TERRE HAUTE, Ind. — Saturated grounds and continuous, ongoing thunderstorms on race day morning has forced postponement of Sunday’s 20th running of the Sumar Classic featuring the USAC Silver Crown National Championship at the Terre Haute Action Track.
USAC and Terre Haute Action Track officials are working on a reschedule date for the Sumar Classic.
The USAC Silver Crown season will now open on May 19-20 at the Belleville High Banks in Kansas as the series returns to the venue for the first time since 2015.
