If you are a serious jogger | hiker | bicyclist, there's a good chance that you want to improve and to be better than the last outing. But how? You analyze your track data, of course. You need a GPS device that can log in GPX format first, your Android can do that. These 4 applications will help you analyze your track data, that was logged by GPS.

1. Google Earth
   the most simple of all, it only plots your track data on satellite photo, with no analyzing whatsoever, not even distance and duration.
   Here's how to install Google Earth on Ubuntu.
   
2. Andrew Gee's GPX Viewer
   GPX Viewer is an application that allows users to easily view GPS traces they have created in the GPX file format. It plots the track on openstreetmap and shows distance, average speed, maximum speed, duration.
   You must add the PPA before installing it.
   
3. Viking (already available at Ubuntu repository)
   GPS Data and Topo Analyzer, Explorer, and Manager. Not so much in analyzing but it can shows speed profiles over distance.
   
   
   
4. Qball Cow and Andrew Harvey's GPX Viewer (only available in source)
   is simply the best.
   
   This application features :
   
   • Show multiple GPX files.
   • Show waypoints and multiple tracks per gpx file.
   • Highlight selected track.
   • Show distance, duration, average, moving average, max speed, moving time and gps points.
   • Zooming
   • Smoothing of speed graph.
   • Highlighting points in speed graph on map.
   • Show time vs.  height graph, speed,  acceleration (hori/verti), distance, etc.
   • Playback of a track.
   • Show track on different types of maps (depends on support in libchamplain)

Unfortunately there's no .deb file nor PPA for easy installing on Ubuntu. You must compile it first, I wrote how to compile GPX Viewer on Ubuntu here.

There you go, 4 application to help you be a better jogger | hiker | bicyclist, have fun outdoor!
