Same, here. One of our local MTB trails is used for regional race events and, frankly, it is way out of my league. Even some of the local MTB guys shake their head when you mention it. My issue is that I just don't have the strength to handle all the rapid and constantly changing vertical stuff. Even on the few level sections, the rocks and tree roots eat my Trek hardtail 26" bike. Really brutal. Found that I do better with the fat bike, even though it has no front suspension. Still can't handle the ups and downs, but, for sure, I'll take the fat bike every time on a backcountry trail and, especially, going off trail for a little bushwhacking, which I have done.
