How do I earn Diamond Trophies in the time-based daily/weekly challenges?

I'm trying to get to the 11th Level of Awesomeness in Rayman Legends. No matter how hard I try, I can't seem to get higher than gold in the normal challenges and silver in the extreme challenges, which means its going to take me four to six months of daily effort. For the distance challenges, I just need to keep practicing. I need help with the timed challenges.

From looking at videos, it seems there are ways of boosting that will increase my speed and ways of landing that keep my momentum. But I can't seem to find any useful tutorials explanations for how to do this. What moves do I need to learn in order to start challenging for Diamond Cups?

For example, at about the 9 second mark in this videom, you can see the player's speed/momentum pick up, but I can't tell what he or she is doing to get up to that speed.

You can see the same speed-up around the 21 second mark of this video, but the player isn't able to maintain it for long.

The speedup happens almost immediately in this video:

You need to press your attack button to gain little speed boosts. When you get better at this technique, you can press the button as soon as the previous animation ends and keep your speed consistently up. Also, if you attack and then immediately jump, you go even faster, but this technique is significantly more difficult because you must make sure that you are not jumping at the wrong places. One other note, do not use the attack speed boost up inclines because this will actually reduce your speed. It takes some practice, but once you get the technique down, your times will drastically improve.
