To get a run accepted do I have to show the entire run or can I just show the end with the in-game timer like my 1-3 Any% run?

You've to show the full run

Ok thank you.

Or show a clip of the end of the level with the timer and the medals. I've done this many times especially on very tight WRs on levels such as W6-4 because it's more comfortable then leaning over a camera. Full video of the run would be preferred. Make sure you film the medals at the end. This is crucial evidence that you didn't cheat/edit the level

Ok thank you, I think the end of the world stat will work better for me thx.
