I have just uploaded my first perl module to CPAN! :)

It is called GPS::Garmin::Connect and provides users with a very simple API to download their own activities from connect.garmin.com. This is the same code i am using for my list of runs.

Unfortunately Garmin has not yet released a public API to do this (and it doesn't look like it will in the near future) - so this module authorizes using the default login form and than uses a simple JSON call to fetch the data (just like Garmin's flash interface). It wouldn't be hard for Garmin to break the interface, but hopefully they won't mind that people actually use their own data...
