Thursday's meeting at Wincanton has been abandoned due to a waterlogged track.
Clerk of the course Barry Johnson initially called an inspection for raceday morning after substantial overnight rain.
However, he brought that check forward to 12.30pm following further rain this morning, before eventually calling the meeting off around 12 noon.
Johnson said on Wednesday: "We've had 34mm of rain since one o'clock this morning and it's still raining now.
"I have never seen it so wet. It is supposed to stop later today and for there to be a dry afternoon, but there is more rain forecast for tomorrow and we have no chance of recovering in time for racing."
