I set out to do a 66 mile ride today. Left late. Didn't get out until 09:00. I enjoyed seeing new area I haven't seen before. This was the Santa Cruz multi-use path north of the Rillito path. This went all the way north of Twin Peaks Road. I then road down Silverbell to St Mary's to hook up with the Aviation Bikeway. What looked like the way to do so on the map turned out to not work and I had to look around to find how to get on it.
At about 3.5 hrs in to the ride I realized I had forgotten to eat my nutrition bar and was past due. I ate it then, but started feeling like I was bonking. I ended up eating another bar much quicker than I would have. I was behind and don't think I ever caught up. I was slower the rest of the way home.
I ended up cutting the ride short and only got in 58 miles. My knees were starting to get sore.
All in all, though, I enjoyed the ride. I love being out in nature. It is especially nice on the bike paths that are along the rivers where you don't have to worry about cars.
