1st & 2nd Borders = Go in diagonal line so you can cover 2 borders at a time. Try to take as much damage on the way to the 2 borders but don't die while on the way. When you reach the 2 borders, kill yourself by building up, etc.

3rd & 4th Borders = Like for the 1st and 2nd borders, go in a diagonal line until you reach the 3rd & 4th borders.

Extra Tips: Jumping makes you slower (Except if you're on ice) so always try to jump less.
