Irish Dominate Bumper Betting When Coral yesterday opened betting on all twenty races at the Cheltenham Festival, not surprisingly Irish-trained horses figured very prominently for the Weatherbys Champion Bumper.Of the nine contenders quoted at 20/1 or under, all but one hails from this side of the Irish Sea. The Edward O´Grady yard is particularly well represented with According To Billy at 12/1, Overbury Affair 14/1 and Sidalcea 20/1.John Kiely, who has enjoyed a high level of success in the bumper sphere of late, has both Ceeawayhome at 10/1 and Blazing Liss at 14s quoted. Impressive dual-scorer, Martinstown tops the list as 5/1 favourite, whilst Willie Mullins has one of the 10/1 co second market-leaders, Templelusk.
