It felt great to get outside on the bikes today. The sun was shining, but the air temperature was cold. We’d get hot pumping up the hills on the hogback below Horsetooth Reservoir, then get blasted numb by the cold air on the downhills. The reservoir was frozen over, which made the ride feel exotic somehow. All told it made a great 19-mile loop from our doorstep, with an easy extention available to the southern access point at county road 38E.
