Iowa heat race fields to be determined by one practice INDYCAR has amended the procedure to determine qualification groups for the three heat races to be held June 22 at Iowa Speedway to set the starting grid for the Iowa Corn Indy 250 the next night.
Qualification groups will be determined by lap times recorded by entries on the .875-mile oval in the second (45-minute) practice session (3:30 p.m. ET). Qualifications are scheduled for 7:15 p.m. (ET).
Race 1 will consist of the even-numbered positions, starting with the 10th-quickest practice time, and determine the even-numbered positions in the starting field from 10th down.
Race 2 will consist of the odd-numbered positions, starting with the ninth-quickest practice time, and determine the odd-numbered positions in the starting field from ninth down.
Race 3 will consist of drivers ranked one through eight from the practice. Results of Race 3 will determine the first four rows, with the winner taking the pole position.
