning context for what comes next.
  • Recovery is treated as training, not as a failure to fill the calendar.
  • The generated week remains a proposal for athlete review.

Why Kestivo

Three ways a training plan can respond when life gets in the way.

Kestivo is deliberately positioned between a plan that never changes and automation that can make the new calendar the answer by default.

Static plan

You repair the week yourself.

The original schedule stays fixed even when the training evidence changes.

  • Predictable
  • Easy to understand
  • Manual repair after disruption
Automation-first

The system changes the plan for you.

Convenient when it works, but the athlete can lose sight of what changed and why.

  • Low planning effort
  • Fast replanning
  • More authority delegated to the system
Kestivo

The system proposes. You decide.

New evidence can change the recommendation without silently changing the authoritative training week.

  • AI-assisted planning
  • Deterministic validation
  • Athlete review before activation
Private beta status

The core planning loop is working internally.

Kestivo already connects athlete context, a race-oriented Roadmap, weekly generation, review and activation, completed-activity ingestion, planned-versus-actual presentation and persisted training-load/physiology evidence. Current work is reliability, controlled adaptation and execution bridges before external athlete rollout.

Built for real training dataCompleted activities can feed the planning and physiology pipeline.
Manual control stays permanentPlanning and completion remain usable when an external bridge is unavailable.
Private by designHealth and training data is not sold or used for advertising.
Completed activity ingestion

Working internally through the current iOS health-data bridge.

Device execution bridge

In progress. Kestivo remains useful while direct external access is being finalized.

Private beta

Next step is a small controlled athlete rollout after planner and reliability gates are satisfied.

The principle

AI drafts. Kestivo validates. You approve.

Intelligence should reduce planning work without hiding the decision from the athlete.
