For real-life runners. Ask whenever you want — your coach is available in the app, not monitoring you in the background.

My easy pace feels slower lately. Am I losing fitness?

Not necessarily. Heat, hills, fatigue and recovery can all affect a run. Look at the pattern across comparable efforts, not one day.

The foundation of better running

A stronger aerobic base changes everything.

Zone 2 is a way to build repeatable aerobic work into a life that’s already full.

With patient, consistent training, runners may find they can:

  • 01
    Run faster at the same effort

    Notice how a familiar easy effort changes over time.

  • 02
    Go further

    Build the endurance to stay comfortable for longer.

  • 03
    Develop cardiovascular fitness

    Make room for regular aerobic training in your week.

  • 04
    Recover and train consistently

    Balance easier days with harder efforts and rest.

  • 05
    Become a better runner

    Keep learning from the training you can sustain.

Training responses vary. These are possible benefits of consistent aerobic training, not guaranteed outcomes.

AN EXAMPLE CONVERSATIONILLUSTRATIVE
Runner

My heart rate was higher than usual and I felt tired on my easy run. Should I be worried?

Coach

One run can’t tell the whole story. Heat, hills, hydration, stress, fatigue and sensor readings can all play a part. If you feel unwell, stop and seek appropriate medical advice. Otherwise, it may help to compare how you felt and recovered across similar runs.

Example only. This does not represent an analysis of a real run or a medical assessment.

Available whenever you choose to open the app and ask. No proactive outreach, real-time monitoring or human 24/7 supervision.

Coaching that evolves with you

Every run is a conversation.

Your training is a loop, not a one-off prescription.

  1. 01

    Run

    Go out and run in a way that fits your day.

  2. 02

    Review

    Bring your Strava running data into view.

  3. 03

    Talk

    Ask your coach about a session or a pattern.

  4. 04

    Adapt

    Use the perspective to make your own next choice.

Every run informs the conversation. Every conversation helps shape the next run.

The app offers guidance and reflection; it does not automatically change a training plan or prescribe your next workout.

Our coaching philosophy

Kill the Plan. Keep the Progress.

Your week won’t always match the calendar. Work runs late. Sleep is short. The weather turns. That’s real life, not failure.

Keep the useful structure, lose the rigid schedule. Talk through what changed, consider how you’re feeling and make a sensible choice for yourself.

No guilt for a missed run. No catching up. Just progress that can make room for life.

Your aerobic fitness, made visible

See your aerobic engine getting stronger.

Explore useful patterns in the running data you choose to bring in. No single metric tells the whole story.

Zone 2 pace

See how pace compares across efforts at a similar heart rate or perceived effort.

Heart-rate drift

Notice how heart rate responds as a run goes on, with context for the day.

Time in Zone 2

Understand how much of a run sits in your intended aerobic range.

Training balance

Keep easy running, harder efforts and recovery in view together.

Stops and pauses

Consider interruptions when making sense of pace and heart-rate patterns.

Long-term progress

Look across weeks and months, not just one unusually good or difficult run.

These are the kinds of patterns to explore, not a display of your personal data. Heart-rate readings and zone definitions vary; context matters.

A simple idea, with nuance

What is Zone 2 running?

In everyday running, Zone 2 usually means a relatively easy, sustainable aerobic effort. You can often speak in sentences and keep the effort controlled.

Zone labels differ between watches and training models. The number alone doesn’t tell the whole story — your breathing, how you feel and the context of the run matter too.

For everyday runners

Whatever your pace, build a better aerobic base.

01 / BEGINNING

New to running

Find a manageable effort and build your routine gradually.

02 / IMPROVING

Getting faster

Put easy days in perspective while you work towards a quicker pace.

03 / PREPARING

Training for a race

Grounded in training science

Proven principles. Personalised to you.

Aerobic training principles have been explored across decades of exercise and endurance research. We use that broader knowledge to shape a practical coaching experience for everyday runners.

We don’t claim a watch can measure clinical heart health, diagnose a condition or guarantee a result. Training responses are individual, and useful progress takes time.

A question many runners ask

How do I know if my running is making me fitter?

Zone 2 Running Coach grew from a familiar frustration: wanting to build endurance without another rigid plan or another pile of charts without useful answers.

It brings your Strava running data and a coach-led conversation together, so you can explore what your training might be telling you and decide what feels right next.

It’s a tool for reflection and general training guidance — your running, your context, your choices.

General training guidance, not medical advice
