I am lloking for some decent training software for a macbook with Excel 2008. Cyclestats does not work on my system.
I use this http://www.theprolog.com/ on my mac. I think the version I have is the "premium version," but I got it when it was free.
If you are getting a powertap or something, there is an application called Golden Cheetah, which will help you track that. http://goldencheetah.org/
