While three of the top four in ante-post betting on the Prix de l'Arc de Triomphe go on trial in France and Ireland this weekend, international riding star Mick Kinane reckons he already has an ace up his sleeve for the big race on October 4. Kinane has been booked to ride Epsom Derby winner High-Rise, currently 6-1 third favourite for the Arc. The Luca Cumani-trained colt, also runner-up to Swain in the King George VI and Queen Elizabeth Diamond Stakes at Ascot in July, will go straight to Longchamp without another run. It was announced this week that French champion jockey Olivier Peslier had lost the ride on High-Rise. Connections moved quickly to secure Kinane when Peslier's commitment to trainer Andre Fabre appeared likely to upset their riding plans. Anthony Stroud, the representative of Darley Stud Management, under whose managerial umbrella High-Rise races, said the move to book Kinane for the Arc was the logical one. 'Olivier has so many options for Andre Fabre that it was very apparent he could not continue his association with High-Rise in the Arc. Mick does not have any commitments to either Dermot Weld or Aidan O'Brien in that race, so he was the obvious choice,' Stroud pointed out. Kinane rode the last British-trained winner of the Arc, Carroll House, sent out by Michael Jarvis in 1989; Lammtarra in 1995, saddled by Saeed bin Suroor, was technically Dubai-trained. Peslier, whose chief commitment in France is to the Wildenstein family, has a variety of possible Arc mounts, including Fragrant Mix, currently at 12-1, and Limpid, a 14-1 chance. Both are trained by Fabre. Ladbrokes have installed Dream Well, the Prix du Jockey-Club and Irish Derby winner, 7-2 favourite for the Arc, while Swain, who runs in the Irish Champion Stakes today, is second favourite at 5-1. High-Rise is next at 6-1, while Sea Wave, the easy winner of the Great Voltigeur Stakes at York, is an 8-1 chance. Swain is a 5-2 favourite to take the Irish Champion Stakes, his final prep race before an incredible fourth consecutive crack at the Arc. Sheik Mohammed and Godolphin are particularly keen for the six-year-old to win a Group One contest over a mile and a quarter to enhance his credentials as a stallion. Frankie Dettori by-passes today's St Leger at Doncaster to ride Swain at Leopardstown. Stablemates Dream Well and Croco Rouge, first and second in the Prix du Jockey-Club at Chantilly at the end of May, are due to meet again in tomorrow's Prix Niel, over 2,400 metres, one of three so-called Arc Trials at Longchamp. To hold favouritism for the Arc, Dream Well will have to turn in an authoritative display, which trainer Pascal Bary fully expects. Sea Wave, who misses the St Leger in favour of the Prix Niel, also adds interest to the field. In the Prix Foy - for the older horses - the well-performed Fragrant Mix, a possible Arc mount for Peslier, is expected to start favourite, although hardened campaigner Posidonas is in the field. A field of 11 runners is expected for the Prix Vermeille, also over 2,400 metres, for the fillies. Double Trigger appropriately went out of British racing in a blaze of glory on Town Moor on Thursday, making all to land his third Great North Eastern Railway Doncaster Cup and the unqualified admiration of trainer Mark Johnston and an army of devoted fans. The bold-striding seven-year-old will now have only one more start - in the Prix du Cadran at Longchamp on October 3 - before retiring to stud, where Johnston predicts he will have a successful career as a National Hunt stallion. 'Double Trigger has become more and more special to us in the yard this season, especially as the idea that he will be missing next year is starting to sink in,' Johnston said. 'It has been such a comeback by this horse this season, particularly as many were prepared to write him off,' he added. With characteristic fight and determination, the white-faced chestnut repelled the game Canon Can, as well as a few others on turning for home, over half a mile out. Only when the Barry Hills-trained Busy Flight loomed large on the inside did he look in any danger. However, it was almost as if Double Trigger knew this was his swan song on British soil. He put his head down and fought grimly under Darryll Holland to hold on to his lead, while Busy Flight, having his first outing since May due to an injury, just ran out of fitness and dropped away. On the line, Double Trigger, sent off 9-4 joint-favourite, beat Busy Flight, an 11-2 chance, by one length to become the first horse since Beeswing in 1841 to win the Doncaster Cup three times.
