The Veridis Desert Challenge Festival is the largest and oldest nature sports festival in Israel. This is an entire weekend of sports activities for enthusiasts of all ages and levels. As part of the festival’s challenges, a number of mountain biking heats and competitive night runs are held for adults, youth and children, as well as riding trips for families and a mountain bike marathon with four heats. In addition, there is also the Spy Ultimate Challenge – an endurance competition, which combines two segments of mountain biking and one night running segment. This competition takes place in the midst of the unique desert landscapes and conditions, and offers three levels of difficulty and distance, designed for especially tough athletes. The event is held in the heart of the desert, at the Zohar stream basin, near the Dead Sea.
