Weather: warm and sunny, 23 to 27 degrees
Trail: dry, downhill a little slippery as there is some sand on the trail. There are no single trail sections. Hence easy to run. The trail seems to be a well-known hiking trail, so busy on Sundays.
Fun factor: The art in the garden of the castle (starting point) is worth a visit. In addition, the UNIMOG museum at the trail head is also a nice spot for kids.
