Training Zones Explained
Training, August 23, 2019
Understand Foot Traffic’s five training zones and learn how to use effort, heart rate, pace and power to get the intended benefit from each session.
Training zones help you understand the purpose of a workout and control how hard you work. At Foot Traffic, we mainly describe training using five zones, from very easy recovery through to short, hard efforts.
The goal is to deliver the right effort for the session. Going harder isn’t automatically better, especially when it compromises the training that follows.
How the five zones should feel
| Zone | Effort | Practical guide |
|---|---|---|
| Zone 1: Recovery | Very easy | Relaxed breathing, little strain and easy conversation. Keep recovery sessions light. |
| Zone 2: Endurance | Easy and controlled | You can hold a comfortable conversation. The effort should feel repeatable, although fatigue can build during longer sessions. |
| Zone 3: Tempo | Steady and purposeful | Breathing is deeper and conversation becomes shorter. This is useful work when prescribed, with a greater recovery cost than easy endurance training. |
| Zone 4: Threshold | Hard and controlled | Concentration is required and talking is limited. Follow the prescribed effort, repetition length and recovery. |
| Zone 5: High intensity | Very hard | Short, demanding efforts with little capacity for conversation. These sessions need appropriate preparation and recovery. |
These descriptions help you recognise the effort. Your individual heart-rate, pace and power ranges should come from the method used in your training plan.
Zone systems vary, so a numbered zone on your watch may not match the same number in your programme.
Using effort, heart rate, pace and power
Perceived effort is your assessment of how hard the exercise feels. Consider your breathing, muscular effort and ability to talk. If your programme uses a 0–10 RPE scale, 0 represents rest and 10 represents maximum effort. These ratings are guides, rather than exact equivalents for every training zone.
Heart rate shows your response to the work. It is useful during steady exercise, but takes time to respond when intensity changes. Heat, hydration and fatigue can affect it. Avoid pushing harder at the start of an interval simply because your heart rate hasn’t reached the expected range.
Pace helps guide swimming and running, particularly in consistent conditions. Hills, wind, surfaces and open-water conditions change the effort required to maintain a particular pace. Let pace vary when necessary to achieve the intended effort.
Power helps control cycling output when speed changes with terrain or wind. Running power is an estimate from your device, so use it consistently within that system.
Read the workout to understand which measure should lead. Use the other measures to check your response.
Why easy training matters
Easy training supports endurance and allows you to accumulate consistent work without every session carrying a large recovery cost.
If an easy run becomes hard on a hill, shorten your stride, slow down or walk where appropriate. On the bike, use your gears and allow your speed to change.
Keep easy sessions easy enough to support the rest of your programme.
Tempo has a place
Zone 3 is useful when it serves the purpose of the plan. Tempo work can develop sustained effort and support preparation for endurance racing.
The problem comes when you repeatedly turn easy workouts into tempo sessions without allowing for the extra fatigue. Complete tempo work deliberately, with the duration and recovery your programme calls for.
There is no single percentage split between zones that suits every athlete. Your balance depends on your experience, event, training phase and ability to recover.
When the numbers don’t agree
If familiar pace or power feels unusually hard, consider the conditions and your recent training. Ease back when needed to preserve the session’s purpose.
If heart rate looks unexpectedly low or high, check the sensor before reacting. Don’t force the effort to chase a questionable reading.
Record what happened, including conditions and perceived effort. Repeated mismatches are worth discussing with your coach.
Keep your zones current
Review your zones periodically using suitable testing and evidence from training. Swimming, cycling and running need their own settings, and your watch, bike computer and training platform should use the intended method.
A threshold value is a useful training reference, rather than a perfect prediction of what you can sustain on every day.
If you’re unsure whether your targets are right, ask your coach. The best zones help you train consistently, understand the work and recover for what comes next.
