Hey all, I pretty consistently bike up Lookout Mountain once every week or two but otherwise am lagree/pilates only thanks to a knee injury and tiring of the repetition quickly. I need some variation in my life but road cycling gives me a lot of anxiety. Is there anywhere I can go to bike that's: within an hour of central Denver, with a lot of incline, and where cars aren't allowed (and isn't totally covered in snow)? Thanks!
