I used this site for a few weeks last year when I was reviewing online training logs. Here is my log:
http://runningahead.com/logs/3bd304da39294ede840f576dd54b3c53Note that you will have to flip back to January - March 2007 to see the workouts.
In my opinion, this is the best online training log out there. Shoe counter, graphs, user-defined database fields, mapping tools, graphics, and interface are all excellent and very, very robust. If I didn't use the blog, I would use this site.
Given that the tools, graphics, and useability on Running Ahead are so much better, then why do I still use the blog? Easy, the people. Despite having over 600 users, the Blog still has heart.
