I attended the GGR DE #1 this past weekend 3/5-6/2022 up at Thunderhill. I had run the West configuration 2 years ago, but never had done the East.
I used a combination of Assetto Corso, Ross Bently course walks and some onboard video from Andy Lee to prep and memorize the turns.
On Saturday I ran 2:25, 2:24, 2:19, 2:17 best session times. On Sunday, I ran 2:16, 2:15.9, 2:15.1.
