There are many crazies around the Front Range; some have started doing a ride called the Morrison Monster, which is really just a large Front Range tour of the open space parks (there are many different ways to connect the open space parks). The ride is mainly trail with some road and bike path to connect the parks.
I have done different variations of this ride over the years....today was a big day for me filled with deep greens from all the rain we have had, wildflowers, and perfect dirt.
Route was Chimney > Apex > Matthew Winters > Red Rocks > Mt. Falcon > Lair O' Bear > Bear Creek > Green Mountain > Home.
52 miles with 7,500 feet of climbing
