Mother Nature wins again, I-35 Speedway is cancelled tonight March 24, 2018 due to wet and cold conditions. We will get the 2018 season started on Saturday March 31 with our regular classes of race cars and the ULMA Late Model series. The third time will be a charm! Just a reminder I-35 Speedway management may move a scheduled Saturday event to a better weather Sunday, however, Mother Nature has not provided a better weather Sunday this weekend.
