The Group 3, $88,000 Arc Trial, the Arc prep that rarely produces a runner in the Prix de l&rsquo;Arc de Triomphe, will have its 14th running at Newbury on Friday.\r\nOnly one of the race&rsquo;s winners has ever run in the Arc in the same year he has won the Trial, that being Fantastic Light, who finished 11th behind Montjeu in 1999. The best Arc finish by an Arc Trial participant came in its inaugural running of 1997 when third-place Swain was seventh in the Arc behind Peintre Celebre.\r\nOnly two of the nine runners in Friday&rsquo;s 1 3/8-mile renewal are nominated to the Arc, but one of them, Campanologist, may have designs on the big race. A 5-year-old son of Kingmambo, he is Godolphin&rsquo;s leading Arc candidate at this point, and is coming off Group 1 victories in Germany at 1 1/2 miles in the Deutschland-Preis and the Rheinland-Pokal. As a result, he will be spotting his rivals seven to 14 pounds with Ted Durcan aboard.\r\nThe other Arc nominee is Monitor Closely. Trained by Michael Bell, he won the Group 2 Great Voltigeur Stakes last summer and was third in the St. Leger but has looked dull in a pair of Group 2 outings of late.\r\nRainbow Peak will be the post-time favorite. Trained by Michael Jarvis, this 4-year-old son of Hernando has never been worse than second in six career starts, stepping up to Group 3 company for the first time on Aug. 20 at York when he was a neck runner-up to Godolphin&rsquo;s revitalized Rio de la Plata in the 1 1/8-mile Strensall Stakes. A three-time winner at 1 1/4 miles against lesser, Rainbow Peak will be ridden by Neil Callan.
