I decided to compile a list of some of Time Attack videos for you newbies to check out. These were all done by a player named JarrodMitchell, who used to set world record times and upload them to YouTube a few years back. Some of these runs have since been bested (only slightly), but Jarrod's videos were always the most impressive to me. Some of the tricks you see in these videos were pioneered by him, but others were adapted from the videos of other speedrunners.
Before you dive into Time Attack, yourselves, check out some of these videos for extremely helpful shortcuts. I'd love to see the speedrunning community spring back to life for SotC, since I think it has one of the best Time Attack modes in gaming.

If anyone finds good videos for the ones I am missing, please post them for me to add to the list. I am at work right now, so my video searching resources are limited.
Also, one more ProTip for the day: If you go up next to the corpse of a defeated colossus during a normal playthrough and press O, it will let you replay the fight in "Reminiscence Mode." This just let's you fight that same colossus again only with a film grain effect. Enjoy!
Edit: Here are three videos compiling all of the fastest recorded Time Attack runs, if you'd rather watch it that way:
