There are seven meetings across Britain and Ireland, with six in the afternoon including two over jumps while Southwell is the sole evening card.
The feature meeting takes place at Newmarket, which includes two Group 1 races as well as the Cambridgeshire, one of the most historic handicaps in the calendar.
Racing Post betting editor, Keith Melrose, has provided his best bets on the Newmarket card, tackling some of the feature races on ITV.
14:27 Newmarket - Sun Goddess @ 6/4
15:00 Newmarket - Marco Polo @ 6/1
15:40 Newmarket bet365 Cambridgeshire - Erzindjan each-way @ 7/1
14:27 Newmarket - Sun Goddess @ 6/4
The Cheveley Park Stakes is being touted as the race of the season, with dual Group 1 winner Sun Goddess taking on another Group 1 winner in Senorita Bonita and Royal Ascot winner Libertango.
There are shades here of the 2010 Dewhurst, when Frankel, Dream Ahead and Saamidd all met in what was billed as a reckoning but just turned into another steamrollering from the untouchable Frankel.
Not that it is being suggested that Sun Goddess is on the same level, she is more like Dream Ahead in a lot of ways, but that may well be enough to win this race handily.
Sun Goddess has been campaigned with real intent as a two-year-old from the Aidan O'Brien yard. She has won four times since Libertango beat her at Royal Ascot in June, with each time arguably more impressive than the last.
She thumped Folsom Blues, who is a Group 1 winner himself now, at the Curragh in August and then won a valuable race at York in the sort of style that these big-field sprints are not meant to be won. Then she stepped up to seven furlongs and won the Moyglare Stud Stakes by more than six lengths.
The trip is secondary. What sets Sun Goddess apart is the way her stride lengthens and she puts distance into her rivals.
It is, as mentioned, reminiscent of Dream Ahead who won the colts' equivalent of this race, the Middle Park, by 10 lengths. The other two fillies are very good, but Sun Goddess looks a little bit special.
15:00 Newmarket - Marco Polo @ 6/1
Great Barrier Reef was a surprise absentee from the final declarations for the Middle Park Stakes. His trainer Aidan O'Brien remains doubly-represented, and Marco Polo looks an able substitute whose odds should be shorter.
This horse only made his debut in early-August, when he finished second to the reopposing Push The Boat Out, who is significantly shorter in the betting. Watching the race, you cannot get away from the feeling that had Marco Polo not been more obviously in need of the experience that he would have won.
That inexperience was not enough to stop him from going off prohibitively short for the Gimcrack Stakes at York 12 days later. He hated it, pulling hard and ruined his chance.
O'Brien has since given Marco Polo a bit of extra tutoring. His five-and-a-half-length win told us little about his potential, but it did suggest the lessons are getting through to him. His earlier runs hint at how high he can go, and he now looks to have the smarts to show his all.
15:40 Newmarket bet365 Cambridgeshire - Erzindjan each-way @ 7/1
The field for the bet365 Cambridgeshire almost always splits into two groups across the Rowley Mile. Find one in the right group and it becomes hard to miss out each-way, with bet365 offering six places to each-way bettors in the race.
Selection Erzindjan was able to reward each-way backers in the race last year, despite being in the "wrong" group. On the stands' side, the leaders let the opposition group build up too much of a lead. The first three home, and five of the first six, all came from the far-side group.
Not only did Erzindjan, drawn in 23, infiltrate that group, he did so by conceding a head start to his own cluster of runners. He was still last overall three furlongs out, before sweeping through to win his side by over four lengths.
The intervening 12 months have been pretty much all about returning to this race.
Erzindjan won over this rarely-used course and distance in May but has been marking time since and comes back off a mark just 2lb higher than last year. He is in stall 25 now, and if the leaders on his side keep up their end of the bargain he can expect to go close again.
