The importance of a training log, which includes a list of logging applications and web sites
SportTracks - The best training log, with extensible functionality via plugins. This is my top recommendation for serious runners.
Dailymile - This is my top pick for social logging. Casual runners can use this site as their only training log, or combine it with SportTracks fir more sophisticated analytics.
