Riding westward across Colorado on the Golden Gravel Trail in Aug

I’m celebrating Colorado’s 150th birthday with a border-to-border bike ride over 3 weeks on the Golden Gravel Trail. Fairly casual pace, averaging 53 miles a day over 20 days, with rest days in Pueblo, Salida, and Crested Butte. I have to stick to an itinerary for planning purposes, so this is the outline:
Week 1 (Aug 1 – Aug 7) will cross the Eastern Plains, from the border to Pueblo
Week 2 (Aug 8 – 15) will cross the heights of the Rocky Mountains, from Pueblo to Crested Butte
Week 3 (Aug 15 – 21) will cross the Western Slope’s mesas and valleys, from Crested Butte to Moab, UT
I’m naming this the “Golden 150” Cross-Colorado Ride and hope to grow the group to up to 10-12 riders if possible!
