i did this run unsupported. Hopefully in a good time for a long FKT.
I had to make a little different route for about 1000m, because the bridge over the A114 was under construction. but it was very similiar.
It is a very nice trail for living in Berlin most of it is on concrete streets but sometimes it is a real trail and most of it without traffic. i had three red traffic lights where i lost some seconds.
All the Best
Thanks for motivation Thorge!
Maybe we should team-up for Berliner Mauerweg one day? ;)
