Got another ride in today. Ended up taking the Prairie Path down through Wheaton, into Warrenville, through Blackwell Forest Preserve up to McKee Marsh (where I go walking in the winter), then looped back home. Almost 56 miles in two days.
Again, dismayed with the average speed, as it sure seemed like I was moving faster than that. Also, when I got back and was putting the bicycle away, the front brakes were dragging heavily on the wheel (rim brakes). Wasn't like that when I left the house, so who knows how much of my ride today was extra effort with the brakes working against me.
The Blackwell/McKee area in more detail. That was a nice area, different scenery, some elevation changes (minor), and a couple of turns kept things interesting.
