Same problem man. I've used running-log.com for a long time (since before the crash where everyone lost everything) and I love the user interface and a lot of the features it has. I don't like running2win.com because you can't add in different intervals and then have it add up your mileage for you. I like saying on running-log.com:
3.5 warmup
whatever my workout is whether it be a bunch of intervals, a tempo, or a combination of the two
then 5mile cooldown
and having it add it all up for me and give me a total number but show the breakdown. Running2win.com doesn't work well for this and other than running-log.com I havne't seen any that do so if you find one let me know.
What I don't like about running-log.com is mostly that it is going nowhere and I don't trust it not to crash and burn. Their are small glitches that I (with my limited programming knowledge) could probably fix in a couple hours if I was allowed to access the code; the owner does nothing with it and has no plans to move forward with it or improve the site. And it needs some improvements. Also the team page feature SUCKS now although it used to be kick ass on the old version of running-log.com before the crash.
I actually plan on building my own running log website in the future, for the simple reason that I want one that has all the feature I want/need and I can make changes to it to suit my own needs. However, there is probably just about no money in this for me, and with my limited programming background would take me many many hours. So it is a project that is on the back burner for now.
