Be prepared for a time of your life experience.
The folks who run this are just as stoked as you are to climb up and zip down. They are an awesome bunch who help everyone share the experience to its max.
If it is cold at all at hte bottom prepare yourself and bundle up. It will be super windy and chilly up top. The hike isn't bad at all just about 15 minutes.
If you want to go fast, squeeze yourself tight, toes front and body straight. You will fly!
