Andrew Balding and Aidan O'Brien are going toe-to-toe in the race to be crowned champion trainer.
O'Brien nosed ahead in the standings after Minnie Hauk made her return to the winner's enclosure in the British Champions Fillies & Mares Stakes on Champions Day, but Mount Atlas' shock success in the Long Distance Cup ensured that Balding remains within touching distance of the Ballydoyle maestro.
The gap between the top two is now less than £100,000 heading into the final key fixtures of the season.
Despite both recording winners on British Champions Day, both trainers were could have come away with a little more from the meeting.
O'Brien's Queenstown finished runner-up to Mount Atlas in the Long Distance Cup and Constitution River beat just one rival home in the Champion Stakes.
Kalpana went off a well-backed favourite to seal a hat-trick of wins in the Fillies & Mares Stakes, however, ran a disappointing seventh; likely feeling the effects of a busy campaign.
Although the championship runs up until the end of the year, there are only a few more meetings that boast big prize money pots.
There is almost £500,000 up for grabs on the second day of Doncaster's Futurity Trophy weekend, where O'Brien will have a strong hand in the feature contest where £155,953 goes to the winner.
O'Brien's Noble Exhibit is the current favourite for the race, while Balding has just two outsiders with entries.
Despite having a gap to make up, Balding is sure to have more UK-based runners until the championship's conclusion, meaning that his rival will likely have to take out at least one more big prize before the year is out.
