Past 5 winners with Racelab Performance Rating:
This table outlines the Racelab rating achieved by each of the past five winners when taking out the Spring Champion Stakes. It gives an indication of the level required to win the race in recent years for a few different levels of weight carried. The rating is dependent on the WFA scale and factors in weight carried, hence Montefilia – as a 3YO filly – produced a lower Racelab rating due to the adjustment for her carrying 54.5kg.
| Date | Horse | Age | Sex | Weight | Margin | Racelab Rating |
| 26/10/24 | El Castello 3C | 56.5kg | 0.4L | 104.7 |
| 28/10/23 | Tom Kitten 3C | 56.5kg | 3.7L | 107.1 |
| 22/10/22 | Sharp ‘N’ Smart 3G | 56.5kg | 0.1L | 104.6 |
| 09/10/21 | Profondo 3C | 56.5kg | 2.2L | 105.6 |
| 10/10/20 | Montefilia 3F | 54.5kg | 0.8L | 103.2 |

The ratings/market:
Based off a range of data, speed map and recent form, Racelab has come up with its own 100% market, which is compared to the current market in the table below. Value exists where the Racelab price is lower than the current price:
| Runner | Racelab Rated Price | Current Market as of Thursday 4pm |
| Attica | $4.7 | $3.9 |
| Shangri La Boy | $4.7 | $3.6 |
| San Giovanni | $17 | $21 |
| Officiate | $41 | $26 |
| Master Of The Air | $63 | $26 |
| Federalist | $9 | $15 |
| Champagne Hero | $11 | $16 |
| Tambeloa | $360 | $91 |
| Southern Prince | $26 | $34 |
| Crusader Voyage | $98 | $34 |
| Within The Law | $7.2 | $5 |
| Queen Of Clubs | $61 | $21 |
| The Pearls (NZ) | $26 | $18 |
| Sheeza Diva | $39 | $34 |
| Pinot Nero | $1001 | $151 |
The verdict and betting strategy:
They should roll along at a decent clip here with 2, 10, 7 & 13 all pushing for positive positions in the run. Crusader Voyage gets the blinkers on for the first time so he may press on with it and lead. Shangri La Boy was impressive last start when winning the Gloaming Stakes and gets Nash Rawiller – expect him to be right up there but seems short enough. Out of the Gloaming Stakes I’m keen to follow Champagne Hero after a luckless run in the straight. He could improve here with the right run. Attica was strong from the back when winning the Dulcify Stakes however Federalist finished on his heels after the line and he looks ideally suited at the distance – just needs some luck from the wide draw. Within The Law is on the quick back up from the King Charles III Stakes but she did bleed from one nostril. I’m unsure if she will like the distance as well.
Suggested Bet:
Federalist (WIN)
Champagne Hero (WIN)
