It's happening. The race of the season is officially on as Aidan O'Brien revealed Constitution River is bang on target for a spine-tingling showdown with Ombudsman in the Juddmonte International at York on Wednesday week.

Following the superstar colt's smooth success in the Coral-Eclipse at Sandown last month, O'Brien said there were a number of options with regard to Constitution River's next outing – but a decision has been made and he is heading to the Knavesmire for the £1.5 million showpiece of the four-day Ebor meeting.

That sets up the contest we have all been craving as defending champion Ombudsman, who is the highest-rated horse in the world alongside Ka Ying Rising, will be waiting for Constitution River in what promises to be a humdinger of a race.
