Well, it is not 200 km, which is realy impressive,
but just 30 km to circle one of our 8 km long mountain lake:
With a monofoil you have to keep your trips small , but always enjoy a lot to pass every corner of our lakes and to folow the outline as far as possible.
It's still impressive how far you can reach into every lee, which years before on twintip no one would have ever believed.
