Today's (Wednesday 6th August) race meeting at Chepstow has been called after microscopic parasitic worms were found on the course. The discovery of nematodes, which feed on the roots of grass and can potentially make the racing surface unstable, in small areas of the racecourse was made on 16th July. Following a course inspection last Wednesday (30th July), officials are hopeful that the Ladies Evening fixture scheduled for Thursday 14th August will get the go-ahead. A further course inspection by the British Horseracing Authority is taking place today. Customers who have already booked for today's meeting – which has been transferred to Lingfield Park by the British Horseracing Authority – are entitled to a full refund or transfer to another date. Chepstow's executive director Phil Bell said: "We have been working around the clock to ensure we deal with this issue and resume racing as soon as possible. "The nematode activity was discovered in its early stages and our ground staff team have been carrying out extensive remedial work to create a safe racing surface. "We are extremely disappointed that our season has been disrupted this summer and apologise to all of our customers. "We are doing all we can to ensure we can resume racing on Ladies Evening, one of our most popular fixtures of the year."
