Keep running, without injuries.

I'm a sports physiotherapist in Haarlem and have worked with runners for fifteen years. On this site I share what I explain in my practice every week.

About me

Most runners who come to me have done too much too soon. That's not weakness, that's enthusiasm. My job is to get them going again and explain how to prevent a next time.

What I say in the treatment room, I write down here. That way you can read it again, and someone I'll never meet benefits too.

  • Running coach at an athletics club in Haarlem
  • Speaks at events for coaches and GPs

What I tell runners

The three topics I get asked about most.

Building up without setbacks

Your fitness improves faster than your tendons and bones. So a session can feel fine while your body isn't ready for the next step yet.

  • Increase one thing per week: distance, pace or number of sessions.
  • Deliberately plan an easier week every fourth week.
  • Alternate between hard and soft surfaces.

If you're tired in a way that a rest day doesn't fix, skip a session. That makes you stronger, not weaker.

Pain while running: carry on or stop

Stiffness that eases within ten minutes is usually no reason to stop. Pain that gets worse as you run, or that changes your stride, is.

If in doubt, walk home. One missed session costs you nothing. Running on through an early injury often costs you weeks.

Starting again after a break

After a few weeks off you've lost more than you think. Start at half of what you used to do and alternate running with walking.

Give yourself as many weeks to come back as you were away. It feels slow, but it's the fastest way back.

This page gives general information and does not replace treatment. If a problem persists, have it looked at.

News from my field

Every Monday morning Claude looks up last week's news and puts it here, with the source. I don't have to do a thing.

Updated on Monday

More beginner runners seek help in autumn

Sports doctors see a peak in overuse complaints around this time every year among people who have just started. Building up more gradually turns out to be the main advice.

Research into cushioning in running shoes

A new study compares shoes with a lot and a little cushioning. The difference in injuries turns out to be smaller than manufacturers suggest.

Strength training increasingly part of running plans

Coaches are more often adding two short strength sessions a week. Runners who keep that up drop out less often.

Iris can't code and has no web designer. She asked Claude, in plain language.

The siteI'm a sports physiotherapist and want a home for my knowledge about running injuries. Make a site with who I am, the three topics I get asked about most, and a news page.
The newsEvery Monday morning, find last week's news about running injuries, summarise it briefly and add the source.

Claude writes and builds. Waterbloom makes sure the site lives at its own address and that the news refreshes itself every week, even if Iris doesn't log in for a month.
