Constitution Hill returns for Cheltenham Festival's opening day

The Cheltenham Festival 2025 begins today, featuring a renamed opening race in memory of jockey Michael O’Sullivan. The event will host seven races, including the Champion Hurdle, where unbeaten horse Constitution Hill aims to reclaim his title. Constitution Hill returns after a year off due to health issues, having last raced successfully in January. He faces competition from Brighterdaysahead, who recently won a major Irish race, and last year's Champion Hurdle winner, State Man. Other notable races include the Arkle Novices’ Chase and the Mares’ Hurdle, with Lossiemouth now favored in the latter after switching from the Champion Hurdle. The day promises exciting matchups and strong betting interest.
