1. Greyval (FR): A promising horse with two wins over 1½m in France and a victory in a 9-runner listed event at Doncaster. Greyval boasts the highest average speed rating of 76.43 and a maximum rating of 83, further solidifying her position as the favourite. Estimated odds: 8/13.
2. Cape Cornwall Rose (IRE): A poor maiden on the Flat and making her hurdling debut in a tongue strap, she doesn’t seem to be a strong contender with lower speed ratings. Estimated odds: 50/1.
3. Crazy Maisie (IRE): A fair handicapper on the Flat, she has shown consistency in her performances but is competing against her own sex over hurdles for the first time. Her speed ratings are not impressive compared to the top contenders. Estimated odds: 20/1.
4. Golden Glance: Sold for 35,000 gns in November, she showed promise in her debut over hurdles and is expected to improve. With an average speed rating of 67.83 and a maximum rating of 74.55, Golden Glance’s speed ratings are competitive, indicating that she could be a strong contender. Estimated odds: 7/1.
5. Inkwell: Disappointed in her Wetherby bumper debut, she has since had a breathing operation, so there could be some improvement. However, her speed ratings are low compared to the top contenders. Estimated odds: 10/1.
6. Jolie Baie (FR): Offered little in her C&D bumper debut and is not considered a strong contender, as her speed ratings are significantly lower. Estimated odds: 66/1.
7. Moirai (IRE): Failed to impress on her debut at Market Rasen and is not expected to perform well in this race, with low speed ratings. Estimated odds: 25/1.
8. Qoya: Showed promise in her first hurdle race without a tongue strap, but her subsequent performance was disappointing. Qoya’s average speed rating is 62.05, and her maximum rating is 72.49. While her ratings are not as high as the top contenders, she still has the potential to put up a fight in the race. Estimated odds: 13/2.
9. Quality: Well beaten in previous races and not expected to be competitive, her speed ratings are relatively low compared to the top contenders. Estimated odds: 12/1.
10. Ravi Road (IRE): A modest maiden on the Flat who has shown little over hurdles. With an average speed rating of 54.67 and a maximum rating of 63.23, she is an unlikely contender for the win. Estimated odds: 33/1.
11. Rendition (IRE): A fair performer on the Flat but has not shown much in her three starts over hurdles. Rendition has an average speed rating of 57.61 and a maximum rating of 69.37. Although her ratings are not impressive compared to the top contenders, she could still show some improvement with the addition of cheekpieces. Estimated odds: 25/1.

In conclusion, Greyval (FR) seems to be the strongest contender in this race, based on form, odds, and speed ratings. Golden Glance and Qoya also have competitive speed ratings and should be strong challengers in the race. The other horses appear to have a lower chance of winning, requiring significant improvement to be competitive.
