We'll start in the dirt parking lot across from the Morrison/C470 Conoco, ride into Bear Creek Lake Park, climb up the trail to the golf course(stop and regroup), then ride to the Platte River Trail. We'll turn South, and stop at Hudson Gardens for a bathroom break and to refill water bottles. This is about mile 18. We then continue South, pass under C470, head West, and stay on the C470 trail back to the Morrison Conoco.
To keep this at an intermediate pace, I'll maintain instantaneous speeds in the 15-16's on the flat sections of trail. At 17.0, I'll coast, or at least reduce pressure in my pedals.
This will be a no drop ride, so we'll regroup at the top of hills. While this pace is not especially quick, I would not say this is a beginner ride.
If any advanced or faster riders want to ride the same or a similar route at a much faster pace, please say so in the comments section. It would be great to have a choice of two rides at the same location!
