A bit on the long side, but easily "doable"..
Start early, enjoy a meal in Walden,
Look for the sheep on Mt. Evans,
Enjoy Bear Creek canyon..
Putt...
Thats a great ride Putt, thats almost the exact route, we took earlier this year when the snow melted. Mt Evans is closed for the year IIRC but the rest should be clear. Poudre Canyon is one of my favorites, you gotta watch the gravel but its a nice ride.
Are you up in my State again rubing salt into my wounds? You just wait a year and I am going to show you.
