Rest of yesterday's races: War Of Attrition got the Gold Cup glory, but it was the West Cork-trained Whyso Mayo who broke new ground for the Irish by giving the visitors win number 10 of the festival in the Christies Foxhunters.

As was the case with so many of the Irish winners this week, Whyso Mayo's 20 to 1 victory didn't make many punters rich. However, for anyone who believed last year's tally of nine was an aberration, he was flesh and blood evidence of a new vintage era for Irish jump racing.

Just to emphasise the point, a 1-2-3 clean sweep in all three of the top championship races, the Champion Hurdle, the Gold Cup and the Champion Chase, was prevented only by the 50 to 1 outsider Mister McGoldrick, who spoiled the streak with a third on Wednesday's Champion Chase.

It was not a complete shock then to see the visitors dominate the Foxhunters to such an extent that Whyso Mayo was the first of five Irish-trained horses past the post.

Jockey Damian Murphy drove the winner to a length defeat of First Down Jets, and it provided Clonakilty trainer Raymond Hurley with the ultimate vindication of his decision to resume training.

Hurley trained the 1996 Gold Cup winner Imperial Call in the latter stages of his career, but handed in his licence for a brief period because of a chronic back problem.

"I had to give up because my back was so bad, but I started training again on my own with some point-to-pointers and this is my third season back," he said.

"From the first time I sat on him I knew there was something special about this horse. Damian was brilliant. He has his own way of riding the horse and getting him to jump. I knew Cheltenham would suit him, but that was nerve-racking."

It was also a first festival victory for Murphy: "I was cantering at Leopardstown last time when he unseated me at the third last. I kept him wide and let him see his fences today. He missed a few early on but was still super!"

The 11 to 4 favourite Harbour Pilot made several mistakes and was eventually pulled up, but favourite backers had a much better time than earlier in the week and Detroit City kicked it all off with a gutsy defeat of his Philip Hobbs stable companion Fair Along in the JCB Triumph Hurdle.

Richard Johnson was driving the well backed grey from the top of the hill, but Detroit City kept finding more and eventually went five lengths clear on the run-in.

Some firms gave the winner 16 to 1 quotes for next year's Champion Hurdle, but Hobbs said: "I can't see him being quick enough. The World Hurdle or novice chasing is more likely."

Tony McCoy notched his third winner of the week when the hottest favourite of the festival, the even-money Black Jack Ketchum, won the Brit Insurances Novice Hurdle in the style of a horse with a huge future.

Jonjo O'Neill was at home with flu, but the unbeaten Black Jack Ketchum proved his own rude good health with a nine-length defeat of Powerstation.

"The first day I won on him I said, 'This is a machine'. He's got a great attitude and never gets bothered," enthused McCoy.

Bookmakers, though, were bothered enough to make the winner a 6 to 1 second favourite for next year's World Hurdle.

McCoy had the leading rider award for the week snatched from him in the last race by his great friend and rival Ruby Walsh, who gave Desert Quest a superb ride to land the Vincent O'Brien County Hurdle. In the event, it was the one more runner-up placing, gained by Hedgehunter in the Gold Cup, that swung it Walsh's way.

As well as Whyso Mayo, there was another 20 to 1 winner in the Johnny Henderson Grand Annual, but only the most begrudging punter would have denied Nicky Henderson a success in the race commemorating his father, who died two years ago.

He threw four at the contest, and it was Greenhope who did the business, holding off the Irish hope Tiger Cry.

"Fairytales don't often happen and obviously this is very special. The whole family's here. Sister, brothers, everybody," said an emotional Henderson. "Andrew (Tinkler) has given him a wonderful ride. Mick Fitzgerald had the pick, but chose Tysou (pulled up)."

"I'd swap anything for that," exclaimed Tinkler. "He jumped for fun and fought all the way to the line."

Tiger Cry's trainer, Arthur Moore, said: "A super run. He found just one too good. He'll go now for a handicap at the Irish National meeting."

Greenhope was a third winner of the week for Henderson and a remarkable 31st of the Lambourn trainer's career. It also earned him the leading trainer award. He edged out Paul Nicholls on placed horses.
