Courtney Duncan: “I’m very happy for myself and the whole team. Dixon Racing and I have put a lot of work. We also have a small team back home, but it’s crucial. I just rode smooth and contained my lead and I am really happy. It was a good weekend, pretty close to perfect. I had two good starts in this technical track and it helped a lot.”
