Nice job, Birthday Boy! You may not have ridden long distance for a few years, but you do ride short-intermediate almost every day, which has kept your legs strong. Hills all the time, too.
I think you overdid it with the breakfast bars. I usually don't do any extra fueling for rides under 50 miles (I try to eat more protein afterwards) and for a 50-60 mile ride, if I start the day with a good breakfast, one snack is all I need.

No bike commute for me today. Yesterday was great and I overdid it, so today's a rest day. I had the four miles of commuting, but it was almost 40° and gloriously sunny, which we haven't seen in awhile. So I went out for lunch for another 7.5 miles. The commuting and lunch run were easy miles on the folder; trying not to get sweaty for the morning commute & lunch run, went a bit harder uphill and into a 13 mph wind on the way home.

So? I still had legs after work and took the single speed out for 19 miles after work and learned a bit about it. I have it geared my preference now, (66") and for some reason, it never occurred to me that I would ever be spun out except on ridiculous downhills. All it took was turning around and having that 13 mph wind at my back. Because of that, I was surprised to note that I got 2 PRs. I would have been even faster on my road bike, because I was spun out at 25 mph. Picked up a local legend too. Today, my legs are cooked and I'll rest them properly. Wind is even higher today, 18 mph so no love lost.

To spice up the thread a bit, here's a pic of the bike from last night. I added a (black) bottle cage after I took this pic. I need to order a silver finish one soon.
