This is an easy way to get through Colorado. When you get to the part with patches of deeper snow,around the third or fourth patch, there should be a place with a lot of trees. Weave through those trees, and there should be a railroad track. Grind on that track and after a while, look at your position and you should be in first place.(Unless there is somebody is in front of you,which is most likely)I'm not promising that you will win every time, but it helps to break the time record.

On the right side of the course, between the ramp with two rocks in front of it and the ramp with the green pole in front of it, there is a group of trees, you can grind on the fallen tree to reach the secret tunnel.

All you have to do is get to the bottom of the avalanche stage. You can also go on a little shortcut on the right around in the begining. It is harder so I wouldn't go in there.

To get 18,000 points easily go to Big Air in Japan. Before you reach the three bridges there will be a ramp which might look little. Jump of this ramp and gets lots of air and then hold in the up button.You then should be able to do a triple foward flip.
