Racing will go ahead at Newbury today, despite the bad weather.
The track passed an early morning inspection after officials covered the entire length of the track with frost sheets a few days ago to protect it from temperatures which fell to minus 3 overnight.
80 extra ground staff were bought in to help.
The first race will go ahead as planned at 12:50
