Hello all!
We are in the planning phase for next summer's Raging River MTB Festival. We are unofficially scheduled for June 21-23 2019.

Before we nail down specifics we'd love to hear from you. Please take a moment to answer these questions. Your feedback is greatly appreciated!

In this survey, there's a "team" format proposed for the XC race. This would be 2 people racing together for one overall time. The only way to accomplish this is to change the XC loop to include mostly Fire Road/Gravel to get up to the towers, then descending the Ridge Trail back to the park to complete one lap. Distance is approximately 16mls. This loop would not use any of the outer Black or Double Black Diamond trails. Team's would do two laps(one per rider) to complete the course.

Feel free to leave any additional feedback or comments on what is your ideal race format.

Appreciate your help!
