Zone 2 Training: The Slow Work That Makes You Fast

Most amateur runners and cyclists go too hard on their easy days and not hard enough on their hard days. The fix is slower than you'd think. This guide explains the physiology in plain English, shows you three ways to find your own Zone 2, and gives you weekly plans you can start on Monday.

Pace notes

Small habits, big returns

Not everything needs a 4,000-word guide. These are the small, well-supported habits we keep coming back to.

Sleep before supplements

Seven to nine hours a night does more for recovery than anything you can buy. Protect your sleep in heavy training weeks.

Increase slowly

Big jumps in weekly training load are one of the most common triggers for overuse injuries. Build gradually and take an easier week every three or four.

Eat before hard sessions

A banana or a slice of toast 30 to 60 minutes before intervals makes them feel easier and helps you hit your targets.

Lift twice a week

Two short strength sessions reduce injury risk and improve running economy. Twenty minutes is enough to start.

Warm up properly

Ten minutes of easy movement plus a few short, faster efforts prepares you better than static stretching before sport.

Practise your nerves

Use your breathing and routine in training, so they're automatic when it matters on match day.

Myth check

Things you've probably been told

A lot of sports advice gets passed around without anyone checking it. Here are four we hear often.

MythEvery session should leave you exhausted.

What the evidence saysMost endurance athletes improve faster when the majority of sessions are easy. Exhaustion every day usually means stalled progress and higher injury risk. Why easy training works.

MythYou have to eat protein within 30 minutes of training.

What the evidence saysYour daily total matters far more. A normal meal within a couple of hours is fine for most people. Our fuelling guide.

MythRest completely until the pain is gone.

What the evidence saysFor most overuse injuries, reduced activity that doesn't aggravate symptoms works better than complete rest. The shin splints guide shows how.

MythIf you're nervous, just calm down.

What the evidence saysTrying to force calm often backfires. Reframing nerves as excitement tends to help more. The pre-game nerves guide.

Who this is for

Every sport. Same body.

We write for the person who runs before work, plays five-a-side on Thursdays, swims on Sunday mornings or is training for a first triathlon. You take your sport seriously, but it isn't your job.

So the advice has to fit around real life. We assume you have limited time, no sports scientist on call, and a body that's a few years older than it was when you started.

The physiology of a weekend footballer and a marathoner has more in common than you'd think. Both need an aerobic base and some strength. Both need to eat and sleep enough. Both need to manage nerves on the day. Whatever your sport, the four lanes on this site apply to you.

We also write with coaches and parents in mind. If you look after a junior team or a running group, our guides are meant to be shared, and they're written so a 15-year-old can follow them.

How we write

No hype. No miracle cures.

Health and fitness writing is full of overconfident claims. We try to do the opposite: say what the research shows, how strong it is and where the gaps are.

Read our editorial policy

  • We cite sourcesEvery guide lists the studies and position statements it draws on, so you can check our work.
  • We rate the evidenceWhen advice is well established we say so. When it's a sensible best guess, we say that too.
  • We don't sell curesNo affiliate supplements, no detox plans and no sponsored articles. Ads are clearly labelled and kept separate from the writing.
  • We updateWhen new research changes the picture, we rewrite the guide and change the date at the top.
  • We know our limitsOur guides are education, not diagnosis. We tell you clearly when to see a professional.
A note from the editor

Why another sports health site?

There's no shortage of sports health content online. The problem is that so much of it lands at one of two extremes. Either it's written for scientists, accurate but impossible to turn into a plan for Tuesday's run, or it's written for clicks, simple and confident and often wrong.

We wanted something in the middle. Guides long enough to cover a topic properly, written so you can actually use them, and honest about what's known and what isn't. Each one starts with the research and the expert consensus, and ends with something you can do this week.

That approach is slow. It's why the site launched with four guides rather than forty. We'd rather each article be the one you bookmark and send to your training partner than one more post that repeats what everyone else says.

If you spot something we've got wrong, or there's a question you'd like answered, please tell us. Reader questions shape most of what we write next, and corrections make every guide better.

Thanks for reading.

Questions

Before you start reading

Quick answers about the site, the advice and how to use it.

Who writes Sports Health Guide?

A small independent editorial team. We base every guide on published research and expert position statements, list our sources at the end of each article and update guides when the evidence changes. Read our editorial policy for details.

Is this medical advice?

No. Our guides are general education to help you understand your body and ask better questions. For injuries, symptoms or medical conditions, see a qualified doctor or physiotherapist.

I'm a complete beginner. Where should I start?

Start with the Zone 2 training guide. It explains how to build fitness safely, and the easy-effort approach suits beginners well.

How often do you publish?

One long guide at a time, roughly every week or two. We'd rather publish less and get it right.

Why are there ads on the site?

Advertising pays for the research and writing and keeps every guide free to read. Ads are labelled, and advertisers have no say over what we write.

Can I suggest a topic?

Yes, please do. Use the contact page to tell us what you want to read about. Reader questions shape most of our upcoming guides.
