I like Runningahead too. I haven't used the "community" type tools yet, but it's a pretty decent balance of features + non-crazymaking interface. (For a good example of a crazymaking interface, see beginnertriathlete, perhaps the kludgiest training log ever, in spite of its many features -- I just can't get past the kludginess). I haven't tried to use Buckeye yet, but it seems a little kludgy to me after registering and looking through it. Daily Mile is actually extremely slick and clever and non-kludgy in what it does, and it has great sharing/social networking capabilities, but I don't think it offers enough data/ways to control data, unfortunately.
