Monday afternoon's Flat meeting at Hamilton Park has been abandoned due to a waterlogged track after more substantial rain.
Originally an inspection was called for 11.30am on Sunday but that was brought forward to 10am in light of a poor forecast.
However, further rain overnight left officials with no choice and in the end the decision was inevitable.
Clerk of the course Hazel Peplinski said: "It was a relatively easy decision, it's completely waterlogged.
"It's been a sad end to the season which never really got going.
"We've had around 22 inches of rain this summer when you'd normally expect eight or nine."
