I've been reading Tim Noakes's Waterlogged, which is about endurance exercise and hydration and electrolyte balance, and really ought to be titled, "The Makers of Gatorade Are Lying to You!" It has me contemplating weighing myself before and after exercise to see if I can measure my sweat rate, and wondering if there is any convenient way I can measure the sodium concentration of my sweat. This whole fitness thing really is an excuse to do experimental biochemistry by other means, isn't it?
I've been trying to "listen to my body" as I ramp up my training for the Warrior Dash at the end of October, trying to find that happy line between pushing my body hard enough that I get strength and endurance adaptations and pushing my body hard enough that I get an overuse injury. "Listening to your body" is easier when it doesn't change what it's saying every 20 minutes. When I woke up this morning, it was pretty unequivocally saying, "We are so not going running this morning." By the time I actually got out of bed, it was saying, "Well, maybe a short easy run would be fine." So, I went running and actually had a really good run, although I kept it short, because one thing I have learned that my body is really good at saying is, "Wow, in retrospect, that was overdoing it." So far, I seem to be fine.
Stopped to chat with a guy who was walking his dog in the park where I run. He's trying to get together a little local running group. Haven't decided if I'll join in - running with others can be fun, but I like being out there with just me and my iPod, too.
