Private beta live · Selected athletes testing now
Training that adapts to reality.Every change stays yours to approve.
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.
Training Week · real Kestivo product state presented as a marketing composition
Drag-and-drop rescheduling is available in the calendar.
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.
A workout is missedDo not blindly push it into the next empty slot.
An extra session appearsIt should count as training evidence, not disappear outside the plan.
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.
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.
Real development example: a completed middle-distance race became context for the next weekly plan.
Controlled adaptation
What happened changes what comes next.
In this real Kestivo generation, an unexpected middle-distance race created more training stress than the week originally expected. That completed race became evidence for a recovery-focused next-week proposal.
- Completed training becomes planning context for what comes next.
- Recovery is treated as training, not as a failure to fill the calendar.
- The next week remains a proposal until the athlete approves it.
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.
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 proposes. You decide.
New evidence can change the recommendation without silently changing the authoritative training week.
- Completed training informs the next proposal
- Hard constraints are checked before activation
- Athlete approval stays explicit
Private beta status
The private beta is live.
A small group of selected athletes is now using Kestivo in real training. The private beta covers the core coaching loop from Roadmap and weekly generation through review, completed-training evidence and planned-versus-actual feedback. Current work is driven by beta feedback, reliability and stronger execution bridges.
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 in the private beta through the current iOS health-data bridge.
Device execution bridge
In progress. Kestivo remains useful while direct external access is being finalized.
Private beta

Kestivo proposes. You approve what changes.
Planning technology should reduce the work without hiding the decision from the athlete. Kestivo uses AI to help generate plans and explanations, while proposals are checked and reviewed before activation.
