Q4Run is a modification for Quake4. Primarily it's based on trickjumping and combining tricks. The first idea behind this mod was to implement timers which makes it possible to finish a specific "run" map in a certain time and then improve it afterwards. Every run will be documented in a demo named after name of player and map and time. If you want you can share those demos with other players so they can watch your skill or can help you to improve it. Comparing to others' times you can try to beat them or be proud of yourself because of better records.
This tutorial explains how you set up your q4radiant correctly, so you can create your own q4run maps from the beginning on without any troubles.

Before you can play around with the entities of q4run you have to make some settings first.
I always create a completely new folder for editing purposes only, so I don't get any problems on servers later because of a different version of the map or because of different pk4 files. Extract q4run again into your quake4 folder and name it something like q4runeditor. Now you also have to edit your shortcut to the editor:
Run the application and look if you have a target_timerstart in your entitieslist. It should appear because the editor also loaded the q4run definition files besides the normal quake4 files. For the last step go to edit -> preferences and link the map path to the q4runeditor folder.
