Adventure Cycling has an update to their route because of the recent cycling ban in Black Hawk Co. If I am reading it correctly the options are to avoid the area completely (including the Rocky Mt National Park) or walk your bike through town which some of the distance has no shoulder or sidewalks. Yep like that’s going to make things better having cyclists walk in the roadway rather the ride.
And in the words of Adventure Cycling: "We continue to encourage you to support Bicycle Colorado in their bid to overturn the ban via legal and legislative means. If this ban is allowed to stand, a precedent will be set with statewide ramifications that we’d rather not think about." https://bicyclecolo.org/articles/black-hawk-bike-ban-pg1118.htm
