Here are a couple of scenic loops you can do from the Quality Inn or nearby. Ideal for testing out your bike and legs. You can do either of these as a loop, or out-and-back from a point on the loop.
Eldorado Springs - Cherryvale (18.5 miles - RideWithGPS route) - Favorite local cycling roads, rolling, with a shallow climb to the town of Eldorado Springs and the mouth of Eldorado Canyon (prominent in rock climbing circles).
Morgul-Bismark (14.5 miles - RideWithGPS route) - A bit hillier, with a climb up to Hwy. 128, and great views from that mesa west to Eldorado Canyon and the Boulder Flatirons. There can be a bit of traffic on Hwy. 93.
