Have you got any tips to do it, im really having enormous problem doing it.

Got it like 2 times and completely random. Don't wanna waste 50% of my run doing this skip. BibleThump

You Jump when your back foot is right at the edge (or just really close)

hold jump and left and blink when the middle of your head is at the middle pipe of the 3 in the background

It is kinda hard to get used to the timing, but once you understand it, you will start getting it quite often.

"when the middle of your head is at the middle pipe of the 3 in the background" Haven't understood this, i tried how you said but still can't get it :/

You need to blink when your character is in the same position than in Dacciox's second screenshot.

What's really important tho, is to jump really late from the ledge like in the first screenshot.
