Persistent rain at Riverside International Speedway on Thursday afternoon and a forecast for the same Thursday evening have forced the cancellation of the open practice session that was scheduled for today. Teams should refer to Saturday’s schedule on the Ron MacGillivray Chev Buick GMC 150 event page for practice session times.

Advance reserved and general admission tickets for Saturday remain available through Friday – please find the order form on our event page under the ‘Tickets’ tab. General admission tickets (no reserve) will be available the gate on race day.
