Endurance Signals · the founder's view

A coaching tool that learns how your club works.

Data-driven decision support and individualised club plans, for triathlon and endurance clubs and the coaches who run them.

Who it is for

Built with a club, for clubs.

  • Club coaches

    Write one plan for the club. Every athlete gets their own version, and you see attendance, flags and who needs a conversation.

  • Independent coaches

    HRV-guided blocks, workout analysis and athlete check-ins in one place. Query your roster from Claude through a read-only connection.

  • Athletes

    Follow the club plan, have it adjusted to your week, or do your own thing. Your data, explained in plain language.

What is inside

Computed in code. Explained by AI. Decided by the coach.

Phases, zones, weekly load and race spacing come from deterministic engines. The model writes the explanation and drafts sessions from your library.

  • Decision support

    HRV Advisor, daily check-in and workout analysis, triaged into a short list of flags.

  • Plans

    Plan Block with "Adjust for me", the Annual Plan season wheel, and Strength Coach.

  • Metabolic

    Profiles and zones from recent peak power, using the FuelingSense engine.

  • Club and integrations

    Weekly club email, carousel studio, intervals.icu and Garmin.

Principles

The coach stays in charge.

  • Deterministic numbers

    Training phases, zones and flags are calculated, never invented by a model.

  • Athlete choice

    Personalisation is opt-in. Athletes choose the club plan, an adjusted plan, or their own.

  • 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 your watch.
