Just ran half a marathon and got my first blister

Today I went out for my second long run since after I've been ill. The weather wasn't as nice as last Sunday and a lot windier too but too my surprise I've realised that I actually like a bit of head wind. Probably pushed it a little bit running just over 2 hrs and 21 km (half a marathon - yaaaaay!!!) compared to last week when I ran 1hr 33 min and 16.3 km. I know it's the worse thing you can do but the excitement from yesterday really filled me up and my knees where fine for most of the way so I kept on going.
I took in what Sam Murphy said yesterday about not doing your long runs at a really slow pace but somewhat closer to the pace you expect to run the actual marathon. I didn't want to push it too much so ran at a really comfortable speed and only started getting a little bit tired during the last couple of kilometers. It was no way near the feeling I had after the half marathon I did in 2004, which must mean I'm a lot fitter today :) The thought of running the double distance in 10 weeks time is scary, but I'm running half a marathon at a easy, steady pace in two hours, without having to walk, so I'm sure I'll be able to do the double distance :)
