Athlete profile

For runner accounts there's an Athlete profile page under Settings, designed to power KULG Training Intelligence in providing personalised training guidance.

The profile includes the a Performance & physiology section as well as the HR zones.

HR zones

• You can see and edit your HR zones based on the 5-zone model, either by using max HR or customising your HR zones manually.

Performance & physiology

• You can add and manage key data, including your physical profile (weight, height, body fat %, resting HR), lab metrics (max HR, lactate threshold HR, VO₂max), threshold pace data, and hematology values (hemoglobin, hematocrit).

• Entries can be saved by date and edited or deleted at any time.

• Max HR, lactate threshold, and VO₂max are used to calibrate your heart rate zones. If this data is not available, zones are estimated from your activity history, unless you have set them manually. Where possible, use lab values, as VO₂max estimates from watches are often not reliable enough for precise analysis.

• This data is used to generate more tailored weekly and monthly AI insights and will power future adaptive training guidance. The more complete your profile and the more you add feedback to your activities on how you felt during training, the more precisely KULG can adjust recommendations to your individual physiology, performance, and recovery.

• For aerobic threshold (AeT), include heart rate corresponding to LT1 (first lactate/ventilatory threshold).

• For anaerobic threshold (AT), include both heart rate and pace corresponding to LT2 or the lower end of the threshold range.
