How to use this library

Read in any order

Every guide on Sports Health Guide is written to stand on its own. You don't need to read them in order, and you don't need any background in sports science.

If you're new to structured training, start with Zone 2 training. It introduces ideas, like training load and easy versus hard effort, that come up across the site.

If something hurts, go straight to the Recovery lane. Our shin splints guide includes a step-by-step return-to-running plan that also works as a template for other overuse injuries.

If you have a big event coming up, read the fuelling guide and the pre-game nerves guide together. Between them they cover most of what goes wrong on race day.

Each guide opens with a short summary, so you can get the main points in a minute and come back for the detail later. The contents list on the left (or at the top on a phone) lets you jump straight to the section you need.

Myth check

Quick corrections

A few of the most common bits of bad advice we see, with links to the guides that go deeper.

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.
