Poniros (100/1), a hurdles debutant for Willie Mullins, landed the Grade 1 JCB Triumph Hurdle on the final day of the 2025 Cheltenham Festival.
Owned by Tony Bloom, the son of Golden Horn previously ran on the flat for Ralph Beckett in England.
One of 11 representatives from Closutton in the 18-runner race, Poniros was only in sixth position as they approached the last hurdle in the straight.
East India Dock (5/4 favourite) took the lead into the final flight and was challenged by the Joe Donnelly-owned Lulamba, trained by Nicky Henderson.
Just as the James Owen-handled favourite looked to be heading for success, Poniros came with a strong drive from Jonjo O’Neill Jr to burst through for a neck win at the line.
Lulamba claimed the runner-up spot by three-quarters of a length from East India Dock under Sam Twiston-Davies, with Lady Vega Allen (14/1) and Paul Townend fourth, another length and three-quarters back.
