About me

I'm part of the team that runs this website theCrag (along with Simon Dale, Campbell Gome, Brendan Heywood and Ulfi)

So if you've got ideas or bugs please let us know:

Especially any of the little things that bug you but have probably just slipped through and would be easy to fix.

I started climbing as a child in the magnificent sandstone towers in Saxony (Germany) and meanwhile I climbed at many crags in Europe for decades. I was one of Europe's first power users on theCrag and became a team member in 2015. My work at theCrag is mainly data driven, for example to maintain the structural content. Good for you to know: I can help you with importing your historic ascents or we can work out a way how to import entire new crags if you are a route setter or guidebook author. In case you see any copyright infringements on theCrag I would be happy if you contact me – so that I can solve them.

We live in Zurich - Switzerland.
