Three and a half hour workout today, and afterward I felt peppy. Peppy! Of course, I had to immediately sit down at my desk and have not moved for the past four hours, so things may have taken a turn for the worse. I'll have to get up in a minute and see if I can walk.
On a completely unrelated note, I'm having the worst time finding "reading" material for these long workouts. Despite declaring that I just wanted to listen to brain candy, I really haven't been able to find any that I can stand. I've started several semi-popular novels, but they sucked so much I just couldn't go on. I did listen to the entirety of "Twilight," even though it was mind-meltingly bad, just to see what all the fuss was about. (I still don't understand what all the fuss was about.)
I had better luck going on a mini 19th century British literature kick, despite having hated "Wuthering Heights." I just finished "Jane Eyre" and absolutely loved it, and today I heard "The Strange Case of Dr. Jekyll and Mr. Hyde," which was also pretty good. (Oh, and before that I listened to an audio version of "Chi Running," which was excellent, but it probably would have been more useful to listen to it on a run rather than a bike ride.)
I'm thinking that I'll stop trying to find good modern stuff and just stick with the classics and nonfiction. At least then, even if I don't like the book, it still will have been good for me.
