Lossiemouth was labelled a "star mare" after cementing herself in Cheltenham Festival folklore with a dominant victory in the Champion Hurdle.
With 2023 champion Constitution Hill not running having switched from jumps to Flat racing, the field was wide open.
But it was Lossiemouth, the 2024 and 2025 winner of the Mares' Hurdle, who justified her standing as 7-5 favourite.
With Paul Townend on board, the mare finished in front of Gordon Elliott's Brighterdaysahead and Dan Skelton's The New Lion.
Trainer Willie Mullins told ITV: "She's a star mare. To come back four years in a row, let alone win, that is incredible.
"When I put her cheek pieces on her I thought, wow, that's the old Lossiemouth."
