Alan King's Edwardstone heads the five‑horse field for the Betgoodwin Sussex Champion Handicap Chase at Plumpton. The veteran, a former Henry VIII Novices’ Chase, Arkle and 2022 Tingle Creek winner, last ran a fourth in the Grade 1 Ascot Chase. Carrying top weight, he eyes a twelfth career win on his Plumpton debut.

Paul Nicholls’ Matterhorn, fresh from a fifth‑place win at Uttoxeter, arrives as the chief challenger, having been pulled up at Ascot’s Christmas meeting. Last year the eight‑year‑old chased home Sans Bruit here, but improved form suggests a real threat. Also in the mix, Secret Des Dieux seeks a hat‑trick for trainer James Owen, albeit carrying a 9‑lb penalty.

Course winners Kotmask and Scorsese complete the quintet, while the Sussex National later sees Invincible Nao defending his title over 3 m 4½ f with a higher weight. Across the weekend, Hong Kong’s superstar sprinter Ka Ying Rising aims for a 19th straight win in the Sha Tin Sprint Cup, already boasting more than £13 million in earnings.

With the Champion Chase offering a lucrative purse, a win would cement Edwardstone’s status as a versatile older chaser and boost Alan King’s standing in the summer campaign. Meanwhile, Ka Ying Rising’s pursuit of another Group 2 adds pressure on rivals Helios Express, Raging Blizzard and Tomodachi Kokoroe, promising a thrilling sprint showdown.
