This ride is called Mellow Mushroom after all the mushrooms that were present when I rode it.
The trail is actually a logging road with an earthen base through the dense coniferous forest. If you're following the Lužické Hory - Lausitzer Gebirge - Lusatian Mountains
or the Ceska Kamenice through Luzicke Hory
routes it will seem like a mellow route compared to all the climbing you've previously done.
