Benefits of Zone 2 running

Benefits of a stronger aerobic engine

Zone 2 running trains your aerobic system — the system that uses oxygen to help fuel sustained effort, from 5K to marathon and beyond.

Consistent Zone 2 aerobic training can help you:

  • 01
    Run faster at the same effort

    Improve your pace without continually increasing your heart rate.

  • 02
    Go further

    Develop the endurance to run comfortably for longer.

  • 03
    Build cardiovascular fitness

    Support a stronger, more efficient aerobic system.

  • 04
    Recover and train consistently

    Build a foundation that supports sustainable training.

  • 05
    Become a better runner

    Whether your goal is your first 5K or your next marathon, aerobic fitness matters.

Expert coach always available

Your Zone 2 coach available 24/7

Imagine having a running coach who knows your training, understands your progress and is there whenever you need advice.

Your Zone 2 coach connects to your Strava running history, helps you understand your easy aerobic runs and gives you personalised feedback on your training.

Not sure if you’re improving? Ask. Heart rate higher than expected? Talk it through. Feeling tired or struggling to fit runs into your week? Work out what to do next.

It’s not just about recording your runs. It’s about having a conversation that helps you become a better runner.

AN EXAMPLE CONVERSATIONSAMPLE
Runner

My heart rate was much higher than usual today. Am I losing fitness?

Coach

Not necessarily. One run doesn’t mean your fitness is declining. Heat, fatigue and recovery can all affect heart rate. Let’s look at your recent easy runs and see whether there’s a trend before changing your training.

Runner

I slept badly last night too. Should I still run tomorrow?

Coach

We can take that into account. If you’re still feeling tired, an easier session or a rest day may be more useful than pushing through.

Our coaching philosophy

Kill the Plan. Keep the Progress.

Life doesn’t follow a training plan.

Some days you’re tired. Some weeks work gets in the way. Sometimes your running improves faster than expected. Traditional training plans don’t always account for that.

Your Zone 2 coach helps you fit aerobic training around what’s actually happening, rather than blindly following a schedule written weeks ago.

Missed a run? Talk to your coach. Feeling exhausted? Discuss your recovery. Ready to do more? Understand whether it’s the right time.

The goal isn’t to complete the plan. The goal is to improve your aerobic engine and become a better runner.

Adaptive coaching

You are not slave to a running plan

Your training doesn’t stand still. Neither should your coaching.

Your Zone 2 runs help build your aerobic base. Your running data helps your coach understand how that fitness is developing, while every conversation adds context the numbers alone can’t explain. Together, they help you understand your progress and decide what comes next.

  1. 01

    Connect Strava and bring your running data into the app.
