Thursday night's meeting at Oxford Stadium has been abandoned following heavy overnight snow.
Officials called the meeting off to save the public travelling and in an attempt to get Friday's BAGS meeting on.
Racing manager Gary Baiden said: "We have a lot of snow on the track itself which we are in the process of clearing.
"We have cancelled tonight in a bid to have a chance for tomorrow's BAGS meeting.
"Our chances are good at the minute because the surface is good, but our big worry is monitoring the snow overnight."
