Very different from here as well... I'd like to give these trails a try. Same as CD, over here in the Alps we have nothing but roots, rocks, mud and trees. The minimum climb over a very short ride is 400 m / 1300 ft. A nice lunch ride can be 800 m / 2600 ft climb.
It is normal over here to have to push/carry the bike on some climb. Only an e-bike could climb those. And even though we have some fast rolling downhill, there is DH sections that are as slow as the climb.
I'd really like to try some pure rock/dust trails in North America.
