The Supreme Novice's Hurdle is the beginning point for some fantastic horses including Bula, Arkle, and Altior.

This race is for the speedier novice chasers and has been won by some of the greatest Jump horses including Moscow Flyer, Altior, and Sprinter Sacre. These all went onto win the Betway Queen Mother Champion Chase the following year.
The Ultima Handicap Chase is the first of five handicap chases run at The Festival. It's a Grade 3 steeplechase run over a distance of 3m abt 1f.
