I want to see the link too!
I'm glad you asked this question, it made me think it through for myself. Essentially, you have to look at the route for each day and the map of the area and figure it out, there is on one way to do it.
The ideas below could need to change depending on the timing of the race, road closures, or maybe someone will come up with something better. Last year close to the race date, there were suggested viewing locations and information when the race would come through various spots, and road closures, on the race site. That stuff is not there yet.
In any case, if you are planning to be out on the race route for a long time on your bike, plan on bringing warm clothes and a rain jacket, it can thunderstorm in the mountains and you will want to be prepared. If you have a non-riding driver for the RV, the logistics can be different, too, you can part the RV on top of a pass and ride up to it. Last year I drove SAG for my friends (in a car, not RV) because I was injured, and that worked well for them.
1) circuit in aspen - stay in aspen, ride maroon bells before or after race, depending on race time, extend west out to Basalt or Carbondale if you want more miles, there is a great bike path (will be crowded)
2) aspen to breck over independence pass - ride indy early, watch race at top, ride back to aspen, drive to breck
3) breck to steamboat - watch race leave breck, drive to copper or Minturn, ride copper triangle, drive to avon/vail. This might or might not work depending on the race timing and rode closures, the Copper Triangle takes 5-8 hours to ride.
4) steamboat to beaver creek - rest day or ride up vail pass & back to Avon in time for finish, or ride out on race route, or ride up to the ski area (short), or ride towards Leadville over Battle Mountain, or ride the Copper Triangle early if you didn't do it the day before.
5) Vail Pass tt - drive to Copper, ride up the other side of the pass to watch finishes, or ride up vail pass from the vail side, depending on if you have any legs left, and if you want to be stuck up there all day until the race is over. best would be if you have someone move the RV to Copper/Frisco/Dillon area, and most of the group ride up from vail to the top, then continue on to Copper. Drive down to the front range afterwards, stay in boulder or loveland or estes Park or wherever
6) Loveland - Ft C - many choices.
stay in Estes, ride TRR or Hwy 7, back to town before race goes thru.
Stay in the flats, watchi in the flats, ride in the flats - I would watnt to watch start then ride over to Horsetooth and watch them climb a steep part
Stay in the flats(loveland) ride up the race route before the race, watch the race once at Glen Haven then ride back down and watch it again at drake
7) Denver circuit race - can do anything before/after the race, but it's going to be busy. I would probably do something short before and then get over to the race to get a good spot, it will be very busy. or if you are sick of spectating at this point, drive to boulder and ride one of the iconic canyon climbs, lefthand to ward, flagstaff, etc.
