The 2019 Flat season draws to a close on Champions Day at Ascot. With the amazing prize money on offer, it really is no surprise to see the fields as competitive as they are.

Leg one of the Betway 4 To Win is the Fillies’ and Mares’ race over a trip just shy of a mile-and-a-half.

Aidan O’Brien has won this race in both of the last two years, but it’s his fierce rival John Gosden who has the stronger-looking hand, with current favourite Star Catcher .

She is also the mount of Frankie Dettori, and there is no better jockey to have on your horse on the biggest of stages.

Jockey Harry Bentley is riding with confidence and his mount Antonia De Vega  has a solid chance. She’s improving and is lightly-raced, which could help at the end of a long season.

The Queen Elizabeth II Stakes betting has seen many moves in the past week, with the price for favourite The Revenant  coming in a lot.

He has had a hard season. Despite winning easily, top-graded races take it out of a horse mentally and this could be one step too far.

I’m surprised that this season's 2000 Guineas winner Magna Grecia  isn’t shorter in the betting. If he lines up in the same form, he’ll be incredibly tough to beat.

Favourites have won this race in all of the last three years and it doesn’t look like that will change this year.

Magical heads the field of nine. Providing that she’s not 'over the top' for the season, she should be better than this field.

At a bigger price, the Sir Michael Stoute-trained Regal Reality could outrun his odds. He’s a slow improver, but isn’t too far off top class and there is no doubt his trainer will have him primed for this big prize.

The Balmoral Handicap closes 4 To Win for the Flat season.

It’s not an easy race for punters, despite the market liking the look of recent Cambridgeshire winner Lord North  for Gosden and Dettori.

It’s very rare for Aidan O’Brien to have a runner in this race, and his mount Amedeo Modigliani could be well-handicapped.

His trainer waxed lyrical about him at the start of the season, so this could be a good way to get back to winning ways.

So Beloved will relish conditions and can run into a place at huge odds.
