I am in the red Quadbike and William is on the silver one. We had to do a series of challenges and the first one was to race around the track and we had to do three laps and we had to stay inbetween the cones or there was penalty.The next one was to keep behind the insructor. She got off her Quadbike at certain obsticles to show us how to complete it. The final challenge was to enter a bombshell safely and get out of it. I would say that that was the most difficult.
