By default, your Stages Link account is set to a 6 zone system for heart rate and power. Number of zones and zone ranges can, however, be modified and customized to your preference.

Zone Name Watts % Threshold HR % Threshold Effort Level RPE
1 Recovery < 65% < 64% Easy 1-2
2 Endurance 66 - 80% 65 - 84% Moderate 3-4
3 Tempo 81 - 90% 85 - 91% Moderate 5-6
4 Threshold 91 - 104% 92 - 99% Moderate/Hard 7-8
5  VO2 105 - 120% 100 - 105% Hard 9
6 Anaerobic > 121%  > 106% Maximal 10


Custom Zones


To update your zone settings for power and heart rate, click on your name in upper right corner and go to: Account > Zones

  • To add a zone to change your default setting to 7 or 8 zones, click +ADD RANGE
  • To update the range, simply change the min and max percentages and hit Save


Note: If you have already began a training plan, modifying the training zone ranges may have an adverse affect on the prescribed zones for your generated training plan, as modifying these zones can change the prescribed heart rate and power to fall outside of that which is intended by the training plan. At this time we do not recommend adding additional zones while using Stages Link generated training plans. For 7-zone workouts, we recommend using the workout builder to create your own or modify existing workouts to align with a 7-zone system.
