[2][3] Constitution Hill is a bay gelding with a small white star bred by the Worcestershire-based Sally Noott.
He has sired numerous good National Hunt winners including L'Autonomie (Grande Course de Haies d'Auteuil), Blue Lord (Paddy's Reward Club Chase), Royale Pagaille (Betfair Chase) and Mick Jazz (Ryanair Hurdle).
The gelding was sent to the Goffs Horses in Training sale a month later and was bought for £120,000 by Nicky Henderson on behalf of Michael Buckley.
On his first appearance under National Hunt rules, Constitution Hill started the 85/40 second choice in the betting for a nine-runner novice hurdle over two miles on good to soft ground at Sandown Park Racecourse on 4 December 2021.
After settling behind the leaders he took the lead after jumping the final hurdle and drew away to win by nine lengths in "impressive" fashion.
"[10] On the opening day of the 2022 Cheltenham Festival Constitution Hill started the 9/4 joint favourite alongside the Willie Mullins-trained Dysart Dynamo for the Supreme Novices' Hurdle.
He overtook his stable companion two hurdles from the finish and pulled right away from his rivals to win by twenty-two lengths despite being eased down by De Boinville in the closing stages.
He just does it for you.”[14] A month after his win at Newcastle Constitution Hill went off the 1/7 favourite for the Christmas Hurdle at Kempton Park Racecourse with Epatante being the only one of his four opponents to start at odds of less than 20/1.
"[16] In the Champion Hurdle on 14 March 2023, Constitution Hill started the 4/11 favourite ahead of the Irish gelding State Man, the winner of four consecutive Grade 1 races.
He tracked the front-running Rubaud before taking the lead at the second last flight and won "easily" by nine and a half lengths.
[21] After the race Henderson said “I’ve not seen one jump better, that’s the great secret to all these good two-milers, and we have been very lucky over the years going way back when with See You Then, and then Binocular, Epatante and Buveur d'Air – it is the way they get from A to B.
"[22] After a poor performance in a training gallop and an unsatisfactory blood test it was announced that Constitution Hill would not defend his Champion Hurdle title.
