In the interest of our racers and fans, tonight’s program (7-31-21) at I-35 Speedway has been cancelled. Mother Nature sent rainstorm after rainstorm after rainstorm to the track and with this much moisture and lack of drying time, racing tonight would not meet the standards we have established at I-35 Speedway of a super smooth and fast track. We would be fighting mud all night from the time haulers would enter the track and try to park until the last race of the night and our fans are trying to leave the parking lot. We will miss everyone tonight, we look forward to seeing you next Saturday August 7, 2021, for the McCarthy Auto Group Kids Night Weekly Racing.
