About Zone Pro: HR Power Pace
Zone Pro is a unified training zone calculator for triathletes and endurance athletes, built around the methods coaches actually use.
Heart rate zones:
- Karvonen method (percent heart rate reserve) from your max and resting heart rate
- % Max HR 5-zone model when you only know your max heart rate
- LTHR-based 6-zone model from your lactate threshold heart rate
Cycling power zones:
- Classic Coggan 7-zone model from your FTP (Functional Threshold Power)
- Or enter your 20-minute test average and let the app take 95% as FTP
Running pace zones:
- 5-zone model calculated from your threshold pace, in min/km or min/mile
Swim CSS zones:
- Critical Swim Speed from a 400/200 time trial in meters or yards, converted into pace-per-100 training zones
Check a value:
- Type a reading from your watch on any tab and see which zone it falls in, highlighted in the table
Test log:
- Save a dated snapshot of each threshold after a test, see the change since last time, and re-apply an old result
- Share or copy all your zones at once
Enter your test numbers once and see every zone, for every discipline, laid out clearly with exact ranges, not vague guesses. Switch calculation methods to match what your coach or training plan uses.
Zone Pro works entirely offline and keeps your data on your device. No account, no subscription, no ads.
This app performs standard, published training-zone calculations for educational and training-planning purposes. It is not a medical device and does not replace advice from a coach or physician.
