WordPress Plugin for Garmin FIT Files

ShowFitFile is a WordPress Plugin to display FIT, GPX and TCX files as part of a blog. These files are usually generated by fitness watches and bike computers, such as those from Garmin, Polar and Suunto. The files contain all the information about a training session, such as route, speed, distance and data from sensors such as power meters and heart rate monitors.

This plugin displays the route information on a map, along with the event’s start time, distance, altitude gained & lost, and duration.
