Race Preview

6:25 Newmarket (July)

Friday 31 July 2026 ·4 runners KTB Selection: Aleatrix · 64/100

A small but select field of four lines up for the 6:25 at Newmarket (July) in a Class 3 Zyn Pacesetter Fillies' Novice Stakes over 1m2f on good to firm ground. With only four runners and limited previous experience between them the KTB numbers point to an open-looking contest where the principals sit close together on Fit ratings, the top three all rated in the mid-40s to low-60s. The race carries GBB and GBBPlus status and should provide an informative guide to future events at the track.

How the race shapes up

The pace shape is unclear with low confidence because there is simply not enough run-style evidence across the four runners to form a reliable picture. La Mariposa is the only horse with any defined pattern, tending to be held up and produce her effort late, though even that assessment comes with limited data. The key question is whether the race will develop into a test of stamina up the straight or whether a steady gallop allows the more experienced fillies to dominate without serious early pressure.

The contenders

Aleatrix KTB Fit 64/100

Form 1 · Ralph Beckett · Rhys Clutterbuck

Aleatrix arrives with a KTB Fit rating of 64 and is the clear selection. She showed plenty when landing her only start to date over today's 1m2f trip on good to firm ground, suggesting she possesses the required ability and scope. Ralph Beckett's yard posts a 16% strike rate at Newmarket (July) from 380 runs with an A/E of 0.92, while Rhys Clutterbuck has an excellent 19% strike rate from his small sample of 16 rides at the track with an A/E of 1.93. The pair combine with a 10/34 (29%) record together and an A/E of 1.31 plus £17.16 LSP. With only one run on the board the form must be treated with caution, yet the manner of that success and the yard's solid local record make her the one to beat from draw 2.

Without Prejudice KTB Fit 47/100

John & Thady Gosden · Robert Havlin

Without Prejudice is rated 47 on KTB Fit and represents the powerful John & Thady Gosden stable on debut. The yard holds a 19% strike rate at Newmarket (July) from 202 runs with an A/E of 0.86, while Robert Havlin posts a 13% strike rate from 433 rides at the track with an A/E of 0.91; together they have a 221/1048 (21%) record with an A/E of 0.87. As a first-time runner the assessment rests entirely on pedigree and sales background, with the By Starman sire line showing a 12% overall win rate from 816 runners. No course win on record and no previous racecourse form means she is something of an unknown, yet the stable's Newmarket record commands respect from draw 1.

La Mariposa KTB Fit 47/100

Form 582 · P Charalambous & J Clutterbuck · Pat Cosgrave

La Mariposa is another on a KTB Fit of 47 and steps up in class having shown modest but consistent form in three runs. She finished second of six here over a mile last time, confirming she handles the track, and she has been placed once from one run on good to firm. The yard has a 0% strike rate at Newmarket (July) from nine runs with an A/E of 0, while Pat Cosgrave holds an 11% strike rate from 322 rides here with an A/E of 0.91; the trainer-jockey combination is currently 0/6. Usually held up and producing her effort late, she now tackles 1m2f for the first time which poses a fresh question, though her placed effort over course and distance last time keeps her in the picture from draw 4.

The rest of the field

Golden IslandKTB Fit 44/100

Golden Island is a debutant rated 44 on KTB Fit with no racecourse experience, so the assessment rests entirely on pedigree and sales background. The yard has a 0% strike rate from 24 runs at this track with an A/E of 0 while Marco Ghiani operates at a solid 15% strike rate from 151 rides here; together they are 2/17 (12%) with an A/E of 1.18 plus £140.00 LSP. By Sottsass, whose progeny show a 12% overall win rate from 543 runners, she remains very much an unknown quantity on her first start from draw 3.

KTB verdict

Aleatrix stands out as the KTB Selection on the back of her decisive success over today's trip and ground on debut. The Beckett yard's respectable Newmarket (July) record and Clutterbuck's excellent strike rate at the venue add further layers of confidence, even if the bare form must be treated with a degree of caution given the small sample. Without Prejudice is the most interesting danger as a well-bred Gosden newcomer, while La Mariposa brings the most experience and has already shown she can handle the track. Golden Island is the biggest unknown but cannot be entirely dismissed in such a small field.
