Fontwell’s meeting on Thursday must pass a precautionary inspection at 8am due to the threat of frost.

Temperatures dipped to a low of minus 3.5C on Tuesday evening and are only due to rise to a high of 2C on Wednesday.

It could get even colder on Wednesday evening but there is hope that a daytime high of 4C may help thaw the track in time.

Wincanton on Friday is also under threat due to frost.

Having performed a minor miracle to get the course raceable on Saturday, clerk of the course Dan Cooper and his team now face a different problem.

The course is currently frozen in places and temperatures overnight could reach minus 3C before racing but a daytime high of 5C offers hope.

The meetings at Doncaster and Leicester on Wednesday both passed inspections before racing.

There were no issues at all at Doncaster but Leicester did need three inspections before getting the go-ahead, the latter at 12 noon.
