Got rather light-headed during the uphill bits, probably because I hadn't eaten since lunch. Went through about 16oz of Gatorade on the hike, then several glasses of water and a burrito after I got home.
Not really sore at the moment, and my mood is doing fine. I'm not even particularly tired, an hour afterward. If my feet didn't hurt, I could do it again. It wasn't nearly as intense as Sunday, but I still feel like I got something useful out of it. I'm pretty pleased.
Next time I need to find someplace more strenuous to hike, or go up and down the hill twice. Either way, should push myself harder -- and eat beforehand.
But it's still cool that I have a nice hill, with lots of trees and trails running around it, less than a half-hour walk from my apartment. I actually stumbled across a nice residential neighborhood on the hill -- I'd totally own a house there. There was ample parking, and (as evidenced by my hike) it's a decent walk from BART. (My current apartment is almost too close, honestly.) Too bad none of them were for sale.
