This event is our new, fall invitational. Please note that the run groups are different, and noted on the schedule below. All open wheel cars will have two races Saturday. All closed wheel cars will have two races Saturday as well, one being a 60 min relay race. Qualifying from Saturday morning will determine your grid position for the first race. Grid position for the following races will be determined by your finish in the previous one, rolling through to the Sunday races. There will be no qualifying on Sunday - we'll get right to the racing! If you miss qualifying or a race you will start at the back the following session.
Our IRDC Year End Banquet will be held from 6:30pm - 8:30pm in the event space above the classroom. Everyone is invited to attend! Registered drivers & volunteers get free tickets, but please make sure to check it off when you register so we know our numbers.
