If you're not already here get in the car and come to Steamboat. The courses are super fun and real-deal-enduro. Saturday's racing doesn't start till 3:00 so plenty of time to get practice in. Sunday's racing starts in the morning. You can sign up for just one day. A big pedal transition/climb greats riders for Saturday's stage followed by a course that drops from the top of the mountain with a mix of tight singletrack, high speeds, berms, rough, and a little climbing. I haven't ridden Sunday's 2 courses yet but hear one of them is fresh cut DH gnar.
