I ran from South to North and back. My goal was to be faster than the previous FKT on the first way and push as hard as possible on the way Back. Had strong headwinds on the way Back, but overall conditions could have been worse this time of a year.
Route is well marked, and obvisiouly there are small variations possible, depending on the direction you choose, as you can see in the GPX Track. I followed the signs all the time.
Was much more hilly then expected, but i enjoyed it a lot.
Have fun next runner.
