BaseLayer
Adaptive aerobic training for runners.
BaseLayer uses your heart rate and run data to tell you exactly how much productive aerobic work to do today. It learns from you, adapts to your current condition, tracks progress live, and vibrates when you’ve done enough to improve.
It works alongside your favourite watch or run tracker, helping you build aerobic fitness without overtraining, and saves progress across the day.
Train less randomly. Build fitness intelligently.
How BaseLayer works
BaseLayer helps runners develop aerobic fitness by guiding training load in real time. Its core fitness signal is grade‑adjusted pace divided by heart rate. If you can run faster at the same heart rate or hold the same pace at a lower heart rate, your aerobic fitness is improving.
Your first run calibrates the system. After that, BaseLayer sets your modelled capacity (your current aerobic state) and your daily target (how much productive work you can do today). It adapts continuously to your current condition and training response using run and heart rate data.
You have 24 hours from the start of a session to complete your daily target. You do not need to finish it in one go. BaseLayer automatically saves progress, so you can return later and continue.
BaseLayer is built for one job: developing your aerobic base. It does not replace long runs or speed sessions; it strengthens the foundation that makes them effective.
It runs quietly in the background while your watch or favourite run tracker records the session. BaseLayer decides when you’ve done enough productive work to improve fitness.
Connect a Bluetooth heart rate monitor, complete one calibration run, then follow your live progress and stop when your daily target is reached. Over time, track your improvement on the fitness graph.
BaseLayer supports Bluetooth heart rate monitors that broadcast the standard BLE heart rate profile, including most chest straps and some optical armbands. Garmin watches may also work when set to broadcast heart rate.
