This achievement is quite a doozy, the tiny ice ramps don't give much height, and you can easily fall if you go off course.
As the Pastafarian, you can just keep running. The gaps aren't that large, and the light bridge can help you get over them with ease. Just keep your hand off the jump button, and know when to turn right or left, and you will soon earn the 50 Power cells as a reward. If you are playing with the post-update Pastafarian, you should try to use ramps and fast horizontal movement to reinforce the bridge.
For the Skater, you can just try to use his speed to get over the gaps, though, if he is too slow, he can still fall into it. Therefore, keep track of his speed.
