Endurance SignalsCoaching platform for endurance clubs and coaches
Turn the club plan into every athlete's plan.
Endurance Signals reads each athlete's HRV, check-ins and sessions, fits the club's training block to their week, and shows the coach who needs a conversation. Numbers are computed in code; AI explains them; the coach decides.
Who it is for
One plan in, one plan per athlete out.
- Club coaches
Write one block for the club. Athletes follow it, have it adjusted to their week, or train their own way. Race weeks and key club sessions stay fixed.
- Independent coaches
HRV-guided blocks, workout analysis and morning check-ins for each athlete, with a short daily list of flags. Query your roster from Claude through a read-only connection.
- Athletes
Your club's plan, fitted to your schedule, biometrics and goals, with your data explained in plain language.
Features
Decision support, individual plans, club tools.
Training phases, zones, weekly load and race spacing come from deterministic engines. The model writes rationale and drafts sessions from the coach's library. Terms are explained in the glossary.
Decision support
HRV Advisor
Each athlete's normal range, anomalies and next-block recommendation, race-aware, with a review of any past period.
Decision support
Daily check-in
A short morning questionnaire with fixed flag rules and a named check-in coach. Concerns stay open until a coach resolves them.
Decision support
Workout analysis
Planned against completed for each session, plus zone-restricted efficiency and durability alongside HRV.
Plans
Plan Block
Club and athlete plans, and "Adjust for me", which reads the athlete's goals, motivation and commitments.
Plans
Annual Plan
A season wheel built from the club road map, with blocks that follow the club plan as it changes.
Plans
Strength Coach
Screening, phase selection and sessions drawn only from a vetted exercise library.
Metabolic
Metabolic profile
VLamax, VO2max and zones from recent peak power, using the FuelingSense engine.
Club
Club tools
A weekly club email written from the plan and sent from the club's own address, and a carousel studio for social posts.
Integrations
intervals.icu and Garmin
Activities, wellness and HRV in; structured workouts out to the watch and on to Zwift.
Principles
The coach stays in charge.
- Calculated, not generated
Anything that becomes a training instruction is computed by code and can be traced to its inputs.
- Athlete choice
Personalisation is opt-in, never automatic.
- Consent by tier
Athletes decide what is shared, and sensitive data has its own switch.
- Works alongside
A coaching tool, not a replacement for intervals.icu, TrainingPeaks or a watch.
