Dual Queen Mother Champion Chase hero Altior has been retired, trainer Nicky Henderson has announced.

In a glittering career that yielded 21 victories from 26 starts, Altior won 10 Grade One races.

He also won at the Cheltenham Festival four years in a row, with the Supreme Novices' Hurdle in 2016 and the Arkle Trophy in 2017 preceding his back-to-back triumphs in the Champion Chase in 2018 and 2019.

The jumping great went on an unbeaten 19-race run from October 2015 to April 2019, and amassed over €1.5m in prize money throughout his career.

Altior is going to spend his retirement with Mick Fitzgerald.

A former stable jockey of Henderson’s, Fitzgerald said: "It's an absolute honour to have a horse who has done as much as he has, and I’ve followed his career all the way through and am delighted that he is now going to be part of our family.

"We are going to get him to our place, let him settle in and just see how we get on. There are no plans whatsoever – we’re just going to let him tell us what he likes doing and take it from there, but one thing I can guarantee is he’s going to have a very nice time."
