Flex time

I did a pretty good 24K run yesterday. It was better than last week; I didn't bonk, at least. My legs still get heavy after about 20K, but I think that's partly because I haven't been doing enough speed work or hills during the week. I also need to buy new shoes.I'm also thinking of doing a yoga class designed for runners. I am probably the least flexible person I know--I can barely touch my toes--but I have so little patience for the weight-lifting kind of strength training that I figure I should give it a try. I guess I'll drop in to the class this Thursday (but only because Lost isn't on right now) and see how it goes.
