Scattered data
Activity data in one place, check-in data in another, race plans in a third. No system connects what the athlete did with how they felt with what's coming next.
Human-First Coaching Intelligence
One connected platform for the entire coaching relationship.
Sigwren replaces fragmented tools with a single system where readiness scoring, training planning, race intelligence, and AI assistants all talk to each other. Every AI decision shows its confidence level and can be overridden by the human in charge — whether that's a coach or a self-coached athlete.

Coach Dashboard
Morning triage: who needs attention, why, and what to do about it.
The Problem
Coaching tools that don't talk to each other.
Most coaches piece together a stack: a calendar tool for planning, a watch platform for data, a spreadsheet for load tracking, an app for messaging, and their memory for everything else. When you're managing ten athletes, context falls through the gaps. At twenty, it's unsustainable.
Manual scanning
Coaches start each day scrolling through every athlete looking for red flags. The important signals hide in the noise of routine data.
Lost context
The conversation three weeks ago, the twinge mentioned in passing, the training phase rationale. Critical coaching context lives in the coach's head or nowhere.
The Platform
Everything connected. Nothing duplicated.
Sigwren brings daily readiness, training planning, workout design, race intelligence, device data, and AI coaching into one platform where every piece of information feeds every decision.
Daily Readiness & Decision
Every morning: a readiness score from wearable data, check-ins, and training history. A clear recommendation: GO, MODIFY, or REDIRECT. With the reasoning behind it.
Season Planner & Calendar
Month-view calendar with periodisation phases, workout scheduling, and automatic push to athlete watches. Hundreds of ready-made templates, fully extendable — save your own and share within your practice.
Workout Builder
Quick builder for simple sessions, advanced builder for complex intervals with repeats, ramps, and drag-and-drop. Targets set as percentage-of-threshold adapt to each athlete automatically.
Race Intelligence
Upload any course file and get instant terrain analysis, segment breakdowns, and physics-based split predictions calibrated to each athlete. Find local training routes that match race demands.
AI Assistants
Alice guides athletes. Ada assists coaches. Both draw from doctorate-level coaching science across 13+ methodology world views. Use ours, extend them, or create your own. The AI helps you build and curate your knowledge.
Movement Analysis
Lab-grade movement screening without a lab. Athletes record themselves, the platform analyses joint angles and movement quality, and coaches get scored results with corrective programmes.
Device Connections
Garmin, Suunto, Polar, and more. Data flows in automatically. Workouts push to watches. Smart source selection lets athletes choose the best device for each data type.
Training Load & Zones
Six load methods in parallel, personalised zone profiles, threshold governance that alerts coaches when a retest is due. Cross-sport weighting for multi-discipline athletes.
Health & Wellness
Sleep, HRV, injury tracking, cycle awareness, muscle readiness mapping, rehabilitation plans, and nutritional fuelling intelligence. Everything feeds the readiness score.
Beyond the Engine
Sport demands more than fitness. Sigwren measures what actually matters.
A big aerobic engine isn't enough. Durability alone isn't enough. Race outcomes are shaped by dozens of capabilities — terrain handling, pacing discipline, fuelling execution, heat tolerance, strength endurance — and none of them work in isolation. Sigwren's Capability Module lets you pinpoint each one, measure it against specific race demands, and compare it to the world. Then train the gaps that actually change the outcome.
Pinpoint
Identify the specific capabilities that matter for each race and each athlete. Not generic fitness — the actual dimensions that influence the result.
Measure
Quantify each capability from training data, test results, and race history. See where the athlete is strong, marginal, or behind — with confidence levels.
Compare
Match athlete capabilities against race demands dimension by dimension. The gap analysis shows exactly what to train and what's already race-ready.
Deep Athlete Context
The system that actually knows each athlete.
Curated coaching knowledge is only half the picture. The other half is understanding each individual athlete deeply: their race history, their injury patterns, their equipment, their constraints, their goals. Sigwren builds and maintains a living context for every athlete — so when the AI says "switch to the treadmill today", it's because it knows you have one. When it adjusts your taper, it remembers your 100-miler last year and the calf strain from six weeks ago.
Training History
Every session, every race, every compliance score. The system knows what you've done, how you responded, and what worked.
Physical State
Injuries, muscle readiness, thresholds, movement scores, rehab progress. Not just today's snapshot — the full trajectory.
Life Context
Equipment, training availability, travel schedules, compromised periods. The practical constraints that shape real training decisions.
Human-First. AI-Supported.
No black boxes. Every decision transparent and overridable.
Sigwren's AI never makes decisions behind closed doors. Every recommendation shows its confidence level — exploratory, developing, or grounded — so you always know how much data backs it. Every output can be overridden by the human in charge, whether that's a coach managing a roster or an athlete coaching themselves.
Alice
Athlete-facing guide. Answers training questions, explains readiness scores, facilitates reflections. Always shows her reasoning. Athletes can ask "why?" and get a straight answer.
Ada
Coach-facing assistant. Surfaces priorities and drafts communication. Every response carries a confidence tier so coaches know whether the advice is tentative or backed by strong data.
Human Override
High-stakes advice is flagged for human review before anyone acts on it. The coach — or self-coached athlete — approves, modifies, or overrides. AI handles volume; humans handle judgment.
Race Day
From start line to finish line.
On race day, Sigwren becomes an execution platform. Athletes follow their plan. Crew members track progress. Everyone stays connected.
Race Execution
Mobile screen showing current segment, pace target, nutrition reminders, and next segment preview. Works offline in remote areas with sync when connectivity returns.
Adaptive Pacing
Fall behind plan? The system recalculates a recovery strategy across remaining segments. A revised plan, not a panic.
Crew Console
Shared-link page for crew at aid stations. No login needed. Shows athlete location, pace, and next expected arrival time.
Follower Tracking
Family and supporters follow race progress on a public page. Checkpoint arrivals, course position, and estimated finish time.
Built from fifteen years of real coaching.
The biggest challenge in coaching was never knowledge. It was context. Remembering race history. Tracking practical constraints. Reconstructing conversations. Connecting athlete signals to race demands.
Sigwren removes the memory, analysis, and workflow burdens that slow great coaches down. AI handles the heavy lifting so coaches can focus on judgment, relationships, and the craft of coaching.
