On this tour Braunsbetra is a big construction site. At the construction fence bypass you come to the lower path and then later the steep stairs again. Not for older people, so on the fence to the right!
Driving counter-clockwise I find 64 years old not so great. It is not as steep as in the clockwise direction but for miles uphill. The increase is steeper but short in the clockwise direction. Since you can push the bike well.
