I don't know how all the runners on this forum log their training runs, but I have been using Garmin Trianing centre to keep tabs on my runs. Today I found a site, Sport Tracks, that allows you to download all info stored on any of the Garmin Forerunner series, and tabulates and maps it, giving calories used, height loss and gain and pretty much everything else. It's much better than Garmin's own training centre software. If anyone wants to give it a try, it's free, it can be found here

Just remember to save the log each time you exit and that way, imported runs and routes will be saved. If you don't you'll have to import the runs from your Garmin to your PC at each visit.
