Dinoblue is now just 6/4 to win the Mares’ Chase according to the latest Cheltenham Festival 2025 odds from Ladbrokes.
Already the favourite, Willie Mullins’ chestnut mare saw her odds cut to 6/4 in the afternoon of March 6.
Another JP McManus-owned mare, Bioluminescence, has been the other notable market mover in the Mares' Chase, drifting from 4/1 to 5/1

That means means the five mares behind the favourite are all priced between 5/1 and 6/1.
Cal Gildart of Ladbrokes said: “Dinoblue might be pulling away from the pack, but with rivals priced so closely, this one might not be as cut-and-dried as it looks.
Above are the odds for the nine favourites heading into the Mares' Chase at Cheltenham this year, all of whom are priced below 33/1.
