The dates for the Nevada Trophy have been set for December 9th - 11th starting in Lovelock, Nevada. Two 15 hour days make up the main event for 4x and Duelsport bikes. A 12 hour novice race is also available. The event is a navigational/adventure, on/off road race that has been held for the last 8 years. You can get more information at offroadexperience.com.
I have been wanting to attend for the last 2 years and will get a chance this year.
