You'll have to use these splits that have been configured to the Elite Force speedrun mod. The vanilla game's splits won't really work.

Elite Force speedrun mod splits

Here are the dlls for the Elite Reinforce patch made by Sphere.

This mod includes some console commands useful for speedrunning.

Elite Reinforce 

Simply unzip the file in your Star Trek Elite Force folder and replace existing files.

This mod includes Quake World/Source strafes, Jedi Knight bobbing on lands, and autohop. It is built on Sphere's Elite Reinforce mod.

Commands:

- g_autohop (set to 1 to allow holding space for jumping)
- g_movementType (set to 1 for Source movement)
- g_landBobbing (set to 1 to make jumping feel more like JK2/JKA)

Source movement, JK2 landing bobs, and autohop mod

This download includes an edited config to prevent crashing.

INSTALL:

Simply unzip the folder in your Star Trek Elite Force folder. To launch the mod, double click the included .bat. Alternatively, you can load the mod through the "mods" tab in the ingame menu and type "map sr_borg1" in the console.

Speedrun maps (easy install)

Simply place the pk3 file into BaseEF, then type "map sr_borg1" in the console to load the first map.
