This afternoon's meeting at Wincanton goes ahead after passing a fourth inspection.
Officials at the track were on frost alert this morning after overnight temperatures dropped to minus 4C.
Although the track was "80 per cent raceable" following an initial precautionary inspection at 8am, further checks at 9.30am and 11am proved inconclusive, leading to a fourth look at midday.
Clerk of the course Barry Johnson said after the latter: "We're all good to go. The stewards have been on the track and they're happy.
"A couple of jockeys went out about half an hour ago as well and we're happy to give it a go."
