I am a runner and blogger by passion – at least in my spare time. Actually I am an architect, but I have been working in marketing for over 10 years. Therefore I know not only the world of runners, but also that of agencies and manufacturers.


Harlerunner is one of the major running blogs in Germany and is published in German and English. Since 2014 I write about running, my training and the necessary equipment – twice a week. The blog is SEO-optimized and reaches for almost all articles a ranking on the first search page at Google.


I like to discover new products, am curious to try them in training and then share my experiences on the blog. I allow myself about 4-8 weeks for this. Support through collaborations is always indicated clearly.

There is no interest in advertisements, lotteries, external content, hidden advertising or content regulations.

I will provide you with a detailed media kit on request:

Hi! It’s me, the Harlerunner.

This is where Thomas Pier writes about running and (much more than just the necessary) equipment. I don't run particularly fast or far. But I like to share my experiences as an ambitious recreational runner, curious early-adopter and as my own trainer.

I am happy about every digital contacting - but even more so about every kilometer run together.
