Impervious sees Murphy back on the big stage Impervious looked a mare capable of giving trainer Colm Murphy some big days ahead when staying on strongly to land the Grade 2 O 'Flynn Group Irish EBF Mares Novice Chase at Cork. Wexford man Murphy enjoyed some memorable days with National Hunt stars such as Brave Inca and Big Zeb before prematurely calling time on his training career. Since renewing his licence, Murphy has been back among the winners but in Impervious he looks to have another very nice type. Unbeaten in two starts over fences before today, the mare showed real determination to overcome long time leader Dinoblue before quickening impressively to win going away. She looks the type to progress further and could even be suited to a stiffer stamina test. Colm Murphy said: "we'd have been disappointed if she wasn't ding-dong there and has had a nice clean run with her this year. "Settling her is the biggest worry with her but she settled really well again today. She was a bit careful jumping early-on but warmed up to it and her pedigree is all jumping. I wouldn't be afraid to step her up in trip either and there is plenty improvement to come from stepping her up. "We'll see how she comes out of this and there are plenty of nice options for her." He added "I have a lot of nice horses for Paul McKeon (owner) who unfortunately couldn't make it today. Unfortunately she is for sale if the right offer comes in as this is my business plan with Paul but without a doubt to stay in the yard." Additional reporting by Thomas Weekes
