I've only just started trying out athleticore.com, but it seems like a very simple, minimalist web site. You can input your training and it will give you some very basic reports. The ability to output the data to Excel may give some extra flexibility. The site seems to be focused on running groups, either educational or other organizations. Ratings (out of 5)
- Ease of use: 3 - Quite easy to use, though not as smooth as Dailymile.com. All data must be manually input, with no support for specific devices.
- Reporting and analysis: 1 - only the most basic of reports, though it does output to Excel.
- Flexibility: 1 - Very few reports and little data is tracked.
- Social: 1 - There appears to be some social networking built in, but only within users of the site.
- Data Capture: None - all data must be manually entered
- Summary: Very simple, not very powerful; it seems like the web equivalent of Pen and Paper.
- 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.
