Course Generator is a software which can estimate your time in road running races, trails, ultra trails or treks.

I created Course Generator in 2008 for my first 100 km ultra trail. Since then, I added a lot of features and it has been used by a lot of french ultra-runner. Up to the version 3.88 it has been written in C# and now java is used in order to be cross platform (Windows, Mac OS and Linux) and multilingual.

Course Generator is free (donation are welcome ;) ), multi platform (Windows, Mac and Linux), multi-language (currently English and French) and open source under GPL V3.

In order to works, Course Generator (also called CG) need a GPS file (GPX file) and some extra informations.

With Course Generator you can :

• Estimate your time at each point of the track.
• Set field type (the difficulty to the track: road, trail...) at each point of the track
• Set your fatigue coefficient and how it will evolve during the race
• Set the refueling time (to eat, to drink, to sleep...)
• Set the cut-off time on points of the track. CG will give you give an alert if you are late
• Set the recovery coefficient after a rest
• Set a name and a comment for each position of the track
• Take into account the effect of the night during
• Take into account the effect of the altitude (over 1500m)
• See your track on an OpenStreetMap map
• Generate a mini road book where you will see the track profile and all the most important information of your race (position name, time, hour, altitude, elevation gain...)
• Get statistics of your race
• Analyze a race
• Invert the track direction
• Define a new start point for a "looping track"
• Insert a track at the beginning or the end of another track
• Extract a part of the track
• Save all your specific settings in a CGX file (a Course Generator specific format)
• Have offline maps (OpenStreetMap)
• Use Metric or Imperial measure
• Display the speed as speed or pace

• You need a version 8 (minimum) of the java runtime environment (JRE)
• Download the latest version ('exe' file) from the Release section
• Execute the installer
• Execute "course_generator"
• The first time you execute the program it will ask you if you want to install the standard curves. Answer "yes"
• That's all. Enjoy ;)

• You need a version 8 (minimum) of the java runtime environment (JRE)
• Download the latest version ('zip' file) from the Release section
• Unzip all the files in a folder
• Execute "course_generator"
• The first time you execute the program it will ask you if you want to install the standard curves. Answer "yes"

• You need a version 8 (minimum) of the java runtime environment (JRE)
• Download the latest version from the Release section
• Uncompress the archive in a directory (where you want)
• Give the execution right to "course_generator.sh"
• Execute "course_generator.sh"

• That's all. Enjoy ;)

Note : Curves, log and tiles are store in "~/.course_generator".

I have no MacOS system but the installation is probably the same as LINUX.

Note : User curves, log and tiles are stored in "~/.course_generator".
